ACM Rubber - Acrylic Rubber

ACM Rubber is a type of acrylic rubber, which are copolymers of esters. These esters are compounds derived from acrylic acid. Rubber is produced when the esters are mixed in the production process with acrylonitrile or ethers. Polymerization of rubber occurs in an aqueous emulsion. This product then undergoes crosslinking.

What does the abbreviation ACM mean?
ACM Rubber stands for Acrylic rubber. In English, it is Acrylic rubber.

ACM is not destroyed by the presence of sulfur and chlorine in the working environment. It can be used wherever additives are used in oils and greases. Despite its high chemical resistance, ACM can deform under strong pressure. It also shows reduced tear strength.

The mechanical properties of this rubber are:

• resistant to temperatures of -20 to -40 degrees Celsius,
• this elastomer withstands a temperature load of 150 degrees Celsius,
• short-term resistance to a temperature load of 175 degrees Celsius,
• compared to natural rubber or styrene-butadiene copolymer, ACM does not reach such high strength values and is not as elastic,
• it performs well in ozone atmosphere and various weather conditions,
• resistant to hot petroleum oils, especially those containing sulfur,
• resistant to swelling.

ACM rubber is not resistant to hot water, steam, acids, and bases. It is also unstable in aromatic hydrocarbons, chlorinated environments, and brake fluids containing glycol.

Its electrical properties depend on its water absorption capacity and are therefore moderate and composition-dependent.

ACM rubber is primarily used wherever high resistance to industrial oils and work at higher temperature ranges is needed (also where hot air is used). It is often used in the automotive industry (seals), as well as in the production of O-rings, hoses, adhesives, various types of bonding agents, and coating materials. ACM is a good base for sealing compounds.

ACM Rubber - Trade Names
ACM rubber has several trade names. It can be found on the market as

• Hycar 4000
• Cyanacryl
• Alaprim AR
• Europrene
• Nipol

It is more resistant than NBR (nitrile vulcanizator) to oxygen, ozone, and oils.
