Waterproof sheet
Waterproof sheet is a kind of excellent impervious material made of high polymer basically. This kind of sheet has many excellent physical and mechanical properties, such as pull-resistance, rip-resistance, bursting and so on, so it is fit for almost all kinds of working condition and can meet the demand of water conservancy, chemical industry, tunnel, transportation and other construction. Waterproof sheet is no toxicity, aging resistance, corrosion resistance, acid and alkali resistance, good endurance, high coefficient of friction, high puncture resistance strength and can be used for different temperature range of condition. It is easy to construct with a great effect., and there is no problem to use it over 50 years under the -50C～100C condition.
