Shock-absorbing and vibration-damping rubber with excellent performance! Outstanding vibration-damping capabilities in the normal temperature range (5-35°C)! Numerous achievements as an anti-vibration material! *Compliant with RoHS2 directive.

The vibration-damping rubber, which excels in shock absorption and vibration absorption, absorbs energy without much rebound even when subjected to external forces. Hanenite GP35LE is the most common grade among Hanenite products. It demonstrates the best vibration-damping properties in the room temperature range. Additionally, it has excellent oil resistance, making it safe to use around various machinery and oil environments. Its physical properties and durability are comparable to those of general rubber. It is widely used as cushioning material and vibration-damping components for quiet and low-vibration products. 【Characteristics】 ● The rebound elasticity is 2% (measured value). ● Load capacity is approximately 800 kg (for 10×100×100 mm with 10% deflection). The values may vary depending on the pressure area, so please contact us for details. ● It can be processed into various shapes. Molding similar to general rubber is possible. Cutting, machining, and punching of sheet materials are also acceptable. ● Strong adhesion with metals is possible. ● Teflon coating (vulcanized adhesion) is possible for surface adhesion prevention and wear resistance improvement. *For more details, please refer to the PDF materials or feel free to contact us.

Pressure type! Absorbs vibrations, noise, expansion, and displacement in piping systems! Active in vibration isolation for general-purpose pumps and blowers in factory equipment, as well as absorbing expansion in heat-resistant resin piping!

Expansion joints (rubber joints) are used to prevent vibrations and noise generated from piping systems, absorb expansion and displacement due to temperature and pressure changes, and mitigate or prevent the effects of various dimensional changes during installation, as well as impacts from 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 added new products to meet customer needs, including the high-pressure P-type integrated product F-type with PTFE. Today, it is used by a wide range of customers across various industries, from household drinking water to chemical plant piping. 【Features】 1. Stable durability due to the combination of strong reinforcing fibers and reinforcing steel wires. 2. EPDM is used for the inner and outer rubber, providing excellent chemical resistance and weather resistance. 3. The use of loose flanges facilitates installation work.
