| Pentrex G |
 |
Pentrex G is a pentaerythritol ester of rosin which provides superior tackifying action to synthetic and natural rubber applications.
Highly compatible with the more non-polar elastomers like EPDM, butyl, natural and SBR.
The maleic modification aids EPDM tack and adhesion properties.
Pentrex G may be used to:
- provide building tack for ply-up applications
- provide wetting action for filler/rubber
- speed up incorporation time of mineral fillers
- provide cohesion of the compound matrix
- reduce compound viscosity at process temperatures
- reduce "nerve" for natural rubber compounds
- improve rubber to metal/fibers interaction/bonding
- provide tackifying action for adhesives and hot melts
Pentrex G may effectively be used as an economic alternative to "C5 type", terpenes and various other tackifying resins.
Dosages range from 5 to 30 phr for highly loaded compounds. Pentrex G is approved for use in FDA applications per Section 177.2600, CFR Title 21. |
