Chimei Polylac PA-777E Ultra High Heat ABS Resin

Polylac® PA-777E High Heat Moderate Impact ABS Resin

Polylac PA-777E ABS Resin is a heat-resistant material for tough jobs. It handles heat up to 129°C (Vicat) without warping and stays strong in cold (-30°C) with 12 KJ/m² impact. Easy to mold (4.5 melt flow) and stable (0.3–0.6% shrinkage), it reduces errors. UL94 HB rated for safety. Chimei’s PA-777E offers durability and ease for products that last.

Manufacturer: CHIMEI
Application: Shells for heat producing household appliances, hair dryer tubes, iron casings, heaters, auto parts, water tank covers
Character: Ultra-high heat resistance, moderate impact strength

Ultra-High Heat Resistance

Withstands temperatures up to 129°C (Vicat Softening) and 121°C (Heat Distortion), perfect for parts exposed to heat.

Balanced Strength & Impact Resistance

It offers 12 KJ/m² impact strength at room temperature and stays tough even at -30°C, ideal for durable, long-lasting products.

Easy to Mold, Stable Shrinkage

Melt flow index of 4.5 ml/10 min ensures smooth processing, while low mold shrinkage (0.3–0.6%) guarantees precise part dimensions.

Applications

Shells for ovens, heaters, and hair dryers
Automotive under-hood components (e.g., sensor housings)
Durable water tank covers and pump parts
Iron casings and small appliance housings
