Rhenogran® P91-40/NR

Technical Datasheet | Supplied by Lanxess
40% aramid fiber pulp predispersed in 60% NR polymeric binder with additives. Acts as a reinforcing agent. It improves elasticity modulus, modulus at low strain, compression resistance, flexural strength, hardness, dimensional stability, abrasion, tear and penetration resistance, shrinkage and creep resistance. Also enhances the green strength of the uncured compound depending on the dosage. Compatible with NR, SBR. Recommended for molded and extruded articles, e.g. hoses, V-belts, seals, rollers and tires. The dosage rate is 2-20 phr.
