Suzhou Yifuhui New Material Co., Ltd. is proud to offer the Chimei ABS PA-777E (POLYLAC PA-777E), an engineering-grade ABS resin specially formulated for the demanding automotive industry. With ultra-high heat resistance and moderate impact strength, this material is designed to withstand elevated temperatures in engine compartments, dashboards, and interior trims while maintaining structural integrity. Our global supply chain, with annual exports exceeding US$10 million, ensures reliable delivery to markets across North America, South America, Europe, and Asia.
As a trusted trading partner, we provide consistent quality and competitive pricing for this premium ABS grade. Whether you need components for under-hood applications or aesthetic interior parts, PA-777E delivers the performance and processability you expect from a top-tier engineering resin.
Product Features & Technical Advantages
Ultra-High Heat Resistance: Heat deflection temperature (HDT) typically exceeds 110°C under 1.82 MPa load, making it ideal for parts near heat sources.
Moderate Impact Strength: Balanced toughness reduces risk of brittle fracture during assembly and use, while maintaining rigidity.
Excellent Dimensional Stability: Low shrinkage and warpage ensure tight tolerances for complex auto parts.
Good Chemical Resistance: Resists oils, greases, and mild cleaning agents commonly encountered in automotive environments.
Easy Processing: Optimized for injection molding with wide processing window; can be molded in standard equipment.
Customizable Color: Available in natural (off-white) or black, with color matching optional upon request.
Consistent Quality: Each batch is tested for melt flow, impact, and thermal properties to ensure repeatable results.
Typical Applications in Automotive
| Application | Benefit |
|---|---|
| Dashboard components & instrument panels | Heat resistance prevents warping from sun exposure and HVAC vents. |
| Interior trim parts (door panels, center consoles) | Moderate impact withstands accidental bumps; good surface finish for aesthetic appeal. |
| Engine bay covers & air intake ducts | Ultra-high heat resistance near engine block; dimensional stability retains fit. |
| Electrical connectors & housings | Good electrical insulation and heat resistance; moderate impact prevents cracking. |

Frequently Asked Questions (FAQ)
Q: What is the main advantage of PA-777E over standard ABS?
A: PA-777E offers significantly higher heat resistance (HDT ≥ 110°C) compared to general-purpose ABS (typically 90–100°C), plus moderate impact strength for demanding automotive applications.Q: Can this material be used for exterior auto parts?
A: It is primarily designed for interior and under-hood components where heat resistance is critical. For exterior parts requiring UV stability, we recommend consulting our team for potential UV-stabilized options or coating solutions.Q: What processing conditions are recommended for injection molding?
A: Typical melt temperature range is 220–260°C, mold temperature 50–80°C. Drying at 80–90°C for 2–4 hours is essential to avoid splay marks. We can provide a detailed processing guide upon request.Q: Is this material recyclable?
A: Yes, ABS is recyclable. However, we recommend using virgin material for high-heat applications to maintain consistent performance. Recycled grades may have reduced heat resistance.Q: Do you offer color matching or custom colors?
A: Yes, we can provide color matching services for black, natural, or custom colors. Minimum order quantities may apply for custom colors. Please contact us for details.Q: What is the typical lead time for bulk orders?
A: For standard natural/black grades, lead time is approximately 7–15 days after order confirmation, depending on quantity. Custom colors may require 15–25 days. Express shipping is available for urgent samples.Q: Can you supply a Certificate of Analysis (COA) with each batch?
A: Absolutely. We provide COA including melt flow, impact, and HDT values for every batch to ensure traceability and quality consistency.Q: What payment terms do you accept?
A: We accept T/T transfer, L/C at sight, and other negotiable terms for established customers. For first-time orders, a 30% deposit is typically required.
Note: The above technical values are typical and may vary slightly with processing conditions. For specific application requirements, please consult our technical team. All information is provided in good faith but without warranty.
