Pentrex G Pentaerythritol ester of rosin Akrochem Tackifier >> Rosin ester >> Penthaerythritol (penta) ester Rubber - Elastomer (Chloroprene, Butyl …) ADHESIVE >> Hot-melt 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 Pentaerythritol ester of rosin. Provides superior tackifying action to synthetic and natural rubber applications for adhesives and hot melts. Highly compatible with the more non-polar elastomers like EPDM, butyl, natural and SBR. Provides wetting action for filler/rubber, speed up incorporation time of mineral fillers, cohesion of the compound matrix. Reduces compound viscosity at process temperatures. Improves rubber to metal/fibers interaction/bonding.
