Chlorinated Polyolefin/Chlorinated EVA

Polypropylene(PP) is a resin which is widely used for film, molded products and for other useful products. Due to its low polarity and high crystallinity, it is difficult to adhere. SUPERCHLON® is one of the few products which can easily adhere to polyolefins. SUPERCHLON® is thermoplastic resins with a chlorine content of less than 45% that can be dissolved well in organic solvents. Substantial R&D investment has provided a continuous stream of new products to meet the ever challenging need for the coating, ink and adhesive industries.

General Characteristics

Appearance	Clear - Pale yellow, pellets or viscous liquid (Chlorinated EVA)
Solvent	Toluene (Chlorinated EVA)
Dry film	Clear, transparent and flexible
Solubility	Generally soluble in aromatic hydrocarbons
Viscosity	Depends on the chlorine content and the degree of molecular weight
