EPDM Rubber Rolls

EPDM is a highly flexible, high temperature insulation material which is applicable in the fields of sanitary, solar and heating. It is black in colour and best suited for solar thermal and hot water insulation applications. EPDM is available in sheet and tube form. The standard thickness of sheets and tubes are 9mm, 13mm, 19mm, 25mm, 32mm, 38mm and 50mm. The sheets are 1 meter in width and the length of the tubes is 1.83 meter (6 Ft.) per piece. The tubes are available from an internal diameter of 6mm (1/4 inches) to 140mm (5-1/2 inches).

Benefits :

  • All weather resistant
  • UV Resistant
  • Ideal for vrv and solar application
  • Eco friendly
  • Temp range from – 200C to 150C
  • Quick and easy to install
  • Does not corrode copper tubing
  • Free from cracking
  • Longer life.

Applications :
Duct insulation, Chilled water piping, Roof insulation, Terminal insulation, Cold Storage applications, Clean room applications, Solar Plumbing, Raised floor insulation, Refrigerant piping.
