Insertion Rubber

Insertion Rubber Roll

Insertion rubber is a type of rubber which is reinforced by layers of fabric which are “inserted” into the rubber. This internal layer of fabric is usually made of nylon or polyester and helps to increase the tensile strength and the tear resistance of the material. The fabric insert also reduces the elasticity of the plastic meaning that the material will better retain its original shape. Insertion rubbers offer similar properties to standard commercial rubber but are more durable and offer better wear resistance as they won’t stretch or tear.

Insertion rubber is reliable and long lasting and is often used in extremely abrasive applications such as guards on farming machinery. Insertion rubber is often made using SBR and natural rubber with fabric inserts. For applications where oil and fuel resistance are necessary, it is recommended to use neoprene or nitrile insertion.

Insertion rubber is often cut into gaskets, washers, strips, or pads or manufactured to make sleeves. Insertion rubber sheets are available in a range of thicknesses and with varying amounts of fabric reinforcement. The number of ply refers to the number of fabric layers within the insertion rubber. For example, 5 ply insertion rubber contains 5 layers of reinforcing fabric within the material.

Key Properties of Insertion Rubber:

  • Similar properties to standard commercial rubber
  • Excellent tensile strength
  • Excellent tear resistance
  • Low elasticity

Typical Applications:

  • Applications where low cost and high wear resistance are key requirements
  • Guards on farming machinery Equestrian matting
  • Gaskets
  • Car boot mats
  • Mud flaps
  • Worktops and counters
  • Horsebox and trailer partitions
  • Seals
  • Skirtings to prevent draughts

Available Finishes: 'SS' has a smooth finish on both sides, 'CC' has a cloth-print finish on both sides and 'CS' has a smooth finish on one side and a cloth-print finish on the other.
