What is the difference between PET waterproofing membrane and BAC waterproofing membrane? What is the commonality? Is BAC a PET?
BAC is not equal to PET, carcass material is not the same, and BAC also fiberglass tire coil.
BAC refers to butyl acetate, BAC waterproofing membrane is a composite double-sided self-adhesive rubber asphalt waterproofing membrane, the coil material in the polymer (chain) and cement hydrate (silicate network) (Interfacial) interpenetrating network (IPN) structure, cement can be flow, infiltration or impregnation, solidification strength increases, the cohesive force increased. The leakage caused by the damage caused by the coil can be limited to the local scope, to avoid leading to the overall failure of the waterproof layer. BAC composite self-adhesive waterproofing membrane elongation performance, with a unique self-healing function, can self-healing smaller puncture damage, can automatically fill the smaller grass-roots cracks.
PET refers to polyethylene terephthalate, PET film using polyester composite film as the surface material, coated with rubber asphalt adhesive material, with cement mortar paste or self-adhesive. Can be constructed on the wet base surface, the grass-roots requirements are low, with high bond strength, bonding effect is good, not channeling water and so on.
