The natural and synthetic resins produced by the HARRPA members are introduced in the compositions based on rubbers (as natural rubber or SBR) and/or thermoplastic elastomers ( as styrene block copolymer or EPDM). Indeed, the low molecular weight polymers with a high softening point (in general) have an excellent compatibility with a variety of nonpolar or polar elastomers.

Thanks to this degree of compatibilization, the introduction of our resin products in rubber and thermoplastic elastomer compounds enables to:

Applications: rubber compounds for Tire and Mechanicals Rubber Goods (hose, belts, …), shoe sole, and floors.

Resins (like rosin soaps) are also used as processing aids in few elastomer production.
