Polyester toughener & Polyester-based alloys compatibilizer

Description

Fine-Blend® SOG-03 is a glycidyl methacrylate grafted polymer with high reactivity and low residue. The base polymer is a polyolefin elastomer. It has semitransparent pellet appearance.
SOG-03 can be completely used as substitute for EMA-co-GMA and EBA-co-GMA in PBT and PBT alloys, and also shows a better thermal stability and processability.
