Self-adhesive Rubber-asphalted Membrane SAM-920

Brief Introduction:
1. "Yuhong" Self-adhesive Rubber-asphalted Membrane SAM-920 ("Self-adhesive waterproof membrane" for short)
2. Base material: self-adhesive rubberized asphalt combined by SBS elastomeric modified bitumen, viscosity increaser and petroleum asphalt etc.
3. Upper surface material: HDPE film or aluminum foil
4. Lower surface anti-sticking isolating material: removable silicon-coated film or silicon-coated buckle paper

Features of Self-adhesive Rubber-asphalted Membrane:
1. Non-toxic, environmentally friendly
2. Good elasticity and extensibility
3. High adhesive strength
4. Outstanding anti-shear performance
5. Remarked capacity of transferring horizontal load

Applications of Self-adhesive Rubber-asphalted Membrane:
1. Waterproof projects of wood structure and metal construction roofs
2. Waterproof projects that are not suitable for naked flame, such as chemical plants, spinning mills, grain depots etc.
3. Typical Cases: Capital Airport, Beijing-Shanghai Expressway.
