EPDM seal mechanical seal for sealing teach you the material requirements and uses
EPDM sealing strip seal products are manufactured windows and doors seal, automotive seals, train seals, cabinet seal, ship seal strips. Material is divided into EPDM sealing strip, PVC rubber seal, silicone seal, TPE seal, TPV seals, nitrile rubber seals, polyurethane sealing strips sealed different media, as well as equipment The working hypothesis is different sealing materials having different required adaptability. Sealing material shall meet the requirements of the sealing function of the sealing material requirements generally:vehicle seals
1, material density, and not leaking medium
2, a suitable mechanical strength and hardness
3, compressibility and good elasticity, permanent deformation
4, does not soften at high temperatures, decomposition, do not harden at low temperatures, do not rattle
5, anti-corrosion properties, and the acid, alkali, oil, medium to long-term, small changes in the volume and hardness, and does not adhere to the metal surface
6, the friction coefficient is small, good abrasion resistance combined with the softness of the sealing surface
7, good resistance to aging, durable
8, manufacturing convenient, cheap, easily drawn.
Rubber is the most common sealing material. In addition to the rubber, the material is suitable as well as sealed graphite, PTFE and a variety of sealant.tamper evident tapes
