Description:
PCT polyester resin is a kind of based on aggregation (ring hexamethylene - 2 methylene of benzene 2 hydrochloride) chemical characteristics of the high temperature polyester.It besides having engineering polyester (such as PET and PBT) good resistance to chemical corrosion resistance, machinability and size stability, PCT polyester resin also have heat resistance, make it especially suitable for the demanding applications, such as cars and electrical/electronic industry, etc.PCT polymer easy to processing, the product has a variety of processing properties, excellent thermal stability, short cycle time and erosion of mold.Its melting point is 250 ℃, crystal color is dark yellow, often join the glass fiber used.PCT high temperature polymer ability, can withstand the surface installation process steam and infrared reflow welding, products with good ductility and toughness.Because of the improved heat resistance, rapid molding cycle and excellent machinability, PCT polyester resin with excellent performance and cost performance.
application:
electrical insulating materials, transparent conductor, switch, spool, automobile industry, such as automobile relay, connectors, pharmaceutical fields, such as medical apparatus and instruments, goggles, safety cover, also can be used as optical fiber, high capacity of flexible fiber, safety signs, amusement facilities, etc
