What is the difference between polymer waterproof membrane and bitumen waterproof membrane?
Jan 30, 2023
In contrast, asphalt waterproof membrane has poor temperature resistance, large pollution in the production process, relatively short service life, easy to be dirty during construction, and the color is only black. In summer, it absorbs sunlight and heat, which has a great impact on the indoor temperature of the top floor, which is not conducive to energy saving and environmental protection.
Polymer waterproof membrane relative unit cost is high, but good weather resistance, long service life, convenient construction, easy to make light/white products, paving on the roof can effectively reflect the sun, so as to avoid the top floor indoor excessive temperature, conducive to energy saving.
What is the polymer self-adhesive waterproof membrane?
Polymer self-adhesive waterproof membrane is made of rubber or plastic sheet or film as the base material, rubber or thermoplastic elastomer as the self-adhesive layer, by calendering composite of high performance and high creep waterproof membrane. The main self - adhesive layer is butyl rubber and SIS hot melt adhesive.
What is bitumen self-adhesive waterproof membrane?
Bitumen self-adhesive waterproof membrane is made of rubber or plastic sheet or film as the base material, SBS or other rubber modified asphalt as the self-adhesive layer, after coating self-adhesive waterproof membrane. The base material is polymer material, but asphalt self-adhesive layer does not belong to polymer material.
From the above analysis, we can see that the real polymer self-adhesive waterproof coil should be the base material and the self-adhesive layer are both polymer materials, if the self-adhesive layer is asphalt material, it does not belong to the category of polymer self-adhesive waterproof membrane, only asphalt self-adhesive waterproof membrane. Polymer waterproof membrane price is higher than asphalt waterproof membrane, how to choose according to the specific situation.
