Description and Uses

4,4'-oxybisbenzoic acid is a monomeric liquid crystal polymer. it is used widely in the electronics and pharmaceutical industries. Preparation of whole Polyarylate thermoplastic liquid crystal polymer (TLCP), also can be used to prepare high strength, high modulus of liquid crystal fibers, specialty plastics and polymer flame retardants in industrial. also as a non-liquid crystal polymer additives, reduce baking temperature and viscosity of the polymer to facilitate processing and made of an insulating material.
