LCP A115 A130 A435 E440i S475 耐高温 低翘曲 (CAS No.None)

Product Name:Vectra® LCP A115 A130 A435 E440i S475 High Temperature Low Warpage

English Name:Vectra® LCP A115 A130 A435 E440i S475 High Temperature Low Warpage

CAS No.:81848-68-4

Aliases:Liquid Crystal Polymer, LCP Resin, High Temperature LCP

Molecular Formula:(C7H4O2)x(C11H6O2)y

Physical Properties:This product is a thermotropic liquid crystal polymer composed of rigid rod-like macromolecules that align in an ordered liquid crystalline structure in the molten phase. The continuous operating temperature is up to 240°C and short-term up to 340°C. It exhibits extremely low heat of fusion, enabling shortened injection molding cycle times. Dimensional stability is excellent with achievable tolerance class of T6. Flash-free injection molding is possible. Tensile strength reaches up to 200 MPa and tensile modulus up to 30,000 MPa. The coefficient of thermal expansion is extremely low, comparable to steel and ceramics. It is inherently flame retardant, meeting UL 94 V-0 (5VA for some grades). Halogen-free and additive-free. Resistant to chemicals and oxidation.

Uses:Suitable for electronic components such as connectors, sockets, switches, bobbins and chip carriers, as well as medical devices including sterilizable trays, dental tools and surgical instruments. It is also used in industrial parts such as pumps, instruments and valve liners. Unfilled grades can be extruded into films or sheets for barrier packaging, or melt-spun into high-performance fibers and yarns.
