PVC

PVC is a heavy, stiff, ductile and medium strong amorphous (transparent) material. By adding softeners a range of softer materials can be achieved, ranging from a flexible to an almost rubber-like elastic soft material.

Softeners also help to increase the manufacturability. PVC has brilliant resistance to acids and bases, but is affected by some solvents. Soft PVC is exceptionally resistant to most chemicals.

Tubes made of PVC have the unique ability that they do not kink, i.e. stop the flow if bent. The poor weather resistance can be improved using additives. PVC has good barrier properties to atmospheric gasses.
