PVC is a ther­mo­pla­stic elast­omer with ver­sa­tile cha­rac­te­ris­tics. PVC pla­s­tics are divided into hard and soft PVC:

Soft PVC con­tains sof­tener that gives the mate­rial elastic pro­per­ties. The added sof­te­ners allow good varia­bi­lity in the hard­ness and dura­bi­lity of PVC.

PVC has many advan­tages:

  • good iso­lator
  • easy to colour
  • low absorp­tion of water
  • resis­tant to aci­dity, alkalis, alcohol, oil and petrol.

Hard PVC can be machined well and can be shaped at tem­pe­ra­tures of 120 – 150°C without machi­ning.

Joins can be made using appro­priate adhe­sives or hot air wel­ding.

Alter­na­tives to PVC are PP (Poly­pro­pylen) or PE (Poly­ethylen), which M+R also supply.
