ABS PA-77NB Low-voc, high-heat-resistant ABS specifically designed for automotive interior parts

Taiwan Chi Mei Polylac® PA-77NB heat-resistant low-VOC ABS resin

Model: PA-77NB

Form: Off-white granular, density 1.05 g/cm³ (ISO 1183,23 ℃)

Packaging: 25kg per bag (original factory standard packaging)

Low VOC environmental friendliness: Complies with the VOC emission standards for automotive interiors (such as GB/T 27630-2011), and has no irritating odor.

Heat resistance: The heat distortion temperature (HDT) reaches 106℃ (after annealing, 1.8MPa, ASTM D648), and it is stable under high-temperature working conditions.

High fluidity: Melt index 10 cm³/10min (220℃/10kg, ISO 1133), suitable for rapid injection molding of complex thin-walled parts.

Low shrinkage rate: The molding shrinkage rate is 0.3%-0.6% (ASTM D955), with high dimensional accuracy and reduced post-processing costs.

Safety certification: UL94 HB flame retardant grade (1.5mm thickness), RoHS/REACH compliance.

Environmental compliance challenge: Pass VOC testing (benzene/aldehyde substance content ≤0.05mg/m³) to meet the export requirements of automotive interiors.

Improved production efficiency: High fluidity shortens the injection molding cycle by 15%, making it suitable for mass production.

Cost control: Compared with PC/ABS, the unit price of PA-77NB is 15% lower and the processing energy consumption is reduced by 10%.
