About product

Polyether pu is more resistant to hydrolysis and generally has lower glass transition temperature, while polyester pu has better resistance to oils and fuels. thermoplastic polyurethane (tpu) tpu's contain linear flexible coiled and rigid packaged segments, able to merge without degradation of urethane links.
Our thermoplastic polyurethanes (tpu) can be processed on standard equipment for the processing of thermoplastics. the most frequently used techniques for processing tpu are injection molding, extrusion and blow molding.
The tpu was modified by reactive extrusion in a co-rotating twin-screw extruder zsk 30 (werner & pfleiderer, germany). the screw extruder has an l/d ratio of 41. a low shear screw adapted for polyurethane thermoplastic processing was used. the machine
