Carboxyl-Terminated Nitrile Liquid Rubber Ctbn 25265-19-4 NBR¹

Product Description Product DescriptionProduct DescriptionCarboxyl-terminated NBR is a kind of low molecular telechelic copolymer with butadiene and AcrylonitriIe as the main chain and carboxyl groups at the end of the molecular main chain, which has fluidity at room temperature.The carboxyl groups at both ends of the main chain of CTBN molecule have high activity, which can be used for chain extension or cross-linking reaction; AcrylonitriIe introduced into the molecular main chain has oil resistance and high temperature resistance, which can promote the polarityThe adhesion of the interface can also improve the properties of blending with thermosetting structural resin, oil resistance and cracking resistance. ApplicationProject nameCarboxyl-terminated polybutadiene acrylonitriIe liquid rubberCTBN-20CTBN-25Viscosity (70oC), pa.s≤20 ≤30Carboxyl content, mmol/g0.46~0.60 0.51~0.65AcrylonitriIe content,%16.0-22.0 22.1-27.0Volatile matter,%≤2.0 ≤2.0EexteriorAmber viscous fluid, no visible impurities.FunctionsCTBN is a toughening modifier for structural resins such as epoxy, phenolic and unsaturated polyester, which can improve the impact strength and peeling strength of the resin. CTBN in aerospace,Weapons and ships, electronic appliances, automobile high-speed rail, petrochemical industry and other fields are widely used for bonding, sealing, spraying, potting and coating, and can also be used as carbon fiber composite rings.Oxygen prepreg toughening agent. Packaging & Shipping PACKAGING50L, 210L or custom packaging.ShippingDuring transportation, rain and humidity should be avoided, and exposure should be prevented.
