Si-TPV 3400-55A Thermoplastic Elastomer
piav qhia:
SILIKE Si-TPV 3400-55A thermoplastic elastomer yog dynamic vulcanized thermoplastic silicone raws li elastomer uas ua los ntawm cov cuab yeej tshwj xeeb tshaj plaws los pab cov roj hmab silicone dispersed hauv TPU tusyees raws li 2 ~ 3 micron particles nyob rau hauv microscope. Cov ntaub ntawv tshwj xeeb sib xyaw ua ke lub zog, toughness thiab abrasion tsis kam ntawm cov thermoplastic elastomer nrog cov khoom tsim nyog ntawm silicone: softness, silky xav, UV teeb thiab tshuaj tiv thaiv uas tuaj yeem siv dua thiab rov siv dua hauv cov txheej txheem tsim khoom.

Cov txheej txheem txheej txheem no yuav txawv nrog cov cuab yeej thiab cov txheej txheem.
● Kev ua haujlwm thib ob
Raws li cov khoom siv thermoplastic, cov khoom siv Si-TPV tuaj yeem ua tiav rau cov khoom lag luam zoo tib yam
● Txhaj Molding Siab
Kev tuav lub siab feem ntau nyob ntawm qhov geometry, thickness thiab qhov rooj qhov chaw ntawm cov khoom. Lub siab tuav yuav tsum tau teem rau tus nqi qis thaum xub thawj, thiab tom qab ntawd maj mam nce kom txog thaum tsis muaj qhov cuam tshuam txog kev pom ntawm cov khoom txhaj tshuaj molded. Vim yog cov khoom elastic ntawm cov khoom, ntau lub zog tuav yuav ua rau muaj kev deformation loj ntawm lub qhov rooj ntawm cov khoom.
● Rov qab siab
Nws raug pom zoo tias lub siab rov qab thaum lub ntsia hlau thim rov qab yuav tsum yog 0.7-1.4Mpa, uas yuav tsis tsuas yog ua kom muaj kev sib luag ntawm cov yaj yaj, tab sis kuj xyuas kom meej tias cov khoom tsis raug degraded los ntawm shear. Qhov pom zoo ntsia hlau ceev ntawm Si-TPV yog 100-150rpm los xyuas kom meej qhov ua tiav melting thiab plasticization ntawm cov khoom tsis muaj cov khoom degradation los ntawm shear cua sov.
Lus Cim:
1. Si-TPV elastomer cov khoom tuaj yeem tsim tau siv cov txheej txheem thermoplastic manufacturing txheej txheem, suav nrog overmolding lossis co-molding nrog yas substrates xws li PP, PA.
2. Kev xav zoo heev ntawm Si-TPV elastomer tsis tas yuav tsum tau ua cov txheej txheem ntxiv lossis txheej txheej.
3. Cov txheej txheem txheej txheem yuav txawv nrog cov khoom siv thiab cov txheej txheem.
4. Lub desiccant dehumidifying ziab yog pom zoo rau txhua qhov ziab.
Pob:
25KG / hnab, khoom siv tes ua hnab nrog PE puab lub hnab.
Txee lub neej thiab kev cia khoom:
Thauj raws li cov tshuaj tsis muaj teeb meem. Khaws rau hauv qhov chaw txias thiab zoo ventilated.
Cov yam ntxwv qub tseem nyob ruaj khov rau 12 lub hlis txij li hnub tsim khoom yog tias khaws cia hauv kev pom zoo cia.
