The 100% cured EPDM membrane is made of a synthetic rubber Ethylene-Propylene-Diene Monomer. The membrane is weldable with hot air and extremely durable, and has excellent thermal shock and UV rays/ozone resistance. It retains its elasticity at temperature from -45ºC to 130ºC and resistant to temperature shocks up to 250ºC,  quick and easy to install. Features
- Excellent tensile strength and elongation rate, dimensions stability, long service life
- Good welding characteristics and resistant to UV/oxidation/heat and ozone
- Superior mechanical properties and stability and flexibility at low and high temperature Â
- High puncture and tear and impact resistance
- Excellent gas impermeability and resistance to acid rains, low weight
- Quick and easy installation, no need of flames or torches Uses
* Roofs or re-roofing, underground structures of residential and commercial buildings
* Parking lots, reservoirs, swimming pools, sewage treatment plants, warehouses
* Highway, airports, railway, bridges, tunnels
* Especially for the projects with high requirements in durability, anti-corrosion, and deformation
