Rubber products forming, after high pressure, because of the cohesion of the elastomer can not be eliminated, in the molding of the mold, often produce extremely unstable shrinkage

1. Rubber products forming, after high pressure, because of the cohesion of the elastomer can not be eliminated, in the molding of the mold, often produce extremely unstable shrinkage (rubber shrinkage rate, due to different rubber and differences), must be after a period of time, in order to slow and stable. Therefore, when a rubber product design at the beginning, regardless of formula or mold, need to be carefully calculated with, if not, it is easy to produce product size instability, resulting in low product quality.

2. Rubber is a heat-soluble thermosetting elastomer, while plastic is heat-soluble and cold-setting. Rubber due to sulfide types of the main body is different, its molding curing temperature range, there is a considerable gap, and even because of climate change, indoor temperature and humidity. Therefore, the production conditions of rubber manufactured products need to be adjusted moderately at any time, if not, it may produce differences in product quality.

3. Rubber and plastic nine-longitudinal bubble structure can effectively prevent heat conduction

4. Thermal conductivity, not more than 0.034W/m· K at 0°C.

5. High surface heat release coefficient, up to 9W/ MK

6. With excellent water vapor resistance, moisture resistance μ≥5,000 constitutes the "built-in" water vapor proof layer, so that the insulation board is both an insulation layer and a moisture-proof layer.
