CR rubber is Chloroprene rubber, otherwise Neoprene is a polymer of chloroprene. It is one of the first synthetic rubbers. It is distinguished by above-average resistance to ozone. It is also resistant to weather conditions and many chemicals. He is also indifferent to flames. It is characterized by good mechanical properties and a wide range of operating temperatures. Thanks to its properties, it is readily used in many industries and industries.
What does the abbreviation CR stand for?
CR abbreviation comes from the English language. Means chloroprene ruber. In Polish, it is chloroprene rubber.
Chloroprene rubber – properties
It is thanks to the wide range of properties that it is widely used in many industries. It is resistant to any wear. It is characterized by high abrasion resistance. Chloroprene rubber is also distinguished by high resistance to many chemical compounds, such as:
- Paraffin-based mineral oils and silicone lubricants
- Water and aqueous solutions at medium temperatures
- Refrigerants such as: ammonia, CO2, freon
- Aging in weather conditions (resistance higher than natural, isoprene or sterine-butadiene rubber)
- Alcohols and glycols
It has medium resistance to naphtha based mineral oils, short chain aliphatic hydrocarbons such as propane, butane and fuels, and glycol based brake oils.
However, chloroprene rubber is not resistant to:
- Aromatic hydrocarbons, e.g. benzene
- Chlorinated hydrocarbons, e.g. trichlorethylene
- Polar solvents such as acetone, esters and ketones
- Petroleum fuels
- Gas permeability
Its temperature range of operation ranges from -40 degrees, up to + 110 degrees. Krótkotrwale nawet do +130 degrees. This is why it is so readily used in many industries. Chloroprene rubber is also flexible at temperatures down to about -40 degrees.
However, it is worth remembering that when storing it at a temperature below 0 degrees. Celsius, during the ongoing crystallization process, an irreversible stiffening process takes place.
The trade names under which chloroprene rubber is hidden are:
- Du Pont
- Denka Chloroprene
Neoprene rubber – application
The wide spectrum of neoprene rubber properties allows it to be widely used in many industries. It works especially well in the electronic and automotive industries. Chloroprene rubber with an appropriate certificate can also be used in contact with food products. Also used in the processing of fruit and vegetables. It will also be used in refrigeration, brewing and dairy. It will work well in storing food. CR rubber can also be used to seal drinking water systems. In addition, it is also used in the production of protective clothing, cold water hoses, axle rings, and paper gumming. We can also find it in the composition of road paints and adhesives. It is used in both light and heavy industry.
