SS-SNOW barrier grid – raw materials used for production of SS-SNOW ensure its good functioning without deformation or damage at temperature lower than -40 ⁰С. Special type of PVC plastisol (purchased only from European manufacturers) gives the grid elasticity and protection from aggressive atmosphere like UV-light, temperature fluctuation (freezing – defrosting), acid-alkali media. Special light- and heat stabilizers are using for production of the yarns, which are knitted into the grid. Guaranteed service life of polyester grids is not less than 7 years when properly used.
