Ultra-low-hardness rubber offers stable sealing performance due to the inherent softness, flexibility and conformability.
KARU-SPO appears to be a perfect replacement material for many applications where softness and resilience are required.
Sealing material, waterstop, shock absorber
Hardness = Zero (0) by durometer type E
Ultra-soft and ultra-lightweight for easy integration.
KARU-SPO features low compression set that is critical for long term sealing performance.
EPDM with excellent ozone resistance.
EPDM have wheather resistance even at outdoor environments.
Continuous vulcanizing by extrusion process
Longer lengths are possible to be manufactured.
Its bring good cost performance due to low specific gravity.
The testing are performed in accordance with the methods specified in JIS K 6251, JIS K 6259-1, JIS K 6262 standard.
Ozone resistance: 50pphm, 40℃×96hrs, 20% extension
