Waterproof Membrane Formula

The main component of the waterproof membrane is polyvinyl chloride resin, which is added in the extrusion process: plasticizer, stabilizer, titanium dioxide, modifier, etc. to form the current PVC membrane.

PVC Resin

The PVC resin used for waterproofing membrane processing is the suspension method. Depending on the raw materials used, there are two types of resins on the market.

Calcium carbide method PVC resin: The raw material is converted from coal, and there are relatively many impurities. The quality of the resin is not as good as the ethylene method, and the cost is low. Ethylene PVC resin: high purity, expensive raw materials, and high cost.

Impurities in the PVC resin may accelerate the degradation of the coil. For exposed coils with high requirements, the ethylene method is used to synthesize PVC resin.

Plasticizer

Commonly used plasticizers are DOP and DINP. Of course, there is also DOA as a low temperature-resistant auxiliary plasticizer.

DINP with the best molecular weight among the three plasticizers has the highest flash point and is the least volatile.

In practical applications, among the above three plasticizers, DINP and PVC are the least likely to migrate and volatilize from the resin after mixing and plasticizing, that is, exuding from the coil.

Stabilizer

PVC is easily degraded after heating. As long as the temperature exceeds 80 degrees Celsius, after a long time of heating, it will first decompose HCl to form a double bond.

As the decomposition accelerates, the double bonds gradually increase, and the PVC will become more and more yellow. After reaching a certain level, the PVC chain will break and the color will change from yellow to black, completely decomposing.

The function of the stabilizer is to prevent the degradation of PVC during thermal processing. Commonly used stabilizers for commercial coils are lead salts, which have good long-term thermal stability and a certain degree of self-lubricity. The only disadvantage is that lead, like heavy metal, is harmful to the human body.

Advantages Of PVC Waterproof Membrane

● Good fireproof performance: The waterproof membrane does not support burning, and has safety performances such as self-extinguishing away from the fire.
● Quick installation: the construction process is simple.
● Convenient detail processing: It is more suitable for roofing systems with many nodes and complex structures.
● Convenient maintenance and repair: reliable welding basically does not require post-maintenance, and welding repair almost does not cost.
● Good dimensional stability: fits various shapes, and the finished construction effect is beautiful and neat.
