Melting point 280℃ / Maximum continuous use temperature 200-220℃ PPS non-woven fabric
PS Series
Exhibits excellent performance in heat resistance (melting point 280°C, maximum continuous use temperature 200-220°C) and flame retardancy (high self-extinguishing property with LoI=34)!
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.*
