What is Neoprene?

Neoprene or polychloroprene is part of a family of synthetic rubbers that are produced by polymerization of chloroprene. Polychloroprene polymer is the main component of Neoprene and characterised by its heat and chemical resistance, as well as temperature performance.

Alanto supplies closed cell neoprene sponge in a variety of forms:

  • Ref DK1720 Density 140-190 kg/m3, 40-50 Shore Hardness
  • Ref DK1410 Density 115-155 kg/m3, 40-45 Shore Hardness
  • Ref DK1735 Density 150-200 kg/m3, 50-60 Shore Hardness

Strengths of neoprene

This commonly used, synthetic material is:

  • Heat resistant – Alanto’s range of neoprene closed cell sponge materials all have flame retardant specifications conforming to FMVSS302 classification.
  • Chemical resistance - neoprene is a popular choice due to its ability to be undeterred by acids, oils, solvents and other chemicals.
  • High flame resistance – Alanto also supply a neoprene closed cell sponge (DK1620FR) that has enhanced flame retardant qualities which conform to UL94 HF1 classification.
  • An excellent sealant – neoprene requires minimal compression to provide a seal to prevent the admission of water, moisture, dust and air.

What uses does neoprene have?

Many of Alanto’s customers use neoprene closed cell sponge in a variety of different applications due to its excellent temperature, weather and compression resistance, amongst other properties. Typical industries served include:

  • Construction
    • Neoprene is an ideal material for washers, elevator astragals, deviator pads and more.
  • Glass and Glazing
    • Neoprene can be supplied with a self-adhesive backing for use in the sealing of glass and glazing.
  • Shipbuilding and Railways
    • The material is excellent in shipbuilding applications where constant exposure to sea water, rain, UV rays, and temperature extremes are present.
    • Bridge bearing pads and stay-cable anchor components are also commonly manufactured from neoprene.
  • Aircraft and Aerospace
    • There are many applications of neoprene in the aircraft and aerospace industries including environmental sealing, noise isolation, electrical insulation, flame resistance and more.
  • Electrical
    • Neoprene is often used as an insulator in electrical applications due to is fire and static resistance.
  • Engineering
  • Automotive
    • Commonly used for door seals, hose covers, power transmission belts, shock absorber seals, and more.

Other applications of neoprene across the world

Neoprene is a commonly used material that has many uses throughout a variety of sectors...

Industrial applications
Neoprene gloves are an excellent solution to human contact with potentially toxic substances such as hydrocarbon solvents. The material acts as a protective barrier and allows for efficient and safe handling of substances in many industrial environments.

Marine applications
A number of forms of neoprene are popular choices for wetsuits and scuba diving gloves – in these cases, neoprene retains body heat and has high elasticity.

Fire prevention
Neoprene is often the material of choice for fire protection and is used for fire protection accessories such as fire extinguisher cabinets, fire extinguishing hoses and protective gloves.
