Waterproofing industry has set off the application of polymer waterproofing materials, which is the fastest growing application of waterproofing membrane, but different waterproofing membrane suitable for different places are not the same, so how do we distinguish between different waterproofing membrane?
1, what is called polymer materials?
Polymer materials, also known as organic polymer materials, also known as polymers or polymers, by one or several molecules or molecular groups (structural units or monomers) to covalent bonds combined into a macromolecule with multiple repeat monomer units, its molecular weight up to 104 ~ 106, it can be both natural products such as fibers, proteins and natural rubber, etc., can also be made by synthetic methods such as synthetic rubber, synthetic resins, synthetic fibers and other non-biological polymers.
Waterproof materials used in polymer materials are mainly rubber, plastic and thermoplastic elastomers, rubber EPDM (EPDM) rubber, butyl (IIR) rubber, neoprene (CR) rubber, natural (NR) rubber, etc., plastic (resin) polyethylene (PE), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA), etc.
2, what is asphalt material?
Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is mainly a by-product (residue) of petrochemical and coal chemical industry. It can be separated into four parts: saturated fraction, aromatic fraction, gum and asphaltene, etc. Asphalt is carcinogenic and can be used as moisture-proof and anti-corrosion materials.
Asphalt waterproofing materials are mainly traditional paper tire linoleum, wax for SBS modified asphalt waterproofing roll-roofing, APP modified asphalt waterproofing roll-roofing, asphalt self-adhesive waterproofing roll-roofing, asphalt waterproofing coatings.
3, what is polymer self-adhesive waterproofing roll-roofing material?
Polymer self-adhesive waterproofing roll-roofing is a sheet or film of rubber or plastic as a substrate, rubber or thermoplastic elastomer as a self-adhesive layer, by calendering composite and high-performance high creep waterproofing roll-roofing; self-adhesive layer mainly butyl rubber and SIS hot melt adhesive, etc..
4, what is the asphalt self-adhesive waterproofing roll-roofing material?
Asphalt self-adhesive waterproofing roll-roofing is a rubber or plastic sheet or film as a substrate, SBS or other rubber-modified asphalt as a self-adhesive layer, coated and made of self-adhesive waterproofing roll-roofing; substrate is a polymer material, but the asphalt self-adhesive layer is not a polymer material.
The real polymer self-adhesive waterproofing roll-roofing material should be the base material and self-adhesive layer are polymer materials, if the self-adhesive layer is asphalt material is not a polymer self-adhesive waterproofing roll-roofing category, only asphalt self-adhesive waterproofing roll-roofing material.
