Rubber Adhesion Test

D378 10 2016 standard test methods for rubber elastomeric conveyor belting flat type.

Rubber adhesion test.

There are many conditions that can affect the adhesion of rubber to various substrates such as metal and fabrics. At white cross rubber products we use a variety of testing methods to ensure the quality of our products. The acceptable value of adhesion measured will of course vary from product to product due to different rubber formulations flexible substrates and types of products. 4 1 these test methods are used to ensure the quality of a product by determining the force per unit width required to separate a rubber layer from a flexible substrate such as fabric fibre wire or sheet metal.

The standard requires that the testing machine conform to practices described in astm e4. Ardl offers a variety of tests to evaluate the adhesion properties of materials and components. A standard method for the application and performance of this test is available in astm d6677. Rubber hose and belting.

Adhesion testing for rubber adhesion to flexible and rigid substrates as well as the adhesive bonding of parts are an important properties for designers to understand when evaluating materials. From peel or stripping strength to measurements at temperature ardl can provide the. This test standard is divided into methods a through h. The acceptable level of adhesion will vary from on.

The brittle ductile transition phenomenon is very important in polymer appli. D816 06 2016 standard test methods for rubber cements. 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. Common application examples that use tests in astm d429 are vehicle engine mounts vehicle suspension bushings rubber coated metal parts and rubber lined tanks and containers.

Astm d429 determines the adhesion strength of rubber to rigid materials such as metals. There is no known correlation to other adhesion test methods pull off tape etc. Pressure sensitive tape is applied and removed over cuts made in the coating. Astm d429 test standard determines the adhesion of rubber to rigid metal substrates.

On metal substrates a more formal version of the knife test is the tape test.
