Adhesion

There are many conditions that can affect the adhesion of rubber to various substrates such as metal and fabrics. Commonly evaluated in tires, adhesion is also used as a common property in a wide range of other rubber products.

Adhesion testing is a critical aspect of multi-component rubber products, and frequently should be considered for both rubber to rubber interfaces and rubber to reinforcement interfaces.

Several methods can determine the force required to separate rubber from a material:

  • Shear testing of reinforcements to rubber adhesion
    • Steel cord
    • Bead wire
    • Textiles: nylon, polyester, rayon and polyaramids
  • Quadruple shear method for adhesion to rigid plates
  • Fracture tear / peel force adhesion testing of rubber-rubber interfaces
  • Fracture tear / peel force adhesion testing of rubber-to-rigid surfaces
  • Roller peel adhesion testing
  • Strebler tear adhesion testing
  • 90° peel for adhesion to metal
  • Two plate method for adhesion to textile fabrics

Our labs are equipped with six universal testing machines, covering a calibrated load range of 1N upto 250kN. Our testing machines are supported by an extensive range of sample grip combinations.

Sample Preparation

Our extensive sample preparation facilities can test a huge variety of materials and product forms and are equipped with a CNC machine, on-site moulding, and slitting and buffing equipment to reduce rubber thickness.

Environmental Capability

Additional environmental chambers enable our experts to conduct testing in a temperature range from -50°C to 200°C.

Common Test Protocols

ASTM D413

Adhesion to Flexible Substrates Testing - This test method measures the force required to separate a flexible material (fabric, fiber, etc.) from a rubber layer.

BS ISO 813

Adhesion to a rigid substrate - 90° peel (vulcanized rubber or thermoplastic).

BS ISO 814

Adhesion to metal – two plate method (vulcanized rubber or thermoplastic).

BS ISO 36

Adhesion to textile fabrics (vulcanized rubber or thermoplastic).

BS ISO 1827
