High Temperature Nylon PPA Cov yam ntxwv thiab kev siv tseem ceeb

Cov yam ntxwv ntawm cov khoom siv PPA

1, PPA yog cov khoom siv kub-resistant, nrog melt point ntawm 310-325 ° C thiab kub distortion kub (HDT) ntawm 280-290 ° C.

2, PPA muaj cov roj ua haujlwm zoo thiab ua haujlwm zoo rau ntau yam roj xws li roj roj thiab roj lubricating, txawm tias kub ntawm 150 ℃

3, PPA muaj kev ruaj ntseg zoo heev thiab tsis tshua muaj kev sib ntaus sib tua

4, Kev nqus dej ntawm PPA yog qis dua li ntawm PA6 lossis PA66, thiab nws lub zog tensile tuaj yeem nyob siab dua 80% txawm tias tom qab tau muab tso rau hauv dej txias rau ntau xyoo.

5, PPA muaj huab cua tiv thaiv zoo heev thiab tseem tsim nyog rau kev siv sab nraum zoov mus sij hawm ntev nyob rau hauv huab cua huab cua xws li UV hluav taws xob siab, av noo, thiab kub.

6, PPA muaj kev ua tau zoo ib puag ncig thiab tuaj yeem ncav cuag US FDA qib
