Product Description

GY-HP-70 is a high-performance thermal anti-yellowing additive specially developed for plastics,

engineering polymers, resin systems, rubber, adhesives, and electronic materials.

It effectively prevents or delays yellowing, oxidation, and thermal aging caused by high-temperature processing,

while maintaining polymer physical properties and extending product service life.

With excellent compatibility and high thermal stability, GY-HP-70 is particularly suitable for epoxy resin,

PU, engineering plastics, and electronic cleaning applications.
