Rhenogran P91-50/Q Aramid fibre pulp Rhein Chemie Fibers >> Aramid Rubber - Elastomer (Chloroprene, Butyl …) Silicones (Si) SEALANT Rhenogran® P91-50/Q Predispersed aramid chopped fibre pulp for reinforcing silicone rubber compounds 50% aramid fibre pulp(Type: Twaron®)* 50% silicone binder Rhenogran P91-50/Q is made of aramid fibre pulp (type: Twaron®) which is predispersed in a polymeric binder. Rhenogran P91-50/Q is used as a high-grade reinforcing material for silicone rubber compounds. Depending on the amount added (usually 4-20 phr), using Rhenogran P91-50/Q enhances important technical rubber properties: the dimensional stability and green strength of the uncured compound. The vulcanizing rate is usually not affected. Various physical properties of vulcanized rubber compounds, such as elasticity modulus, modulus at low strain, compression resistance, flexural strength, hardness, abrasion, t ear propagation resistance, penetration resistance, shrinkage and creep resistance, are also significantly improved, sometimes many times over. Usually 2-20 phr Moulded and extruded articles, hose, V-belts, seals, conveyor belting, rollers, etc. based on silicone rubber. Aramid chopped fibre pulp predispersed in a polymeric binder. Used as a high-grade reinforcing material for silicone rubber compounds for moulded and extruded seals. Enhances dimensional stability and green strength. Improves elasticity modulus, modulus at low strain, compression resistance, flexural strength, hardness, abrasion, tear propagation resistance, penetration resistance, shrinkage and creep resistance. Use level: 2-20 phr.
