Rhenogran P91-40/NR Aramid fibre pulp Rhein Chemie Fibers >> Aramid Rubber - Elastomer (Chloroprene, Butyl …) SEALANT Rhenogran® P91-40/NR Predispersed aramid short fibre pulp for reinforcing natural, synthetic and thermoplastic rubber compounds 40% aramid fibre pulp (Type: Twaron® 1091)* 60% NR binder and additives Rhenogran P91-40/NR is made of aramid fibre pulp (type: Twaron®) which is predispersed in a polymeric binder. Rhenogran P91-40/NR is used as a high-grade reinforcing material for sulphur- and peroxide-cured rubber compounds and in thermoplastic rubbers, preferably based on NR, SBR. Depending on the amount added (usually 2-20 phr), using Rhenogran P91-40/NR 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, tyre compounds etc. based on NR, SBR; Rhenogran P91-40/NR may also be used in other elastomers. Aramid short fibre pulp predispersed in a polymeric binder. Used as a high-grade reinforcing material for sulphur- and peroxide-cured rubber compounds and in thermoplastic rubbers, preferably based on NR, SBR 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.
