Chloroprene rubber

Chloroprene rubber (CR), commonly known as neoprene, represents a synthetic class of elastomers with unique insulating properties.


Chemical structure


The chemical structure of neoprene consists of chloroprene, a polymer obtained by polymerization

of chloroprene monomers. The addition of chlorine atoms to the polymer chain gives the rubber

increased resistance to alternating temperatures and chemical influences

compared to natural rubber.


Material properties and resistance


  • is characterized by its electrical insulation properties as well as gas and air impermeability

  • has good weather, ozone and embrittlement resistance

  • good resistance to diluted acid and salt solutions and is considered flame retardant

  • swells strongly on contact with aromatics

  • Temperature resistance: -40°C to 120°C

Chloroprene rubber has excellent weather resistance and is resistant to many chemicals, including acids and bases 000-0000-000000000111_Mineral oils and lubricants on what it is for Use in outdoor applications, such as in the construction industry, makes it interesting. Besides CR has unique flame-retardant and insulation s properties, which means it is used primarily in electronic or fire-protected components e.g. in the automotive industry or in the security sector or housing construction used_11100000-0000-0000-0000-00000 0000111_will. ​ flexibility Neoprene exhibits excellent flexibility and elasticity, making it adapt well to various shapes and movements.   Tear resistance High tear resistance makes neoprene resistant to mechanical stress and ensures a long service life in demanding applications.   Wear resistance Neoprene has good wear resistance, making it particularly suitable for applications in the construction and automotive industries, such as vehicle tire seals and treads.   density The density of neoprene is moderate, allowing for a balanced combination of strength and weight. This makes it useful in applications where a certain lightness of the material is desired.   Insulation properties Neoprene shows very good insulating properties, especially in the electrical area. It is often used in the electrical industry for cable jacketing and insulation.   Weather resistance Neoprene is particularly resistant to weather influences, UV radiation and ozone, which makes it suitable for outdoor use, e.g. B. in seals and covers, makes it ideal.   Chemical resistance It shows good resistance to oils, fats and many chemicals, which is why  It is often used for applications in the chemical industry.   Temperature resistance Neoprene remains stable even in extreme temperatures, making it suitable for applications in the electrical industry, refrigeration and automotive engineering.   Water resistance Neoprene is resistant to many substances dissolved in water, including salt water. This property makes it particularly useful in maritime applications, water filtration technology and areas with increased humidity. ​ Flame resistance CR is naturally flame retardant and retains its mechanical properties even when exposed to fire.

Material hardness and coloring


CR is available in different degrees of hardness, ranging from soft (40° Shore A) to harder types

(above 90° Shore A) is sufficient. This range allows adaptation to a wide range of requirements and applications, from flexible seals to rigid structures. In terms of color schemes, CR is usually available in black or various shades of grey. Color options are very limited compared to some other elastomers.


Industries and applications

Chloroprene rubber is a versatile elastomer with outstanding material properties.

Its weather resistance, oil resistance and chemical resistance make it a valued material in industries such as the automotive industry, construction industry, electrical industry and many others.

Automotive industry Neoprene is widely used in the automotive industry, particularly for seals, hoses, shock absorbers and other components due to its oil resistance and flexibility. Construction industry Due to its weather resistance, neoprene is used in the construction industry for caulking, window seals and various sealing applications. Electrical industry CR is used in the electrical industry for cable insulation and wire coating due to its good electrical insulation properties. Sports and leisure products Neoprene is the main material used in the production of diving suits, water sports suits, gloves and other sports and leisure products due to its flexibility, durability and water resistance. Industrial sealing applications Because of its versatility and durability, neoprene is used in a variety of industrial sealing applications, including food and chemical processing.

Chloroprene rubber impresses with its excellent weather and ozone resistance as well as a wide temperature tolerance, which makes it particularly ideal for use outdoors and at different temperature extremes. Neoprene also has oneincomparable Water resistance and is used by engineers

valued for its flame-retardant and insulating properties.

targeted material selection

Due to the high level of wear and tear on rubberand plastic products, the associated complex repair work and expensive downtime, we clarify all the physical aspects in the first conversation

and chemical influences on the product.


This allows us to offer our customers high-quality products

withoffer the best durability and resistance.


Material optimization

We optimize the physical and chemicalCharacteristics

of the material used or are specifically looking for alternatives,

to provide better resistance to different 

environmental influences. 


This allows us to identify your product using data sheets,Attempts or external tests to specifically improve the quality.
