Water Tank Material


Ok tarp tent materials are produced by advanced coating and stress release technology, and raw materials are formulized by the high degree of polymerization PVC resin. Ok tarp supplies consistent quality and ensures all parameters are within technical specifications like thickness, weight as well as mechanical parameters.

With advanced coating plus tension release technology, product flatness and elongation after installation are much better ensured which helps customers reduce the maintenance cost and ensured product performance.

Ok tarp advanced surface lacquer technology plus the Europe lacquer materials ensured the lacquer quality and self-clean performance.



1, Excellent tensile, tearing, and adhesion resistance.
2, Fire resistance, anti-UV,anti-mildew, oil proof and stain resistance, acid and alkali resistance.
3, High and cold temperature resistance, anti-oxidation, weather resistance, and durability.
4, Self-cleaning function and long service life.



Variety of patterns and colors
In addition to the classic blue, various prints are also available.

Anti-wicking treated yarns are available to minimize the risk of leakage.
