Key Features & Benefits
High Dimensional Stability: The 920-555 grade exhibits minimal shrinkage and warpage, ensuring electronic enclosures maintain precise dimensions even after exposure to elevated temperatures during assembly or operation.
Excellent Heat Resistance: With an HDT of 83°C, this material can withstand the thermal challenges of wave soldering, reflow processes, and continuous use in warm environments without deformation.
Good Impact Strength: The balanced impact resistance protects enclosures from accidental drops or mechanical stress, reducing the risk of cracking during assembly or transportation.
Superior Flowability: The optimized melt flow rate allows for easy injection molding of complex geometries, thin walls, and intricate details – a critical requirement for modern electronic housings.
Consistent Quality: As a Toray product, the 920-555 is manufactured under strict quality control, ensuring batch-to-batch consistency for reliable production.
Customizable Color Options: Available in natural (transparent) form, and we can supply pre-colored granules based on your RAL or Pantone reference – request a sample for color matching.
Global Supply Chain: Shipped from major Chinese ports (Shanghai, Ningbo, Qingdao) with flexible packaging options to meet your inventory requirements.
Application Recommendations
Toray ABS 920-555 is particularly suitable for:
Electronic enclosures & housings (e.g., routers, switches, power adapters, sensors)
Internal structural components in appliances and automotive electronics
Connectors, sockets, and terminal blocks requiring dimensional stability
Parts exposed to moderate heat (up to 80°C continuous) and mechanical loads
Processing Guidelines
Recommended injection molding conditions for achieving optimal results:
| Parameter | Typical Range |

Frequently Asked Questions (FAQ)
Q1: What does HDT 83°C mean for my application?
A: HDT (Heat Deflection Temperature) of 83°C indicates that the material begins to deform under a load of 0.45 MPa at that temperature. For electronic enclosures that may be exposed to soldering heat or warm environments, this grade provides a safety margin below 80°C continuous use, ensuring dimensional stability.
Q2: Can this material be used for outdoor applications?
A: ABS is generally not UV-resistant without additives. For outdoor use, we recommend adding UV stabilizers or using a UV-resistant coating. Please consult our technical team for specific recommendations.
Q3: Is the material RoHS and REACH compliant?
A: Yes, Toray ABS 920-555 meets the requirements of RoHS (Restriction of Hazardous Substances) and REACH regulations. We can provide compliance certificates upon request.
Q4: What is the typical shrinkage rate?
A: The mold shrinkage for this grade is approximately 0.4-0.7%, depending on processing conditions. The high dimensional stability helps minimize post-molding warpage.
Q5: How should I store the granules?
A: Store in a dry, cool environment (below 40°C) and keep the original packaging sealed to prevent moisture absorption. For best results, dry the material before processing even if stored properly.
Q6: Can you supply small quantities for trial?
A: Yes, we offer sample quantities (e.g., 25kg bags) for evaluation. Larger orders are shipped in 25kg bags on pallets, or in bulk bags as per your preference.
Q7: What is the lead time for standard orders?
A: For standard natural grade, lead time is 5-7 working days after payment confirmation. Custom colors may require additional 10-15 days depending on the color matching process.
Q8: Does this grade contain any fillers or reinforcements?
A: No, Toray ABS 920-555 is an unfilled ABS homopolymer. It does not contain glass fibers or mineral fillers, offering a smooth surface finish and good impact resistance.
