Preparation of Neoprene

May 3 • General • 7752 Views • 7 Comments on Preparation of Neoprene


Neoprene comes under the family of synthetic rubber which is primarily produced from petroleum by-products

 Some Properties:-

  • Good chemical stability
  • Flexibility over a wide range of temperature


  • Neoprene is referred as rubber but basically it is plastic.
  • A powder called polychloroprene is first of all introduced
  • Ingredients that provide elasticity, color, foaming agents are added as base
  • The complete mixture is made to dough and then allowed to heat.
  • Under exact pressure and heat the mixture comes out be a sheet of about 90”× 53”
  • The sheet size varies according to the neoprene used.

The figure below shows the immersion suit construction:

Neoprene is an important ingredient of immersion suits for waster rescue teams

There are two types involved while constructing immersion suit using


-> Blind stitched is water-proof and remains invisible from the outside when stitched from inside.

-> In flat lock an exterior fabric tape is used.

Most of the properties of this polymer is similar to that of natural rubber but it is more resistant to the actions of oils and to other hydrocarbons as compared to natural rubber. It is inflammable and also is resistant to heat, oxygen and sunlight.
