GY-PUA SERIES Anti-Hydrolysis Agent in TPU Test Report
GY-PUA SERIES Anti-Hydrolysis agent allows the reaction between carboxylic acid and water, preventing hydrolysis and expanding the lifespan of products.
Description
Intro and Test Purpose
PU is a polymer material with unique traits. It combines the properties of plastic, elastomer, and coating such as excellent hardness, strength, anti-abrasion, vibration absorption, anti-radiation, permeability resistance, and processability. PU has a wide range of applications, including PU foam, PU elastomer, PU waterproof material, PU coating, PU adhesive, PU biomedical material, etc.
However, the structure of PU consists of repetitive carbamate groups. The carbamate groups are very sensitive to humidity and heat, causing the scission of the molecular chain. GY-PUA SERIES Anti-Hydrolysis agent allows the reaction between carboxylic acid and water, preventing hydrolysis and expanding the lifespan of products.
Test Result
Conclusion
GYC Group is the leading manufacturer of fine chemical and functional additives in Asia. With almost 40 years of experience in the chemical industry, GYC provides total solutions to general plastic and industrial plastic.
Compare TPU with added GY-PUA SERIES and normal TPU, the latter experienced drop of tensile strength after 3 days. Both TPU with 0.5 phr and 1 phr hydrolysis agent experience slower and steadier drop, indicating that adding hydrolysis agent in TPU improves the tensile strength significantly.
