waterproof membrane made by SDM Strength Films
SDM strength film is a new generation of strength film researched and developed by Upass Material Technology (Shanghai) co., Ltd in 2012 independently.
SDM strength film is kind of High Density Polyethylene (HDPE) Cross Laminated Strength Film.
We take HDPE as raw material, and blow to be a cylindrical film with certain thickness by film blowing machine. Secondly, mechanical tensile orientation to finalize the design. Thirdly, the spiral cutting machine cut into sheet film by 45°angle with the original machine direction. Then, coat special glue on the surface of film. The last, cross laminate double-layer in 90°orientation by high-pressure.
The SDM means Spiral cut and Double-laminated Machinery drawing.
SDM Strength film offer you excellent tensile strength, tear strength, puncture resistance and weather resistance.
