the surface layer turns round take the polyethylene membrane (aluminum foil either colored sand ) as the superficial material , the bottom surface uses the silicone oil anti-seize to isolate the paper the volume material
or both siders for the silicone , oil islates the waterproof volume materials which paper two-side may cake is a
waterproof layer

high polymer metal aluminum foil waterproof volume material
* extends higjh ,phenomenon which effectively the high elasticity , high tensile strength
* good anti-aging
* construction to facilitate to avoid joining which place the volume material existence big stress trend created easy
breaking effectively the phenomenon to have and the basic unit cementation high performance
* avoid fleeing water phenomenon's occurrence to avoid adhesive not water resistant glued joint surface degum ,is unable to restore
