The "PS type" is a wet non-woven fabric made from 100% PPS fiber (polyphenylene sulfide). It demonstrates excellent performance in heat resistance, steam heat resistance, chemical resistance, thermal insulation, and flame retardancy, making it suitable for filter substrates for water, oil, and air, as well as tape substrates. Additionally, it shows excellent hydrolysis resistance to steam, maintaining over 90% strength retention even at 160°C in an autoclave. 【Features】 ■ Heat resistance ■ Thermal insulation ■ Steam heat resistance ■ Flame retardancy ■ Chemical resistance *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 (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. This material has high resistance to many organic solvents and alkalis, outperforming other polymers such as PET and PE. Specifically, it demonstrates stable performance against chemicals such as acetone (100%, 20°C), benzene (100%, 20°C), and chloroform (20%). This characteristic makes it ideal for use in harsh chemical environments such as chemical plants and manufacturing sites. Additionally, the PS type is available in basis weights of 16 to 106.2 g/m² and thicknesses of 29 to 195 μm, accommodating a variety of 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 fiber with excellent steam resistance. This material has outstanding hydrolysis resistance against high-temperature steam and retains over 90% of its strength even after being treated in an autoclave at 160°C for 24 hours. This characteristic makes it ideal for use in high-temperature and high-humidity environments, as well as in the medical field where autoclave sterilization is required. Additionally, the PS type is available in basis weights of 16 to 106.2 g/m² and thicknesses of 29 to 195 μm, accommodating a variety of applications. *For more details, please refer to the PDF document or feel free to contact us.*

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.*
