Product Detail

Khoom cim npe

Polyphthalamide (aka. PPA, High Performance Polyamide) yog ib feem ntawm thermoplastic hluavtaws resins nyob rau hauv polyamide (nylon) tsev neeg txhais tau tias thaum 55% los yog ntau dua moles ntawm carboxylic acid ib feem ntawm lub rov qab unit nyob rau hauv lub polymer saw yog tsim los ntawm ib tug ua ke. terephthalic (TPA) thiab isophthalic (IPA) acids. Kev hloov pauv ntawm aliphatic txiav txim siab los ntawm aromatic txiav txim siab nyob rau hauv cov pob txha polymer tsub kom lub melting point, iav hloov kub, tshuaj tiv thaiv thiab nruj.

PPA raws li cov resins yog molded rau hauv qhov chaw los hloov cov hlau nyob rau hauv daim ntawv thov uas yuav tsum tau kub kub kuj xws li automotive fais fab tsheb ciav hlau Cheebtsam, lub tsev rau kub kub hluav taws xob connectors thiab ntau lwm yam kev siv.

Lub iav hloov pauv kub ntawm PPA nce raws li qhov nyiaj ntawm TPA nce. Yog tias ntau tshaj 55% ntawm cov kua qaub ntawm PPA yog tsim tawm ntawm IPA, ces cov copolymer yog amorphous. Cov khoom ntawm semi crystalline polymers v amorphous polymers tau piav qhia nyob rau lwm qhov. Luv luv, crystalline pab nrog cov tshuaj tiv thaiv thiab cov khoom siv kho qhov muag saum lub iav hloov kub (tab sis hauv qab lub ntsiab lus melting). Amorphous polymers zoo nyob rau hauv warpage thiab pob tshab.

Cov yam ntxwv ntawm PPA

PPA cov khoom muaj kev sib xyaw ua ke zoo heev, uas ua tau zoo ntawm thermal, hluav taws xob, lub cev thiab tshuaj lom neeg. Tshwj xeeb tshaj yog nyob rau hauv siab kub PPA tseem muaj siab rigidity thiab siab zog, ua ke nrog zoo heev dimensional raug thiab stability.
