We have developed a "high specific gravity rubber (NBR)" with a specific gravity of 3.5 (or 3.2). To increase the specific gravity, we do not use solid materials such as metal powders, which helps prevent damage to production equipment. It is free from lead and iron, and complies with the RoHS2 directive (10 substances) and REACH regulations. It can be processed and molded just like general-purpose NBR (specific gravity 1.0 to 1.2). 【Examples of Applications】 ◎ Vibration-damping materials ◎ Soundproofing materials ◎ High-load cushioning materials ◎ Measures against rattling noises in electrical appliances and automotive parts ◎ Deadening materials for acoustic equipment, etc. *For more details, please refer to the PDF document or feel free to contact us.

Expansion joints (rubber joints) are used for preventing vibrations and noise generated from piping systems, absorbing expansion and displacement due to temperature and pressure changes, as well as accommodating various dimensional fluctuations during installation and mitigating or preventing the effects of earthquakes and ground subsidence. They are considered essential components in piping installations. The E-P joint was launched in 1970 (Showa 45) as a low-pressure R type for elevated water tanks. Since then, it has expanded to include new products that meet customer needs, such as the high-pressure P type integrated with PTFE and the F type. Today, it is used by a wide range of customers across various industries, from household drinking water to chemical plant piping. 【Features】 1. Pressure type PTFE (polytetrafluoroethylene) inner surface coating type 2. The liquid-contacting part (inner surface) uses PTFE, which has excellent chemical resistance 3. Improved resistance to external impacts through integration with durable and strong rubber For more details, please contact us or refer to the catalog.
