Our Guide To ACM – Acrylic Rubber

Polyacrylic rubber, also known as ACM, are manufactured elastomers that are created from acrylic monomers. ACM is created through a process of emulsion or suspension polymerisation, which is designed to make these moulded rubber components suitable for use in the most testing environments.

What Is ACM Rubber?

What Are The Advantages Of ACM Rubber?

It has an array of properties that make it suitable for use in a range of hard-wearing applications. The key feature of ACM is its incredibly high resistance to hot hydraulic oil and oxidation, making it ideal for use in hydraulic machinery and equipment. Furthermore, ACM is naturally resistant to ozone and weathering, which makes it far superior to nitrile rubber (NBR).

What Are The Disadvantages Of ACM Rubber?

Despite ACM being well suited to a range of applications, particularly environments that face weathering and environmental pressures, this rubber will not be well suited to environments that face large amounts of water and rain damage. This is due to ACM having poor water resistance, as well as low resistance to low temperatures. This moulded rubber solution is only suitable in applications as low as -10°C. Also, ACM has a poor level of resistance to acids and alkalis.

Additionally, ACM does have a very low resilience in temperatures below 70°C. However, despite this, it has found use in vibration damping.

What Are The Typical Applications Of ACM?

Typical applications for ACM include:

  • Automotive Components
  • Textiles
  • Adhesives
  • Coatings

What Temperatures Does ACM Suit?

ACM has a typical working temperature range from -10°C to 150°C.
