About Neoprene
About Neoprene. Polychloroprene (a.k.a. Neoprene, Chloroprene Rubber) is the first synthetic rubber produced commercially by the free radical emulsion polymerization of chloroprene. It was first marketed by Dupont in 1933 under the DuPrene brand, and after significant improvements in the production process the brand was changed to Neoprene. Nowadays, it is one of the most important special rubbers produced, alongside butyl rubber, nitrile rubber (NBR), and ethylene propylene diene rubber (EPDM).
Chloroprene rubber is produced industrially exclusively via the radical polymerization of chloroprene in aqueous emulsion. The reaction is exothermic and the chloroprene is highly reactive, which favors the production of the homopolymer. However, a chain-transfer agent is often required to prevent the formation of highly cross-linked product, with high molar mass, which cannot be processed, even at low conversion rates. Such agents, like n-dodecyl or xanthogen disulfides are added, and the chloroprene conversion rates are usually limited to a maximum of 70%.
Several polymer properties can be obtained through the proper control of polymerization conditions such as the nature and quantity of chain-transfer agent, the degree of conversion, reaction temperature and the presence of any co-monomers.
Neoprene Handling. Chloroprene, similarly to other chlorinated paraffins, is non-corrosive at ambient temperatures, so it can be stored for many months without deterioration, if away from sunlight. It is usually transported and stored in drums (internally lacquered) or mild steel containers (internally lined with epoxy or phenol formaldehyde resins).
Neoprene Production. Raw materials and the respective production processes employed in the manufacturing of Neoprene are listed below.
- Acetylene + hydrochloric acid (radical polymerization of chloroprene),
- Butadiene + chlorine (radical polymerization of chloroprene)
Neoprene Uses. The uses and applications of Polychloroprene may vary according to its specification. The main forms of Polychloroprene are general-purpose grade; crystallization resistant grade; adhesive grade; specialty grade; and latex grade.
