Hirose Paper Co., Ltd.'s PPS fiber 100% wet non-woven fabric "PS type" uses PPS (polyphenylene sulfide), a super engineering plastic. This material has a very high heat resistance with a melting point of 280°C and a maximum continuous use temperature of 200-220°C, which is superior compared to other polymers such as PET and PE. This characteristic makes it ideal for use in the energy and mobility sectors, where stable performance is required in high-temperature environments. Additionally, PPS has heat resistance similar to PTFE, a type of fluorinated compound (PFAS), contributing to the reduction of environmental impact. Furthermore, the PS type can be processed into thicknesses ranging from 29 to 195 μm, accommodating various applications. *For more details, please refer to the PDF document or feel free to contact us.*

Hirose Paper Co., Ltd.'s PPS fiber 100% wet non-woven fabric "PS type" uses PPS fibers with excellent chemical resistance.

In thermal design under high-temperature environments, the "deformation and deterioration" of materials poses a significant risk of serious troubles. Hirose Paper's PPS non-woven fabric (PS type) is a wet non-woven fabric made from 100% PPS fibers, demonstrating high heat resistance with a melting point of 280°C. Even when exposed to high temperatures for extended periods, it is less likely to undergo dimensional changes, enabling stable thermal control design. Additionally, PPS has resistance to many organic solvents and alkalis. Compared to polymers such as PET and PE, it exhibits higher resistance to organic solvents and alkalis, making it a noteworthy alternative material to PTFE in terms of chemical resistance. *For more details, please refer to the PDF document or feel free to contact us.*
