Description

technical field

[0001] The invention relates to a PBT composite material, in particular to a high CTI value halogen-free flame-retardant reinforced PBT composite material and a preparation method thereof. Background technique

[0002] Polybutylene terephthalate (PBT), also known as polytetramethylene phthalate, is a thermoplastic engineering plastic. Polybutylene terephthalate is crystalline, with a melting point of 224°C, a relative density of 1.31-1.55, and one of the lowest water absorption rates among thermoplastics. It has excellent toughness, fatigue resistance, impact strength, and natural Lubricity and wear resistance, small friction coefficient, but high notch sensitivity; good heat resistance, weather resistance, flame resistance, but slow burning; good dimensional stability, excellent electrical properties, good arc resistance. Polybutylene terephthalate molding can be injection molding, extrusion, blow molding, coating, welding, bonding, machining, vacuum formin...
