AddWorks® ATR 146, Clariant’s New Light & Heat Stabilizer

This is a Past Webinar
Plastics for the automotive industry have to fulfil more and more stringent requirements. Many challenges have to be overcome in automotive interiors, especially for polypropylene based filled compounds (TPO), representing about 50% of the plastics in vehicle interiors. Among those is to combine heat and light stabilization with low emissions and low odor impact.

TPO compounds are emitting volatile organic compounds (VOC) that could bring an unhealthy cabin environment, they usually require higher concentration of phenolic antioxidant or addition of sulfur-based co-stabilizer for stabilization against heat exposure, these compounds can cause undesirable odors.

AddWorks® ATR 146 is Clariant’s new low dosage, sulfur-free stabilizer solution for filled TPO compounds used in automotive interior. It offers outstanding light protection, exceptional heat stability, and reduced VOC/odor emissions in one single solution, fulfilling current OEM requirements and setting the benchmark for the next generation of automotive interiors.
