Structure Friction materials for industrial machinery are used in various fields, leading to a wide range of performance requirements based on their application. Our company offers a diverse selection of products tailored to meet these various requirements. The material composition consists of inorganic fibers, organic fibers, heat-resistant synthetic resins, and friction performance enhancers adjusted to meet the required performance, all of which are heated and pressure-molded into resin-molded friction materials. [Features] We offer products tailored for various applications such as braking, holding, and conducting. They exhibit excellent mechanical strength, wear resistance, and fade resistance. Even after repeated thermal cycles, there is minimal reduction in the coefficient of friction, providing stable frictional force and outstanding durability.

• clutch

Composition This is a central component of a brake system that uses a drum brake, which is one of the braking methods for the front or rear wheels of automobiles and motorcycles. It generates frictional force by pressing a friction material part called lining against the inside of a rotating body (the sliding part attached to a wheel or wheel called a drum), thereby stopping the rotating body. [Features] The lining is made by mixing a dozen or so types of inorganic and organic raw materials with various shapes, minimizing the impact of factors such as temperature (lining temperature: approximately room temperature to 250°C), humidity, speed, or control input on frictional force, while providing stable frictional force. Additionally, various characteristics can be specialized in the lining to improve these factors, allowing you to choose a lining specification that meets your requirements from the lineup. Furthermore, we consider the environment by improving the friction of the lining, eliminating noise, and complying with laws regarding environmentally harmful substances contained in raw materials.

Structure This is a thermal expansion millboard made by adding a small amount of organic binder to special heat-resistant fibers, special graphite, and heat-resistant fillers, and then forming it using a wet machine (papermaking machine). 【Features】 When heated above 180°C, expansion begins in the thickness direction, and the volume expands to about 10 times. The millboard has thermal insulation and sound absorption properties even before expansion, but its performance improves further after expansion.

• Heating device

Structure It is a flexible material formed into sheet form by an extruder, consisting of a mixture of special heat-resistant fibers, heat-resistant binders, special graphite, and fillers. [Features] EXP sheet is an expandable filler developed to ensure higher safety in buildings. It begins to expand when heated to over 170°C, filling the gaps in joints and preventing the passage of fire and smoke. Additionally, after expansion, it forms an insulation layer that prevents the spread of fire. It is easy to install and a highly convenient product. It is an environmentally friendly product that complies with the "VOC emission rate standards from building materials." Furthermore, EXP2000 does not contain halogens.

Structure Millboard is a heat-resistant board primarily made from heat-resistant inorganic fibers, formed using heat-resistant fillers and organic binders. Disc rolls are created by punching this material into a donut shape (Disc), inserting and stacking it onto a shaft, and then tightening and polishing it to create a heat-resistant transport roll. 【Features】 Practical durability evaluations in stainless steel thin plate lines at temperatures between 1150°C and 1200°C have demonstrated a lifespan equal to or greater than that of asbestos materials. It maintains a balanced combination of hardness and flexibility, resulting in softness that minimizes damage from cracks while also possessing excellent wear resistance. Due to its low thermal shrinkage rate, it exhibits stable transport functionality without deformation over long periods. The high heat resistance of millboard helps maintain the surface temperature of the roll while reducing cooling energy loss from the shaft, contributing to energy-saving measures.

Structure Using a beater (refiner) employed in the paper industry, a slurry of fibers is created by adding special synthetic rubber latex, which is then formed into a uniform sheet using a wet machine (papermaking machine). 【Features】 It has good smoothness and particularly excellent sealing performance at low surface pressure. The handling of the sheet is good, and it has excellent processability. It possesses self-sealing properties due to moderate oil swelling. It has good stress relaxation characteristics and exhibits minimal torque reduction in the sheet.

Structure This is a semi-metallic gasket sheet coated or adhered with a mixture of special heat-resistant fibers, heat-resistant binders, and fillers on both sides of a metal plate via adhesive. 【Features】 Because it uses a metal reinforcement plate, it is a product that can be used under harsh conditions, such as in internal combustion engine cylinder head gaskets. We offer sheets with different characteristics according to applications and usage areas such as pressure resistance, heat resistance, and sealing fluids. *For more details, please download the PDF or feel free to contact us.

The "Heat Resistant Joint Sheet" is a product developed as an alternative to asbestos products. By using a special heat-resistant binder, its heat resistance is improved. It can withstand sudden changes in temperature and pressure. Additionally, it can be handled in the same way as conventional non-asbestos joint sheets and asbestos products. 【Features】 ■ Maintains high sealing performance even under high pressure ■ Reduces construction time during gasket replacement due to minimal adhesion to flanges ■ Has sufficient compressive strength, allowing for tightening similar to asbestos products *For more details, please download the PDF or feel free to contact us.
