PVC

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.
