Neoprene
Before knowing how we make neoprene, we should be aware of what it actually is? It comes under the vast study of science under the chemistry subject and is an important substance that comes in basic uses today. Moreover, it is generally known as Polychloroprene or PC-rubber.
What is Neoprene?
Neoprene is one from the group of rubbers which are formed by the process of polymerization of chloroprene. Moreover, it has good chemical stability and maintains good flexibility over a wide range of temperature.
Furthermore, it is sold in the form of rubber or latex and is also used in a wide variety of applications such as electric insulations or laptop sleeves, etc.
Process of Making Neoprene
The original process of making neoprene consists of the usage of petroleum-based chemicals or oils.
After that, it goes through a polymerization process.
It transforms chemicals into rubber-type chips known as chloroprene. Consequently, we melt these chips and then we add foaming agents and thus it is formed.
Qualities of Neoprene
• Vibration dampening
• Resistance to tearing
• Resistance to weather
• Heat resistant
• Waterproof
• Insulator
• Resistance to many chemicals
• Buoyancy
• Durable
• Flame resistant
• Flexibility
• Stretchable
• Resistance to abrasion
• UV ray resistant
Some Common Examples
1. Gloves
2. Boots
3. Tap Valves
Processing of Neoprene
At the initial stage, neoprene is a powder other ingredients also include. Thus, they help in providing cell size, adhesion, foaming agents, bulk, colour, and many other properties according to the Machovec.
Furthermore, it goes through the heat press and then it turns into a doughy mixture, here the heat and the mixture form a sheet. Moreover, the size of the sheet varies depending upon the type of it and the manufacturer.
The foam block is the last product which measures approximately 2 inches thick from the top and its texture is smooth. Subsequently, these sheets end up as the nylon sheets. Thus, we use them in many styles of waterproof wetsuits or swimsuits.
What is Neoprene Used For?
As it is waterproof so we basically use it in the making of wetsuits. Preventing the water to touch the wearer’s skin or body and keeping the wearer dry inside the water. Furthermore, it also keeps the body warm.
It may vary in thickness depending upon the manufacturer and the type of neoprene. The thicker it is the more it is insulating.
Moreover, they also come in a wide range of colours, styles, and sizes. In industries, they use neoprene in the protection of the cables and the electric wirings.
In addition, they also use it in the conveyor belts and the elevators.
Preparation of Neoprene
• Neoprene is much similar to rubber but basically, it is plastic.
• Polychloroprene is a powder that introduces first.
• Addition of some ingredients happens to provide elasticity base and colour.
• The whole mixture is made into a dough. After that, it is provided heat and later it converts into a sheet.
History of Neoprene
Neoprene was invented by the scientists of DuPont on 17 April 1930 after Dr Elmer K. Bolton attended a lecture of Fr. Julius Arthur Nieuwland.
Further, he was a professor of chemistry at Notre Dame University. After that, DuPont purchased the patent rights from the University Wallace Carothers who was from DuPont.
Furthermore, he took over the commercial development of the Nieuwland’s discovery with the help and involvement of Nieuwland himself.
This was first marketed by the DuPont in 1931 as DuPreme which was its trade name. Therefore, by 1939 its sales generated profits of over $300,000 for the company.
