individual roll with top and bottom label ,and the shrink film,then the carton.
bitumen waterproofing tape/joint tape:
1,cold-application and hot resistance
2,guarantee for 15 years
Our production bitumen flashing tape adopt the German technology, and the most advanced international formulations suitable for the manufacture of light steel structure waterproof anti-corrosion materials, low cost, higher than the life of the steel structure itself 1-2 times, environmental materials to fill gaps in the domestic steel structure waterproofing !
The product is a kind of polymer modified asphalt materials, using polyester carpet or glass mat for the matrix, the surface covered with polyethylene film, aluminum foil or fine sand, the back is covered with a release sheet,keep the self-adhesive modified bitumen flexible and waterproof. The product has a good self-adhesive and bending properties.
Construction and other base face is simple, clean, and can be widely used in roofing, basement, bathroom, etc. waterproofing works, and for legislation to pave and stick and pipe wall (except heat pipes), bridges , and other complex environment, especially in open flame is prohibited, covert fire waterproofing works.
Self-adhesive modified bitumen membrane with a self-adhesive surface of the waterproofing, sealing material, divided into with base membrane and without base membrane.And one side with self-adhesive layer and two sides with layers two kinds.The self-adhesive layer has covered with release sheept. the material of realease sheet also has a few kinds. all the self-adhesive layers no need glue, just because the adhesive of itself, which is acaused by the modified bitumen. Low-temperature-resistant properties of the product, and the MTR, tunnels and the scene of the fire with the best waterproof, moisture resistance and sealing materials, also apply to pipeline waterproof, anti-corrosion works.
The product meets the industry standard JC 840-1999 “self-adhesive plastic bitumen waterproofing membrane”. The requirements to main physical properties are listed in table 2.
