Pibiflex® 4054 IM NERO
Supplied bySO.F.TER. (Celanese)- Last Updated on Dec 4, 2018
Pibiflex® 4054 IM NERO is a thermoplastic copolyester grade formed by rigid crystalline PBT segments and soft amorphous long chain polyether segments. The soft segments provide elasticity and rubber-like properties, while the hard segments provide the processing ease and the strength typical of engineering plastics. Is suitable for processing by injection molding. Exhibits excellent toughness, elasticity, high creep resistance, impact strength, flexural fatigue resistance, good flexibility at low temperatures, good retention of characteristic at high temperatures and outstanding chemical resistance (to fuels, oils, greases). Shows good adhesion properties to many polymeric materials including ABS, PBT, PC, PC/PBT, PC/ABS, EVA, SEBS, TPU and to many paints, glues and metals. Is fully recyclable material and it can be reused after regrinding. Used in automotive, electrical appliances, industrial and sports application. Is approved for automotive applications by the most important automotive manufacturers and Tier 1.
