Huanyuchang is committed to becoming a substrate, semiconductor materials first-class integrated service provider, the company 's core business is to provide customers with high cost-effective consumables materials, solve the pressing, off-type application material solutions.
Huanyuchang has a R & D team composed of university members, focusing on the development of FPC / PCB high-performance composite, hot-pressed materials.
The thickness of high temperature resistant matte film is 30 um, 35 um and 50 um, which is processed by PET modified film with high temperature resistant additives. The product has good high temperature resistance. There is no residue on the surface of the high temperature resistant matte film after pressing, which is added for the design and manufacture of flexible and rigid circuit boards.

The thermal stability limit of high temperature resistant matte film is a function of time and temperature. Under the combined action of the two, thermal recession will occur when the performance of the film is exceeded. The characteristic of this decline is to make the film brittle, brown, and then carbonized. In general, the thermal degradation of the film above 250 ° C will be quite rapid, so the application value of the related isolation of the high temperature release film is limited, and the one-time use effect is the best.
