PET-PE Compatibilizer
Description
A reactive compatibilizer for PET-PE blends — a polyolefin grafted with maleic anhydride or glycidyl methacrylate, with functional groups that bond to the terminal -OH/-COOH groups of PET. It reduces phase separation in PET-LDPE/PE blends (a typical problem when processing rPET contaminated with film and cap residues) and improves the low-temperature performance and impact strength of the final material. Suitable for injection molding and extrusion pelletizing of rPET.
Key properties
- Reactive PET-PE compatibilizer with functional groups
- Reduces phase separation in PET blends with LDPE/HDPE
- Improves low-temperature performance and impact strength of the final material
- Improves melt homogeneity and flowability
- Compatible with injection molding and extrusion pelletizing
- Typical dosage 2-5% by weight of PET
Applications
PET recycling (rPET). Compounding of recycled PET with polyolefin residues (from caps, labels, films) — allows processing of PE-contaminated rPET streams without separation.
PET fiber and engineering grades. Production of impact-resistant PET compounds for technical parts.
Roofing and geomembrane materials. PET-PE blends for waterproofing.
Automotive and electronics. Impact-modified PET-PE compounds for under-hood parts and electronics housings.
