ABS resin is listed as one of substances approved under FDA regulations. Moreover, despite restrictions on compounding ingredients, the elution level of monomer components and usage, it can also be deployed in equipment usable repeatedly.

To obtain the Blue Angel mark, printer housings must be made of non-halogen flame-retardant materials. The use of antimony trioxide is also limited. We offer non-halogen type grades to sensure compliance with these requirements.

NSF stands for “National Sanitation Foundation” and denotes a voluntary third-party certification organization in the United States, which sets outt, tests and certifies sanitary standards for plumbing areas.

Our manufacturing process uses zero , specified CFCs, which deplete ozone, as raw materials.

The FMVSS acronym stands for “Federal Motor Vehicle Safety Standard.” The compliance of our automotive grades has been confirmed. FMVSS302 is one of the US test standards implemented for vehicle materials and a standard for testing combustion performance (burn rate).

The UL file number of the former UMG ABS Co., Ltd. product is E47016 and the UL file number of the former Techno Polymer Co., Ltd. product is E54297.

Please refer to the following link for the flammability class specified by UL94 :

UL94 flammability test methods include UL94 HB, UL94 V-0, UL94 V-1, UL94 V-2, UL94 5VA and UL94 5VB, which cover most of the flammability of ABS resin. Please see below for an image of the test method.

Two types of certification formats exist for documents certifying UL certification.

Since this exceeds the certification scope, it will no longer be treated as a certified product. A thinner wall - certified grade may be used or product testing may be required.

The RTI (Relative Thermal Index) is a temperature index of heat - aging resistance by UL and RTI is the temperature at which more than half the original electrical and mechanical properties can be retained during extended exposure. The RTI varies depending on the type and grade of resin. Under UL’s individual product standards, the required RTI level differs depending on the product type and the part in which it is used. Standard ABS resin has an RTI of 60ºC.

Conditions vary depending on the product type. The drying conditions are listed in the molding condition table, which can be downloaded from the injection molding conditions on the “Products” page of this site.

For general ABS resin, a depth is of 2/100 to 3/100, the land length of 3 to 5 mm and width of 5 to 20 mm. The standard gas vent groove depth is 0.5 to 1.0 mm.

This is more likely when the temperature of the mold, or resin is low, or the injection speed is high. It is also determined by the mold design. Please refer to troubleshooting for details.

Silver streaks can appear on the surface of injection-molded products for various reasons.

ABS resin is the easiest resin on which to paint among general-purpose and engineering plastics. Paintability largely depends on the material composition, the surface condition of the molded product and the selection of the paint itself.

There are three types cases of color codes. Please refer to the following link.

Typically, customers are requested to provide a color sample and the chosen grade is blended with a coloring agent (dye/pigment) for tinting. During this phase, the coloring material is selected while taking into account various regulations, requisite product characteristics and the molding method. Originally, the hue of the colored product should align with the color sample across all light sources (lighting conditions). However, due to the aforementioned selection of coloring materials, achieving this may pose challenges. Consequently, specifying the light source for the usage environment or color evaluation from the outset is recommended.

Our company sells colored products, but we do not produce or sell master batches for coloring.

The coloring of a single object will appear to differ in if illuminated by different light sources in a phenomenon known as color rendering. Metamerism is a phenomenon whereby two colors with different spectral distributions appear the same under specific lighting conditions. Colors with the same spectral characteristics look the same, regardless of lighting conditions. However, if the spectral characteristics of one side (for example, one of the color samples and the color plate) are differ, they will also look different under certain lighting conditions. Even if they look the same, they will look different under other lighting conditions.

Our special coloring range includes scope to , develop metallic colors and sell such materials. However, the specific properties of of metallic materials may make it, difficult to produce the requested color in certain cases. This is due to issues like variance in the metallic feeling and conspicuous weld lines.

The key is to clarify the requirements and quality for resin-molded products and select a compliant resin grade accordingly. Aspects to take into consideration include product thickness (for rigidity), corner R (resin fluidity consideration, corner stress concentration relaxation), shape, position and number of ribs and bosses, gate design, punching gradient, and degassing.

For general ABS resin, ν=0.35 to 0.38.

When simulating resin flow in a mold, data representing the flow characteristics of the resin grade used for molding is required. We provide the above data for your use. Please send a request to our sales department using the email form, specifying the grade you are considering and the all other information required.

