Kazhinji inogadzirwa kubva kuTPU tambo, inoshandiswa senge simba rekubatanidza kudzora kufamba kwenharembozha. Inobvumira kukurumidza kudzokororwa uye inoshandiswa zvakanyanya mumotokari, muchina, zviridzwa, uye zvimwe nharembozha. Zvitubu zvinoiswa muzvikamu zvichienderana negwara, zvikuru kuruboshwe-kuruoko nekurudyi{3}}makoiri zvitubu.
Nezvinhu, ivo vanonyanya TPU uye PVC chitubu waya. TPU spring wire inopa kunonoka kwemoto, kuramba mafuta, asidhi uye alkali resistance, yakaderera-temperature resistance, UV resistance, abrasion resistance, uye hydrolysis resistance. PU iri kuwedzera kushandiswa seyakafarirwa zvinhu zvechirimo waya.
