Nok Corporation
Nok Biomass O-rings
Manufacturer: Nok.
Features
- It is an environmentally friendly material that uses plant-derived sustainable raw materials for the rubber material.
- Biomass EPDM materials are EPDM materials that have a biomass content of＊1It is an eco-friendly material that has achieved 30%.
* EPDM: Ethylene propylene rubber - CO in polymers2Reduced emissions by 40%.
* CO during raw material manufacturing and transportation2Emissions - When biomass EPDM material is applied to general-purpose O-ring materials for water, they have the same characteristics as conventional EPDM materials.
