💡 What makes epdm rubber ideal for steam and hot water sealing compared to nitrile or viton?
EPDM stays handy under intense heat and moisture while keeping joints sealed tighter than most synthetic rubbers.
- Ethylene propylene diene monomer builds tightly cross linked networks that shut out steam leakage fast
- Molecular structure blocks oxidative wear from ozone and direct sunlight better than cheaper alternatives
- Thermal cycling tolerance keeps gasket tension stable through repeated heating and cooling phases
- Base chemistry chokes off polar liquids and brake fluids while melting near pure petroleum distillates
