Ultra-High Flow Efficiency

POLYLAC PA-756H’s unmatched flowability (80 MFI) fills intricate molds effortlessly, reducing cycle times by 15–20%. Perfect for complex geometries like thin-walled laptop casings or automotive grilles, minimizing warping and material waste.

Strength Meets Impact Resistance

With 45 MPa tensile strength and 8 KJ/m² impact resistance, this Chimei POLYLAC ABS withstands stress and drops. Use it for tool handles, appliance housings, or rugged equipment parts that demand toughness without brittleness.

Heat Resistance for Demanding Environments

Vicat softening at 102°C and heat distortion up to 97°C ensure stability in high-temperature settings. Ideal for under-the-hood automotive components or electronics exposed to heat, preventing deformation during operation.

Applications

Automotive: Ultra-thin trim panels, large dashboards, and vent housings with zero sink marks.
Electronics: Slim smartphone frames, lightweight laptop bases, and wearables requiring precise thin-wall molding.
Appliances: Large refrigerator components or vacuum cleaner bodies needing high flow for seamless finishes.
Industrial Equipment: Complex connectors and housings where fast cycle times reduce production costs.
