Pond Liner EPDM Rubber Waterproof Membrane
Roller shutter door , also known as "shutter door", lots of panel pieces connected together, fixed in the guide rail , take above reel as the center of rotation.
Roller shutter door is used for commercial facades, garages, shopping malls, hospitals, factories and mines and other public places or residential.Electric roller shutter door, especially for large openings, inconvenient to install the ground door , quick opening effect. Such as for the garage door, shopping mall fire shutter door.
Opening methods: Handing driving mode

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