Acrylic Fibres

Acrylic is a versatile and high-performance material that can be used in a huge number of applications from construction to textiles. Acrylic fibres are used to improve the properties of a wide range of industrial products.

This rigid thermoplastic material is resistant to most solvents and chemicals, heat resistant, slow to burn, and is almost impermeable to gases.

Made from polyacrylonitrile polymer, acrylic fibres are made from mixtures which have >85% acrylonitrile content. These fibres are well known for their intumescent properties and as the chemical precursor of high-quality carbon fibre.

Precision cut acrylic fibres

Because of their excellent heat and chemical resistant properties, precision or short cut acrylic fibres are used for reinforcement in a wide variety of industrial applications. These include the manufacture of adhesives, castings, composites, filters, lead acid battery plates, paints, paper, sealants, and refractories. Due to its rigidity, acrylic fibres are also commonly chosen to prevent or repair cracking or to avoid sagging or distortion of final industrial products.

Our precision cut acrylic fibres are available in a range of sizes, but the most common are:

  • 3.30 decitex
  • 6.70 decitex

Milled acrylic fibres (flock)

Milled acrylic fibres, also known as random length or ground flocks, are polyacrylonitrile fibres that are widely used to improve the properties of a wide range of industrial products. The addition of a controlled amount of acrylic flocks can achieve a number of benefits. For example, milled acrylic fibres can reinforce and add strength and abrasion resistance to a product while drying, curing, or vulcanising, as well as preventing the formation of micro-cracks that can ultimately reduce the integrity of a product.

Acrylic fibre flock is also used in fire resistant paints for safety reasons and improved coverage. It has high thermal stability and charring properties which, when exposed to fire, prevent slumping of paints, reduce cracking, and increase fire protection time, without cost and REACH implications.

Acrylic fibre flock is also used as an alternative to asbestos for the manufacture of brake pads and clutch plates.

Depending on the application, we can produce milled acrylic fibres in a range of sizes, but the most commonly used are:

  • < 500 microns
  • 1001 – 5000 microns
