三晃商会 List of Products and Services

General oil-resistant rubber (NBR) does not allow light to pass through due to black carbon, but this material has been made into translucent NBR by eliminating carbon. The reduction in physical properties due to the absence of carbon is minimal, and moldability is not an issue for simple shapes. We also provide test piece samples and can conduct oil immersion tests (additional costs to be discussed). 【Specifications】 ■ Hardness (HS): 50 ■ Tensile strength (MPa): 9.2 ■ Elongation (%): 650 *For more details, please refer to the PDF document or feel free to contact us.
