How to identify the quality of foam rubber insulation materials?

       When we choose rubber-plastic insulation board, we can choose different types of rubber-plastic board according to our different needs. How to choose good quality and cost-effective among many types of rubber-plastic board?

       Observe the appearance quality of rubber-plastic board. First, look at the color of rubber-plastic board. The color is uniform and glossy. It has medium hardness, acid and alkali resistance. It can work in -30-+60℃. It can be used to punch various gaskets with good sealing performance with alkali resistance requirements. Check the paint quality of rubber-plastic board. Put the floor in the light to see if there are bubbles, pitting, orange peel and other phenomena on its surface. Then see if its paint surface is rich, full and flat. Test it on the press to know whether they cut corners.

       The intrinsic quality of rubber-plastic insulation board first looks at the material, which can be used for hand twisting and visual observation. If the floor is light in the hand, the insulating rubber-plastic material indicates that tender bamboo is used. If the texture is unclear, it means that the bamboo is not fresh. Observe whether the structure of the rubber-plastic board is symmetrical and balanced. The cross-sections at both ends of the rubber-plastic board are symmetrical and balanced, and whether there is stratification. Silicone rubber and plastic have outstanding resistance to high and low temperatures, ozone and weather aging.
