Superior Impact Resistance

POLYLAC® PA-747S delivers exceptional toughness with Izod impact strength of 34 KJ/m² (23°C) and 23 KJ/m² (-30°C), ensuring parts withstand drops, vibrations, and sudden stress. Perfect for automotive interiors or protective equipment exposed to harsh conditions.

Reliable Heat Resistance

With a Vicat softening temperature of 103°C and heat distortion temperature (HDT) of 96°C (annealed), this extrusion ABS maintains structural integrity in high-heat environments. Ideal for components near engines, electronics, or outdoor fixtures.

Dimensional Stability

Low mold shrinkage (0.4–0.7%) guarantees precise, consistent part dimensions during extrusion or injection molding. Reduces post-processing and ensures seamless assembly for complex industrial designs.
