PET Modifier A-51, A-55
PET modifier A-51 and A-55 are solid ester oligomers developed for the purpose of improving the melt flow characteristics of PET resins.
Polycizer A-55 increases A-51's intrinsic viscosity and decreases volatile components.
Features
Effective for Improving PET Flowability & Accelerating PET Crystallization, An Easily Handled Solid Modifier
- Two types of products, A-51 and A-55
- Effective for improving flowability of PET, PET/pigments, PET/glass fibers
- As a mold processing aid, effective for improving yields
- Widens the temperature range where PET crystallization begins, effective for reducing cycles and saving energy during sheet film production and injection molding
- Maintains the molecular weight of PET (does not lower the IV value)
- A solid modifier that makes mixing in a dry blend possible
Major Applications
- Modifier for PET/glass fiber or its masterbatch
- Modifier for PET/pigments or its masterbatch
- PET sheets
- Solar cell back sheets
