[0002] Thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, is a type of linear block copolymer containing PBT (polybutylene terephthalate) polyester hard segment and aliphatic polyester or polyether soft segment. It has both the excellent elasticity of rubber and the easy processability of thermoplastic plastics, with adjustable hardness and design freedom. It is a new variety of thermoplastic elastomer that has attracted much attention.

[0003] During the processing of thermoplastic polyurethane elastomer, a drying filter is required to dry and filter the thermoplastic polyurethane elastomer. The existing drying filter for thermoplastic polyurethane elastomer has some defects during use. The drying effect is not good during the drying process. During the filtration stage, the filtration effect is poor and the screened debris is not easy to be discharged, which affects the processing quality of the thermoplastic polyurethane elastomer.
