Chloroprene Rubber
Chloroprene Rubber – (CAS 9010-98-4) Supplier in South Africa
Overview of Chloroprene Rubber
Chloroprene Rubber, commonly known as CR or Neoprene, is a synthetic rubber produced from polymerization of chloroprene (2-chloro-1,3-butadiene). It is highly valued for its excellent chemical stability, weather resistance, and flexibility, making it suitable for a wide range of industrial and commercial applications.
Chloroprene Rubber is widely used in automotive, construction, marine, and manufacturing industries due to its durability and resistance to oils, solvents, heat, and ozone.
As a trusted supplier in South Africa, Forge Chemicals Limited provides high-quality Chloroprene Rubber suitable for various industrial and manufacturing applications.
