Testing & Instruments

Tensile testing is arguably the most common test method used in both force measurement and material testing. Tensile testing is used primarily to determine the mechanical behavior of a component, part or material under static, axial loading.

The C11 Wallace compression stress relaxometer allows flexibility and enables different samples over varying time periods to be tested.

Changes in compound chemistry are evaluated differently based on the chosen abrasion test and on the immediate test settings used.

Machine learning methods are used to explore the potential of mold breathing for quality assurance in rubber injection molding.

Products produced by anionic polymerization of nonpolar monomers, such as polybutadienes (BR), polyisoprenes (IR), solution styrene butadiene rubbers (SSBR) and styrenic block copolymers (SBC), already dominate important positions in industries. Examples include thermoplastic elastomers, adhesives, impact modifiers, lubricant modifiers, vulcanized compounds, asphalt modification and others. SBCs combine the properties of a thermoplastic resin, polystyrene and those of an elastomer, polybutadiene, polyisoprene or poly(ethylene-co-butylene). SBCs derive their useful properties from their ability to form distinct styrene (hard phase) and diene (rubber phase) domains

Research on the mechanism of tire wear and its rubber test methods has been carried out for more than a century, ever since the advent of pneumatic tires, and there are still numerous new reports being published even now. ISO 23794:2015 standardizes the general outline of 14 types of rubber wear test methods, such as the Akron wear test, the Lambourn wear test and the DIN wear test. The Akron wear test and Lambourn wear test, which introduce slippage between the pavement surface and the rubber sample, are suitable for evaluating tire tread wear resistance. Historically, Lambourn was the first to propose a laboratory wear tester that correlated with tire wear test results
