Suzhou Yifuhui New Material Co., Ltd. is a professional trading company with over US$10 million annual export value, serving global markets including North America, South America, Europe, and Asia. We are proud to introduce our Ultra High Temperature Tolerant POLYLAC PA-777E ABS – a specialized engineering plastic designed specifically for demanding automotive applications. This grade offers exceptional heat resistance combined with robust mechanical properties, making it the ideal choice for water tank cover components that operate under high thermal stress. Our material helps automotive manufacturers achieve longer product life and improved safety performance.
The POLYLAC PA-777E is a modified ABS resin that withstands elevated temperatures without significant deformation or loss of strength. Unlike standard ABS, this grade is formulated to maintain dimensional stability and impact resistance even in continuous exposure to heat. Below are its key technical characteristics:
| Parameter | Typical Value | Unit |
|---|---|---|
| Density | 1.04 – 1.06 | g/cm³ |
| Melt Flow Rate (220°C/10kg) | 15 – 25 | g/10min |
| Tensile Strength (at yield) | 45 – 55 | MPa |
| Flexural Modulus | 2200 – 2500 | MPa |
| Izod Impact Strength (23°C, notched) | 180 – 220 | J/m |
| Heat Deflection Temperature (1.82 MPa) | 100 – 110 | °C |
| Vicat Softening Temperature (50N, 50°C/h) | 115 – 125 | °C |
Key Product Features:
Ultra-high thermal resistance: Maintains mechanical integrity even in continuous service near 100°C, preventing warpage or creep in water tank covers.
Excellent impact strength: Retains toughness at room temperature and moderately elevated temperatures, reducing risks of cracking under thermal cycling or vibration.
Good flowability: Optimized melt flow for injection molding complex geometries with thin walls, ensuring consistent fill and minimal sink marks.
Surface finish: Delivers smooth, glossy appearance suitable for visible automotive components without additional painting.
Chemical resistance: Resists common automotive fluids such as coolants, oils, and mild alkaline solutions, prolonging service life.
Easy processing: Compatible with standard injection molding machines; drying recommended at 80-90°C for 2-4 hours before molding.
Benefits for Automotive Water Tank Cover Applications:
Reduces the risk of cover deformation under engine bay heat, ensuring proper sealing and preventing coolant leaks.
Lightweight compared to metal alternatives, contributing to overall vehicle fuel efficiency.
Cost-effective alternative to high-performance engineering plastics like PA or PPS, while still meeting stringent thermal requirements.
Customizable color options available to match OEM specifications or simplify inventory management.

Frequently Asked Questions (FAQ)
Q1: What is the maximum continuous service temperature for PA-777E ABS?
A: The material can be used continuously at temperatures up to approximately 100°C (212°F) without significant loss of mechanical properties. For short-term peaks, it can withstand slightly higher temperatures.
Q2: Is this grade suitable for injection molding? Any special drying requirements?
A: Yes, it is designed for injection molding. Drying at 80–90°C for 2–4 hours is recommended to remove moisture and prevent surface defects like splay marks.
Q3: Can I get custom colors for this ABS?
A: Yes, we offer custom color matching services. Please provide a color code or sample for reference. Minimum order quantity may apply.
Q4: How does PA-777E compare to standard ABS grades?
A: PA-777E has significantly higher heat deflection temperature (about 20–30°C higher) and better thermal stability, making it suitable for under-hood automotive parts where standard ABS might soften or deform.
Q5: Is this material recyclable?
A: ABS is generally recyclable, but the specific recycling process depends on local facilities. We recommend consulting with recyclers for post-industrial waste.
Q6: What packaging options are available for export?
A: We offer standard packaging in 25kg bags or 500kg–1000kg super sacks, plus palletized and shrink-wrapped for container loading. Custom packaging can be arranged upon request.
Q7: Do you provide Material Safety Data Sheet (MSDS) and technical data sheets?
A: Yes, we provide comprehensive documentation including MSDS and TDS for all our products. Please contact our sales team to obtain them.
Q8: What is the typical lead time for bulk orders?
A: Lead time is usually 7–15 working days after confirmation, depending on order quantity and current stock. Rush orders can be accommodated with prior arrangement.
