EPDM waterproofing roofing membrane
1. Introduction:
1.Product composition
This waterproof coiled material is of high elasticity with best performance among high polumer
waterproof coiled material in the world.It is also the most typical one in the world.Waterproof
coiled material made of ternary ethylene-propylene rubber is produced withthe use of the most advanced contiuous extrusion and vulcanization technology and related
equipments which are specially designed for production of such product.It is good in compactness,
without bubble and performance difference in length and breadth,perfomances reach or exceed the demands of GB18173.1-2000 standard.
2. Advantages of epdm membrane
1>Excellent antiaging performance, service life up to 50 years
2>Working well with in 40C to 100C,it canbe constructed with a single layer in ambient temperature.
3>Waterproofing on various kinds of underground project,industrial of civil buildings and structures.
4>high extension rate, high tensile strength, small size changes at heat treatment
5>Good plant roots penetrability resistance and can be made waterproofing layer of planting roof
6>Special modified molecular structure ,effectively resolving the current domestic and foreign glue joint problem .
7>Good low temperature flexibility, and good performance of adapting to ambient temperature changes.
8>Convenient application ,solid joint, no environment pollution
9>chemical corrosion Resistance, can be used for special occasions
10>Convenient maitenance, low cost.
3. Application Scope of epdm membrane
Widely used in roofs, basement, toilet ,swimming pool, and all kinds of industry and civil building
waterproofing, reservoir, vivicism, bridge, underground, tunnel and dam waterproofing ,especially
to the keystone waterproofing projects which is durability, high corrosion resistance and easy
deformation.
