The experts at Smithers rubber testing labs have years of experience conducting adhesion testing for rubber and polymer materials in a wide variety of end products such as tires, hoses, and other reinforced 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. 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 methods
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

About the Labs
Our rubber testing labs are equipped with six universal testing machines, covering a calibrated load range of 1N up to 250kN. Our testing machines are supported by an extensive range of sample grip combinations. Additional environmental chambers enable our experts to conduct testing in a temperature range from -50°C to 200°C.
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.
