Self-adhesive foam water seal can be made of neoprene foam or prepared into PVC foam with similar properties.Dongsheng seal tells you that the main requirements are high density of micropores, good recovery after compression and small sealing force.Water seals can be made into different densities, generally low or medium density suitable for tricky shapes or contours;High density low compression rate foam has load-bearing performance for heavy duty occasions.In the case, the foam seal material can be replaced by high viscous rubber resin.Some examples of self-adhesive PVC foam compressed water seals can be referred to Table 1.
