All the rubber compounds produced are checked in our laboratory using various industry-standard tests :
Rheometry : This test measures the mechanical properties of a rubber sample as it is deformed over a range of stress, strain, time, and temperature. It can either apply stress (force) and measure strain (displacement), or apply strain and measure stress. This type of testing determines the modulus of the material (stress/strain) and controls the frequency (time) of the deformation to measure viscoelastic properties of the rubber mix.
Hardness (Shore A, IRHD, Micro-hardness) : The hardness of a rubber describes how firm or soft the material is. The hardness of an elastomer is usually determined using the Shore Hardness Scales or the International Rubber Hardness Degree (IRHD) scale. On all scales, a higher number indicates a harder material. The Shore hardness of rubber is measured with a spring-loaded indentation device known as a Shore durometer.
Dynamometric : This term is about the measuring of force or power. In the context of rubber compound testing, it refers to a variety of tests that control the force applied by the rubber mix under various conditions. For instance, a dynamometer might be used to measure the tensile strength or elongation of a rubber sample.
Ageing : Ageing tests for rubber are used to evaluate how vulcanized rubber products respond to exposure to certain conditions over time. A popular standardized test procedure for heat aging is ISO 188 : Accelerated ageing and heat resistance tests. The test is conducted on dumbbell-shaped specimens, which are placed in an oven and exposed to a prescribed temperature for a prescribed interval, usually three, seven, or 14 days.
Depending on the requirements of the specifications, we carry out all the checks on the moulded parts :
JEANTET elastomer has the resources to carry out expert assessments of defects in parts or materials.
Additional tests can be carried out in external laboratories if required.
