ROSIN ESTER :

* PENTAERYTHRITOL ESTER #1020

Pentaerythritol Ester with multiple formed (flake and lump), specially stabilized and treated more than natural rosin to give color stability at elevated temperatures and will exhibit adhesion properties.

Excellent solubility in Xylene, Toluene, other aromatic and aliphatic hydrocarbon solvent. Also good solubility in esters and ketones.
Compatibility in EVA, SIS, natural and chlorinated rubber.
