ThermProtect Ampacet’s ThermProtect range of products is part of a portfolio of masterbatches designed to support circular economy initiatives. The ThermProtect range contains a multifunctional stabilizer technology to supply a powerful antioxidant, allowing it to handle materials with challenging levels of post-consumer resin (PCR) content. PCR contaminants such as inks, fillers and catalyst residue can cause viscosity changes, black specks, gels and off-odors that degrade end-product mechanical properties and aesthetics. ThermProtect antioxidants are designed for polyethylene and polypropylene applications, including blow-molded packaging and products, industrial products such as garbage bags and construction products like composite lumber, crates and buckets.

What’s new? ThermProtect 1001145-N, which is used primarily for non-FDA film applications, and ThermProtect 1001265-N, which meets FDA requirements.

Benefits Improved aesthetics, processability and functionality. ThermProtect stabilizes polymers subjected to multiple heat histories and provides thermal stability at high temperatures. It employs specialty radical scavengers, which stop oxidation that can be caused by alkyl radicals, while its acid scavengers eliminate the degrading effects of inks and other contaminants.
