BTWR 500

Supplied byNanjing Baitong New Material- Last Updated on Nov 10, 2025

BTWR 500 by Nanjing Baitong New Material is an anti-hydrolysis agent. It can significantly extend the service life of materials, enhance stability and inhibit the formation of carboxylic acids in hydrolysis reactions. It improves weather-, UV- and water resistance and reduces cracking or aging caused by hydrolysis.
  • It maintains the mechanical properties (e.g. tensile strength, toughness) and processing stability of polymers in harsh environments such as humidity, heat, acid and alkali or UV irradiation.
  • It extends the life of the material by more than 3 times, which is especially suitable for recycling scenarios of recovered materials.
  • BTWR 500 is mainly used for easily hydrolyzed polymer materials, such as plastics and elastomers (PET, PBT, PA (nylon), TPU, TPEE, PLA, PBAT, EVA, etc.), automotive industry, electronic component and food packaging.
  • It has recommended dosage level of 0.1-1 phr.
