Neoprene Diaphragm Rubber Sheet

Reglin Neoprene Diaphragm is a premium grade weather and heat resistant rubber sheet with nylon reinforcement.


Reglin Neoprene Diaphragm Rubber Sheet is made from a premium Neoprene rubber compound and will display high temperature resistance.

Neoprene Diaphragm is reinforced with a specifically designed nylon fabric to give a high burst strength and a good flex life. This fabric also gives improved tear strength and dimensional stability.

Neoprene Diaphragm has excellent physical properties including mechanical strength and abrasion resistance.  It has excellent ozone/UV resistance making it weather resistant and suitable for prolonged outdoor use.

Neoprene Diaphragm exhibits moderate resistance to oil and petroleum-based products including a range of fuels, greases, solvents and hydraulic fluids. It will also display some chemical resistance to acids and alkalis.


Reglin Neoprene Diaphragm Rubber Sheet has been designed primarily for use as a flexible rubber sealing diaphragm.

It is typically used for sealing in a range of flow control equipment.

Neoprene Diaphragm is suitable for use in applications with high operating temperatures and exposure to slurries, water and air and is suitable for use outdoors with UV exposure.

Its properties make it suitable for use as a diaphragm in a range of equipment including:

  • Pumps
  • Valves
  • Solenoids
  • Actuators
  • Regulators
  • Dust collectors

Neoprene Diaphragm can also be used for any application which requires a tear resistant flexible Neoprene rubber such as transfer sleeves and expansion joints.
