Multifunctional Tarpaulin for Military Application

1.Flame Retardant; 2. waterproof; 3. Breathable;4.Infrared resistant; 5. Acid Resistant; 6. Oil-proof

·The main traits of the new tarpaulin of airplane (in army)     a) The base fabric is made of polyester canvas, it just be dyed and  managed to waterproof, no coated, no dipped with mucus. The tarpaulin well in water-vapour penetrative, just like the base fabric.     b) Well in waterproof, the hydrostatic pressure can meet 470mm water column.     c) High in rupture strength and tear strength, meet the standards.   d) Widely used as tarpaulin in airplane、 tank、 folk-car、 provide disaster relief and material’s cover. ·The main traits of the new tank tarpaulin     a) A great improvement in flame retardant, the smoldering time almost reduced to 0, and it can cut down the second fire in smoldering greatly.     b) The coating film with no protrusion, avoiding the damage from the needle and hard, can improve the lifetime of the tarpaulin     c) The new tarpaulin have the function of vitriol resistant, and it can meet the standards of GB12012-89《The acid work clothing and the test method of it’s capability》     d) A great improvement in oil-proof, it can meet the 7th grade (130 marks), the standard is 4th grade (80 marks) actually.     e) The rupture strength and tear strength are better than standards.
