Fatigue testing of flexible porous polymer materials

Flexible porous polymer materials are light, soft, elastic, and difficult to conduct heat. They have the functions of shockproof, impact mitigation, thermal insulation, and sound insulation. They are used to manufacture automobile windshields, cushioning pads, sealing gaskets for construction projects, insulation materials for weak current components, shock-absorbing materials, simple diving suits, rubber shoes, and other products. At the same time, because of its high production efficiency and low energy consumption, it has been widely used in various fields such as industrial production and civilian homes.
The fatigue test of flexible porous polymer materials can measure the thickness loss under repeated constant deformation compression, which is used to represent the fatigue performance of flexible porous polymer materials and is suitable for quality control in the production process of flexible porous polymer materials.
Zhongke Testing Reliability Experiment Center has reliability testing capabilities for various flexible porous polymer materials and provides professional fatigue testing services for flexible porous polymer materials.

Soft sponges, hard sponges, microbubble sponges, conductive sponges, magnetic sponges, water-swellable sponges, composite sponges, NR rubber (natural rubber), SBR rubber (styrene-butadiene rubber), EPDM rubber (ethylene propylene diene monomer rubber), NBR (nitrile rubber), silicone rubber sponges, rubber sponges, rubber-plastic sponges and other sponges and rubber products.

Constant deformation is repeatedly applied to the entire surface of the specimen, and then the final thickness of the specimen is measured.
