Elastomer Thermoplastic (TPE) jẹ polima rirọ ti awọn ohun-ini imọ-ẹrọ jẹ eyiti o ni ibatan pẹlu lile ti ohun elo funrararẹ (ti o wa lati Shore A si Shore D) ati awọn abuda rẹ ni awọn agbegbe oriṣiriṣi tabi awọn ipo iṣẹ. Awọn ohun elo TPE le pin si ọpọlọpọ awọn oriṣi.
1. Polyether block amide (PEBA)
O jẹ elastomer polyamide ti ilọsiwaju pẹlu awọn ohun-ini to dara gẹgẹbi rirọ, irọrun, imularada iwọn otutu kekere, resistance abrasion ati resistance kemikali. Dara fun awọn ohun elo ni awọn ọja imọ-ẹrọ giga.
2. roba thermoplastic roba (SBS, SEBS)
O jẹ polymer thermoplastic ti ara ẹni. Awọn elastomers SBS ati SEBS jẹ lilo pupọ julọ lati ṣe ọpọlọpọ awọn ọja ti o nilo rirọ, ifọwọra asọ ati aesthetics. Wọn jẹ o dara fun lilo ninu awọn agbekalẹ aṣa ti a ṣe apẹrẹ fun awọn ọja pato. Ti a fiwera pẹlu SBS, SEBS n ṣe dara julọ ni awọn ohun elo kan pato nitori pe o daraju ifoyina ti awọn egungun ultraviolet dara julọ, ati iwọn otutu ṣiṣiṣẹ rẹ paapaa le de 120 ° C; SEBS le ti ni apọju ati thermoplastic (PP, SAN, PS, ABS, PC-ABS, PMMA, PA) ti wa ni adalu lati pade awọn ibeere apẹrẹ ti aesthetics tabi iṣẹ-ṣiṣe.
3. polyurethane ti thermoplastic (TPU)
O jẹ polima ti iṣe ti polyester (polyester TPU) ati awọn idile polyether (polyether TPU). O jẹ elastomer pẹlu resistance yiya giga, resistance abrasion ati resistance gige. ). Iwa lile ọja le wa lati 70A si 70D Shore. Ni afikun, TPU ni agbara ti o dara julọ ati pe o le ṣetọju awọn abuda ti o dara paapaa labẹ awọn iwọn otutu to gaju.
4. Thermoplastic vulcanizate (TPV)
Awọn akopọ ti polymer pẹlu roba elastomer (tabi roba ti o ni asopọ agbelebu). Ilana vulcanization / crosslinking yii jẹ ki TPV ni thermoplasticity ti o dara julọ, rirọ ati irọrun.
