The misunderstanding of many people is that the raw rubber can not be folded, and the cooked rubber can be folded. In fact, this is wrong, because the hem is to remove the intermediate plastic, so the hem mainly depends on the thickness of the aluminum skin. Under normal circumstances, more than 8 wire sold in the market is fully satisfied with the need for 90 degree right angle folding. If the roller arc is required, the angle of the rounding is selected according to different construction requirements. The intermediate core material of the aluminum-plastic composite board is divided into raw rubber and cooked rubber. If the roller is circular, the raw rubber can only be used with raw rubber.