Outcomes fluctuate based on the type of chemical utilized. Dissolved chemicals are not applicable. For ABS resin chemical immersion test results, please click “See details” below. Moreover, interacting with chemicals in a strained environment may induce cracking (environmental stress cracking). For thorough explanations and mitigations pertaining to environmental stress cracking, please refer to the “Troubleshooting” page. Various grades, enhanced for resistance to environmental stress cracking, are available for purchase.

Since ABS resin absorbs water, it must be allowed to dry when molding. The water absorption level of general-purpose grades is about 0.5 to 0.7% when left in the atmosphere at room temperature and 1% for some heat-resistant and special grades. Please download and refer to the information on injection molding conditions for each product on the Product Introduction page. For injection molding, dry with a water absorption rate of 0.05% or less.

The oxygen index for flame-retardant type ABS resin is approximately 22 to 35, depending on the flame-retardant performance and approximately 18 for flame-retardant type ABS resin.

Standard ABS resin has a volume resistivity of 10E+15 to 10E+18ohm･cm and a dielectric breakdown strength of 14-20kv/mm.

The ignition temperature of ABS resin is approximately 500℃, but this figure fluctuates depending on the combustion environment conditions.

Standard ABS resin has a dielectric constant of 2.4-5.0 (60Hz) and a dissipation factor of 0.004-0.008 (10E+6Hz).

ABS resin exhibits glass transition temperatures in two temperature regions, approximately 200℃ apart. A transition point at roughly -80 to -90ºC on the low temperature side is precipitated by butadiene rubber and another transition point of around 120ºC on the high temperature side is prompted by PSAN. The low temperature side characteristic significantly contributes to the ABS resin’s low temperature impact strength, while the high temperature side dictates its heat resistance. An example of measuring dynamic shear elastic properties can be referenced for further understanding. The glass transition temperature can be ascertained by identifying the peak temperature of tanδ.

Given the unique sample preparation and test conditions for each resin, comparing and evaluating different resins with a single test method is impossible. We recommend researching the differences in the products you plan to consider. Reference books on plastics that compare numerical values may be useful, e.g. “Plastic Reader : Performance Table of Main Thermoplastic Plastics”. Please also read the disclaimer before viewing.

It is 0.4 to 0.6% for ABS and 0.2 to 0.5% for AS as a general rule. Please refer to the following link.

ABS resin is a ternary copolymer that polymerizes three types of monomers: : acrylonitrile, styrene and butadiene. Please refer to the following link.

Both resins are within the spectrum between general -purpose resins and engineering plastics. Their surface hardness, coloration and design accuracy explain why they are used in many products. Favorable moldability also makes such resin suitable for wide-ranging parts. Please refer to the following link.

The designation “ABS resin” derives from the initials of the monomers composing the resin. Various rubbers are employed as substitutes for butadiene rubber to enhance weather resistance, including AES, ASA, SAS and ACS resins for example. Our company proactively utilizes diverse rubber types, excluding chlorinated rubber, to leverage their attributes. We refer to them collectively as AXS resins and label them as high-performance styrenic resins, inclusive of weather-resistant grades.

We introduce the test methods below, illustrating test items which are most often queried. Please click below for more details.

A red-hot wire called a glow wire is heated to a specified temperature on the flat part of the sample, then pressed against the test surface for a certain period of time. There are five types of red-hot wire test temperatures, starting at 550ºC in increments of 100ºC and peaking at 960ºC.

Products molded under appropriate management conditions can be recycled as materials without significant deterioration in their physical properties provided this is done after normal use over an extended period. Thermal recycling is also possible when material recycling becomes difficult due to an inability to separate it from other resins or materials.

Hazardous heavy metals of lead, cadmium, hexavalent chromium, mercury and their compounds are not used as raw materials for our products. Please refer to the following link.

Specific brominated flame - retardants include PBBs (polybrominated biphenyls) and PBDEs (polybrominated diphenyl ethers), which encompass several varieties depending on the number of bromines involved. Although our products previously included such items in, flame-retardant grades, we have already discontinued usage of these grades.

Antimony compounds are used as flame-retardant aids, except for some flame-retardant grades. You can check the grades used by ISO11469 display or MSDS.

Our manufacturing process uses zero , specified CFCs, which deplete ozone, as raw materials.

The majority of products are colored utilizing ABS resin, due to its excellent coloring properties. This means that any examination of environmentally hazardous substances must include investigation and analysis of the coloring agent. Numerous customer-specified colors for product coloring exist and even when a survey request is made for red or black, pinpointing the precise coloring agent may be challenging. To facilitate and expedite the process, understanding particulars like the grade name and color code is imperative. Please directly consult the sales personnel responsible for the customer and note that a fee is generally levied for submitting data that includes measurements.
