polyterpene resin

Polyterpene Resin Description: Polyterpene resin, also named polyterpene or pinene resin. It is a series of linear polymer which primarily use of turpentine α - pinene or β - pinene that Falk's catalytic role, then by the cationic polymerization from liquid to solid.Performance characteristic: Polyterpene resin transparent is light yellow, brittle thermoplastic solid. Nontoxic, odorless, radiation resistance, anti-crystallization . relatively stable for Oxygen, heat, and light; A good compatibility of various compounds; resistant acid, diluted alkali; viscosifying strong, strong electric insulation, do not dissolve in water and ethanol.Specification: Type Polyterpene ResinSoftening point (R&B) , 80--125Color (Fe-Co Scale) ,≤ 4Acid numbermgKOH/g),≤ 0.5Saponification valuemgKOH/g),≤1.0Iodide numbergi/100g) 40--65Molecular weight 1200 1300Ash weight 0.005%
