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.

The "VN type" is an extremely distinctive wet non-woven fabric made of 100% strongly bonded vinylon fibers. In addition to high strength, it exhibits numerous excellent properties such as fold resistance, abrasion resistance, chemical resistance, oil resistance, corrosion resistance, and heat resistance. It is suitable for applications such as battery separators, civil engineering materials, plywood reinforcement materials, and acoustic components. 【Features】 ■ High strength ■ Fold resistance ■ Heat resistance ■ Chemical resistance (alkaline) ■ Abrasion resistance *For more details, please refer to the PDF document or feel free to contact us.

The "TH type" is a wet non-woven fabric made of 100% polyester, featuring characteristics such as dimensional stability and resin impregnation. It comes in high-density 05TH, low-density 15TH, and ultra-high-density S, with thermal dimensional stability stable up to 200°C. Additionally, due to its high smoothness and resin adhesion, it can be used not only for industrial applications but also across a wide range of other fields. 【Features】 ■ Printability and insulation ■ Dimensional stability ■ Chemical resistance ■ Weather resistance ■ Smoothness *For more details, please refer to the PDF document or feel free to contact us.

The "HOP type" is a wet non-woven fabric made of 100% polyolefin, which is finer and consists of single fibers compared to dry types. The polyolefin fibers are core-sheath fibers of PP/PE, where the PE sheath melts on the dryer surface, firmly bonding the fibers together without the use of any adhesives. Additionally, the sealing temperature is around 140°C. Since no chemicals are used and bonding can be achieved through heat, it can be safely used for food and medical applications. 【Features】 ■ Heat sealability (both sides can be heat sealed at approximately 140°C) ■ Thermoforming ■ Hydrophobic ■ Electrical insulation ■ Oil absorption ■ 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.*

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.*
