Dupont Kapton PI film / PI tape features

Dupont Kapton PI film / PI tape is a non-meltable polymer, the about body of 1.43 ~ 1.59,24 h baptize assimilation 0.317%. Maintained aural the ambit of -269 ~ 400 ℃. The PI about acclimated for the assembly of films, laminates, molded plastic, cream and Qibu. Biphenyltetracarboxylic dianhydride, diphenylether diamines (R-type) or meta-phenylenediamine (S-type) was obtained. The blur alertness methods: polyamide acerbic beck to casting film, afterwards stretching, the top temperature imidization. The blur chicken transparent, the about body of 1.39 to 1.45, a arresting top temperature, attrition to radiation, actinic attrition and electrical insulation properties, can be acclimated at 250 ~ 280 ℃ air for a long. The bottle alteration temperature were 280 ℃ (Upilex R), 385 ℃ (Kapton), and added than 500 ℃ (Upilex S). The 20 ℃ compactness backbone of 200MPa, 200 ℃ greater than 100MPa. Particularly acceptable for use as a adjustable printed ambit lath substrate and a array of top temperature motor electrical careful materials. From pyromellitic dianhydride (PMDA), and diaminodiphenyl ether (ODA) in the able bread-and-butter dimethylacetamide (DMAC) by polycondensation and salivation deposition, and again by imidization made. is the world's best achievement of the thin-film careful actual has accomplished automated properties, electrical properties, actinic stability, and top radiation resistance, top temperature attrition and low temperature achievement (-269 ℃ to + 400 ° C).

Dupont Kapton PI film / PI tape is of the accomplished calefaction attrition in a polymer actual has been automated species, due to accepting a above all-embracing performance, so can be acclimated as films, coatings, plastics, composites, adhesives, foams, fibers, break blur aqueous clear alignment agents, photoresist has been broadly acclimated in high-tech fields, accepted as a "problem solver". Polyimide blur is a new blazon of top temperature aggressive amoebic polymer film, is from pyromellitic dianhydride (PMDA), and diaminodiphenyl ether (ODA) in the able bread-and-butter dimethylacetamide (DMAC by polycondensation), and salivation film, again by imidization from it is currently the world's best achievement of the blur chic careful actual with accomplished automated properties, electrical properties, actinic adherence and top attrition to radiation achievement , top temperature and low temperature attrition (-269 ℃ to + 400 ° C). 1959 DuPont aboriginal amalgam of ambrosial polyimide, fabricated of polyimide blur (PI film) balloon in 1962, began assembly in 1965, is adapted by a KAPTON article grades. Polyimide blur can be baby accumulation assembly in the backward 1960s, China, is now broadly acclimated in aviation, marine, spacecraft, rocket missiles, diminutive energy, electrical and cyberbanking industries in assorted fields.
