Technical Datasheet | Supplied by Celanese
Vectra® E440I WHITE is a white colored, halogen-free, highly crystalline, thermotropic, self-reinforcing, low warp, non-flammable, inherently flame retardant liquid crystal polymer (LCP) grade reinforced with glass/mineral. It forms a carbon char layer, retarding the development of flammable gases, under high flame temperature. Exhibits scratch-, abrasion-, excellent creep- and corrosion- resistance, outstanding rigidity, stiffness, very low heat fusion, excellent mechanical properties, toughness & strength, excellent property retention at cryogenic temperatures and offers time & money savings as well as longer pan life. Has smooth surface appearance, low moisture absorption, very low coefficient of thermal expansion, low smoke generation, excellent dielectric properties, withstands gamma ray sterilization inertness, non-toxicity and bio-inactivity. It creates thin-walled complex components that demand dimensional stability, chemical resistance, solvent resistance and good tensile & impact strength. Also exhibits easy flow, little or no shrinkage in the flow direction, excellent flex/fold characteristics, good vibration damping characteristics & shock absorbency and requires very little time to set-up or solidify. Is suitable for processing by injection molding. Potential applications include aerospace & defence, building & construction, consumer goods and oil, gas & mining. Also used in automotive & transportation, electrical as well as electronics, energy, industrial and textiles, fibers & filtration. Complies with ROHS, FDA, PFOS and PFOA.
