Made in Japan
Manufacturer: Naigai Rubber Industry Co.,Ltd
Product name: Hanenite Anti-vibration Rubber

HANENITE vibration suppression rubber has excellent performances of absorbing shocks and vibrations. Even when an external force is applied, the rubber absorbs the energy with almost no repulsion. Moreover, the material boasts excellent physical properties and durability, on par with those of normal rubber. As a result, this rubber does not bounce when it falls, defying the conventional expectations of rubber’s behavior.

・Excellent vibration damping performance at room temperature (5 to 35℃)!

The repulsion elasticity is less than 10%, excluding CP-S, indicating a significantly reduced bounce-back effect in comparison to other materials.

・A lineup with +α characteristics!

Excluding CP, the capability to cut and punch sheet materials remains achievable, thus enhancing its versatility in practical applications.

CP-S: Can be used up to -20℃.

・Free shapes created by excellent workability!

This material can be molded using the same methods applied to general rubber, demonstrating its flexible manufacturing potential.

Strong adhesion to metal is possible.

Apart from CP, the ability to cut and punch sheet materials is indeed possible, thereby broadening its range of practical uses.

The sponge sheet is notably lightweight!

Closed cell vibration damping sponge with a specific gravity of 0.3.

・Environmental measures initiatives

Rohs Directive: Compatible with all grades

REACH regulations: Compliant except for flame retardant grades (GP-40HBE, GP-50V)

Examples of commonly used locations

・For impregnation of motor coils for air conditioners and refrigerators

・For coil impregnation of other sealed motors, etc.
