Kedu ihe bụ TPU?

Thermoplastic polyurethane (TPU) bụ ụdị plastik pụrụ iche emepụtara mgbe mmeghachi omume polyaddition na-eme n'etiti diisocyanate na otu diol ma ọ bụ karịa. Nke mbụ mepụtara na 1937, polymer a na-agbanwe agbanwe na-adị nro ma na-edozi ya mgbe ọ na-ekpo ọkụ, na-esi ike mgbe ọ dị jụụ ma nwee ike ịmegharị ya ọtụtụ ugboro na-enweghị atụfu iguzosi ike n'ezi ihe. Ejiri ya mee ihe dị ka plastik injinia malleable ma ọ bụ dị ka onye na-anọchi anya rọba siri ike, a ma ama TPU maka ọtụtụ ihe gụnyere ya: elu elongation na tensile ike; elasticity ya; na ogo dị iche iche, ikike ya iguzogide mmanụ, griiz, ihe mgbaze, kemịkalụ na abrasion. Njiri mara ndị a na-eme TPU ewu ewu n'ofe ahịa na ngwa dị iche iche. Na-agbanwe agbanwe, enwere ike ịpụpụ ya ma ọ bụ ịgbanye ya na ngwa nrụpụta thermoplastic iji mepụta ihe siri ike na-abụkarị maka akpụkpọ ụkwụ, eriri & waya, eriri na tube, ihe nkiri na mpempe akwụkwọ ma ọ bụ ngwaahịa ụlọ ọrụ ndị ọzọ. Enwere ike ịgbakọta ya iji mepụta ịkpụzi plastik siri ike ma ọ bụ hazie ya site na iji ihe mgbaze organic iji mepụta akwa akwa, mkpuchi mkpuchi ma ọ bụ nrapado na-arụ ọrụ.
