![PVC Double Wall Fabric]()
PVC Double Wall FabricPVC drop stitch fabric is a high-strength, air-tight material used primarily in inflatable structures (boats, paddleboards, air floors, and inflatable shelters). Unlike standard PVC tarps, it...view more
PVC Double Wall Fabric
We provide double wall fabrics, which consists two fabric layers interlocked with pile yarns. The pile yarns produce a strong connection between two layers. The height of fabric is between 5mm to 335mm, which are made of industrial polyester yarns.

Features of PVC Double Wall Fabric
Strong adhesion
By means of strict product formulation, increase the molecular penetration of the coating and the base in the process, make the filme and the coating combined. The molecular bond in the middle of the formation of a one-piece, become a unit, after thousands of times of folding, ensuring that the surface layer and the base cloth will not fall off, tear strength can reach 150N/square meter
Flame retardance
GSTARP is manufactured with the highest quality flame retardants, although the highest grades are expensive, which ensure that the product is flame retardant, self-extinguishing when removed from the flame.
Anti-bacterial and anti-mold
Using special chemical additives, we ensure that all our products have good anti-bacterial and anti-mold effects, do not produce mold in humid and warm environments, maintain the stability of the surface, and do not produce unpleasant odors, prolonging the use of the life of the product.
Anti algae
GS PVC vinyle is often used in the field of water-contact areas, especially for water storage containers, aquaculture, fish farming, are required to prevent algae, in the manufacturing of the upper and lower bottom molds, GS has specially added additives to prevent algae, so the tarpaulin is algae-proof.
How To Use
The double wall fabrics are base fabric for coating, such as PVC, TPU and Rubber, the coating fabric can be used to filling with air, gases, gel, liquids, etc.
Product Characteristics
Double wall fabric with drop stitches in the middle, supply 3D stability region
Drop stitches give supports to every spot of the surface, avoiding depressed deformation.
Favorable adhesion during the welding process
Rock-hard rigidity, recommended pressure 20-30 PSI.
