Waterproof coiled material
A water-proof coiled material for water-proof engineerings such as railway, highway, culvert and dam contains such components (wt. portions) as ethylene-vinyl acetate resin (30-80), low-density linear polyethylene (10-60) and charge (6-10) and is made up through mixing, extruding, calendering, thermally treating and cutting. Its advantages include low cost, long service life, excellent ageing and low temp resistances, service temp at -35-+120 deg.C, more than 600% of elongation coefficient and tension strength and high anti-leakage nature.
