POLYLAC PA-77NB is an ABS High Heat Thermal Stability & Unique Low VOC

CHIMEI POLYLAC™ PA-77NB ABS Resin is a specialized High-Heat ABS Grade developed for Automotive Interior applications where Occupant Comfort, Appearance, and Thermal Stability are critical Requirements. combining Low VOC, Low Emission, Low Odor, and Low Gloss Characteristics, this material is designed to meet the increasingly demanding Standards of Modern Vehicle Interiors.

Unlike Conventional ABS Grades that Focus Primarily on Mechanical Performance, POLYLAC™ PA-77NB Emphasizes Interior Environmental Quality. The Resin is formulated to Minimize Volatile Emissions and Unwanted Odors, helping create a more Comfortable Cabin Environment. These characteristics make it particularly suitable for Enclosed Spaces where material Emissions can directly affect user Experience.

Thermal Durability is Another Key Strength of CHIMEI POLYLAC™ PA-77NB ABS Resin. Engineered with High Heat Stability, the material can withstand the Elevated Temperatures commonly Experienced Inside Vehicle Cabins exposed to Direct Sunlight. This helps Interior components maintain their Appearance, Dimensional Stability, and Mechanical performance throughout Prolonged Service Life.

In addition to its Environmental and Thermal Advantages, POLYLAC™ PA-77NB delivers good Impact Resistance, allowing Interior Parts to Resist Cracking and Damage during Daily use. The Material's Low-Gloss Finish also contributes to a Premium appearance while helping reduce Unwanted Reflections within Vehicle Interiors.

With a Melt Flow Index (MFI) of approximately 10 ML/10 min (ISO 1133), the Resin provides balanced Processing Performance, enabling manufacturers to Mold Complex Interior components while maintaining consistent Quality and Surface Appearance.

Developed by CHIMEI, Taiwan, POLYLAC™ PA-77NB ABS Resin offers a combination of Heat Resistance, Durability, and Low-Emission performance that makes it particularly attractive for Automotive Interior applications where both performance and Passenger Comfort are Important.
