Is the polymer waterproofing membrane good? What is the difference with other materials?

May 07,/2022

There are many different kinds of polymer waterproof sheet materials, such as homogeneous sheet, composite sheet, self-adhesive sheet and special-shaped sheet. There are many categories under each category. Today, I will introduce several common polymer waterproof rolling materials.

EPDM waterproofing geomembrane:
EPDM rubber (ethylene, propylene, non-conjugated diolefin copolymer), mixed with the appropriate amount of butyl rubber, softeners, reinforcing agents, fillers, accelerators, vulcanizing agents and fillers, etc., by the dense refining, plastic refining, filtering, sheet pulling, extrusion or calendering molding, vulcanization and other processes made of high strength, high elasticity of waterproofing membrane.
Polyvinyl chloride (PVC) waterproofing membrane:
Polyvinyl chloride (PVC) waterproofing sheet material to implement the GB12952-2011 standard, is the main raw material of polyvinyl chloride resin, mixed with plasticizers, fillers, antioxidants, ultraviolet absorbers and other additives, by mixing, plasticizing, extrusion, calendering, cooling, winding and other processes processed from the coil.

Thermoplastic polyolefin (TPO) waterproofing membrane:
Thermoplastic polyolefin (TPO) waterproofing membrane, the implementation of GB 27789-2011 standard, is based on TPO elastomer, with flame retardant fillers, weathering pigments, antioxidants and light stabilizers, etc., by high-speed mixing, melt extrusion calendering molding made of sheet waterproofing materials. Mechanical fixed pavement applied to the roof waterproofing project. Because it has both the weather resistance of EPDM rubber, but also has a plastic waterproofing membrane weldability, waterproofing effect is reliable, so the rapid development.

HDPE self-adhesive waterproofing sheet material
HDPE self-adhesive waterproofing membrane consists of polymer sheet, self-adhesive membrane, anti-adhesive layer. High-molecular self-adhesive membrane waterproofing roll-roofing and concrete in the cement slurry in the initial set under pressure, through creep, phase penetration through the anti-adhesive layer, forming an effective interpenetrating bond and huge intermolecular force. Concrete curing polymer self-adhesive membrane waterproofing membrane and the gap between the main body of the structure to get the maximum permanent seal, completely eliminate the water channel. Waterproofing roll-roofing material that prevents water run-off on the bonded surface.


Polyethylene polypropylene
Polyethylene polypropylene composite waterproofing membrane is a waterproofing membrane made of polyethylene as the main raw material, adding anti-aging agents, stabilizers, adhesion aids, etc., and high-strength polypropylene (polyester) non-woven fabric, after a plastic process of composite. Three-layer structure, surface enhancement, core layer – the main waterproof layer using linear low density polyethylene (LLDPE), the surface of polypropylene (polyester) non-woven fabric, through the composite with the core layer, solve the shortcomings of polyethylene linear expansion coefficient. It increases the roughness of the product surface, improves the friction coefficient of the product, and enables the bonding problem of the composite membrane to be solved and cement bonding to be realized.
