Traditionally, the shape of the outer solid sponge has been considered difficult to form integrally through extrusion due to issues such as the escape of foaming gas from the solid. Our company's "Functional Rubber Series Coated Sponge" resolves these issues through our formulation and nozzle expertise. We have successfully achieved integral molding through two-layer continuous vulcanization extrusion, improving production capacity. It is optimal for areas requiring the softness of sponge and the strength of solid. 【Features】 ■ Supports long lengths → Length can be freely chosen due to continuous molding! ■ Good distortion → Compression permanent distortion of 16% during processing! ■ Flame retardant → Passes railway vehicle material fire tests! ■ Productivity → Excellent productivity due to two-layer continuous vulcanization extrusion!

• Rubber

Rubber extrusion molding (continuous vulcanization) is considered very difficult for molding materials with low hardness because it shapes and induces crosslinking reactions in a non-pressurized state, unlike compression molding and other methods. Our "Functional Rubber Series - Low Hardness" achieves a low hardness of 15° using EPDM solid while maintaining the processing conditions during extrusion molding. It can be utilized in applications where low hardness is required but sponge rubber is too weak. 【Features】 ■ Long Length Support → Since it is continuous molding, the length can be freely chosen! ■ Low Hardness → Achieves 15 degrees on the A hardness scale! ■ Weather Resistance → Excellent weather resistance due to EPDM! ■ Strength → Solid structure provides strength!

This is the Right River Rubber Manufacturing Company, which has been in the rubber manufacturing business for 100 years. We provide services that meet all customer requests, not only for general mass production but also for rubber formulation design, functional material development, nozzle design, and prototype support. 【Examples】 - The shape of the rubber is fixed, so I want you to create rubber that fits the intended use. - I only have a vague image, but I would like to consult with you. - Can this kind of material really be made of rubber? - I don't have a drawing, just the actual item. Is it possible to make the same thing? - Can you create prototypes even for small lots, starting from just one piece? - Although the start was delayed, the delivery date is still next week. Is there any way you can accommodate this? - I am a novice when it comes to rubber. Could you accompany me to explain to the customer? ■ Please feel free to contact us with any inquiries.

• Rubber

By designing the rubber composition, it is possible to manufacture rubber that controls the electrical resistance value (resistance control based on ionic conduction/electronic conduction).

• Anti-static products

The super set form is a highly resilient rubber sponge that brings permanent deformation to nearly zero. It returns instantly, with extremely small permanent deformation and excellent shape retention. It is ideal for packing materials in areas requiring high airtightness and for gasket materials in areas where long-term gas sealing is necessary.

• Rubber

We create various shapes of 2D cross-sections ranging from small items with a diameter of about 2mm to large items of about 150mm! We provide reliable technology for rubber parts centered around extrusion molding across various industrial fields such as automotive, office automation components, construction, civil engineering, and general industrial products. We always strive to respond broadly and meticulously to the diverse needs of our customers, and we quickly execute even small lots or prototype orders.
