Description

The material is made up of polyester/ glass fabric mat as frame, styrene-bivinyl-styrene (SBS) as modifier and polyethylene film / aluminum film / sand grain / colored sand / sliver as surface coat. There are several advanced colloid grind and thermal conduction oil stove of 1 million-calories power in our factory, which guarantee the quality of our products. Polyester, such as SBS, can be dispersed in the pitch, forming a reticular structure. As a result, the performance of products has been improved, such as high four-way pulling force, good elongation percentage, strong ductility, low temperature proof, aging proof, ultraviolet radiation proof&#****2;temperature difference proof, self cured bonding and so on. Especially, period of validity can reach *5 years because of the quality guide line which is very strict in our factory.
