Functional Materials

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

Properties List

  • PET flowability improvement

  • PET crystallization acceleration

  • Maintains the molecular weight of PET (does not lower the IV value)
