Attention on new materials! Paper-based phenolic resin laminate (thick board)
Rishorite paper-based phenolic resin laminate
High strength and insulation! More affordable than glass and carbon fiber FRP. Perfect for material reconsideration!
"Paper-based phenolic resin laminate" is a resin material (FRP) that has been sold for over 80 years at Rishou Industry, maintaining strength and insulation properties while keeping costs low. It can be produced at a lower cost than FRP made from glass fibers or carbon fibers. Additionally, it excels in machinability, allowing for significant cost reductions when used as an alternative material. ■ High resistance to solvents and oils, and strong against bending ■ Excellent machinability ■ Heat resistance up to 130℃ ■ High insulation performance (44,000 volts per 1.0 mm) *For more details, please download the catalog or contact us.

basic information
"Paper-based phenolic resin laminated board" is an FRP that balances low cost and high performance. It is made by layering paper impregnated with a thermosetting resin called "phenolic resin" multiple times, and then applying high pressure while heating it. It is more affordable than FRP reinforced with glass fibers, carbon fibers, or synthetic fibers, and the bending strength of a 3mm thick test specimen measuring 25×60mm exceeds 98 megapascals. Its heat resistance is 130°C, insulation performance is 44,000 volts per 1.0mm, and it is resistant to solvents and oils, with excellent machinability. It can be processed into various shapes, so depending on the application, it can replace expensive materials previously used, achieving cost reduction. *For more details, please download the catalog or contact us.*

Detailed information
-
Processed products are cut into various shapes due to their low cost, despite being made from materials that excel in electrical insulation, heat resistance, chemical resistance, and mechanical strength, and are adopted in many fields.
-
Examples of applications for insulating supports It has excellent electrical insulation properties. Based on the "Through Thickness Breakdown Voltage Test" according to JIS K 6911, it has been found to have a dielectric strength of 44,000 volts per 1.0 mm of material.
-
Examples of mechanical parts used in machinery. In addition to electrical insulation properties, they excel in mechanical strength, heat resistance, and chemical resistance, making them suitable for processing into mechanical parts and fixtures used in areas where metals are disadvantageous, such as thermal insulation, corrosion resistance, rust prevention, and magnetization prevention.
-
Bending Strength Test It has excellent mechanical strength. The bending strength of a test specimen measuring 3mm thick × 25 × 60mm is over 98 megapascals. (The photo shows a 1mm thick specimen.)
-
Excellent machinability PS-1121E has a good balance of rigidity and toughness, resulting in fewer cracks and chips even during fine machining. The photo shows an example of processing for a barber comb (provided by Hirao Comb Manufacturing). It is favored by professionals as a comb that withstands the heat of hair dryers and hair styling products (chemicals).

Phenolic resin laminated pipe made from paper-based material. We also have "laminated pipes" in a tubular form. They are reinforced with paper fibers, making them stronger than pipes made from extrusion or injection molding.
Line up（4）
| Model number | overview |
|---|---|
| PS-1121E | JIS standard: PL-PEM. General-purpose / natural color. A staple of paper-based phenolic resin laminated boards, and a bestseller. |
| PS-1122E | General-purpose / black color. This is the black version of PS-1121E. Some customers specify black because the natural color of PS-1121E deepens over time due to aging. |
| PS-1111E | JIS standard: PL-PEV. First-class product / natural color. This type has a reduced water absorption rate. If electrical performance is required under high humidity conditions, we recommend this type. |
| PS-1152F | Flame retardant: UL94V-0 / natural color |
