The physical benefits of rubber air springs after vulcanization
Guomat air spring bladder has improved physical properties during vulcanization, including strength (tensile strength, tensile strength and tear strength, etc.), elongation at break, hardness, density, breathability, elasticity, permanent deformation, swelling, etc.
1. Solubility: During the vulcanization process, the ability of the rubber to dissolve in the solvent will gradually decrease, but it can only swell; after vulcanization for a certain period of time, the swellability will show a minimum value, and the vulcanization will gradually increase the swellability.
2. Thermal stability: Vulcanization improves the thermal stability of the rubber and reduces the influence of the external temperature difference on the performance of the air spring, such as crystal hardening, viscous flow, decomposition and other problems. Guomat continuously accumulates customer feedback data, actively cooperates with customer needs, tailor-made air springs, and wins unanimous praise from users.
3. Density and air permeability: Within a certain vulcanization time range, with the increase of crosslinking density, the rubber density increases, while the air permeability decreases with the increase of crosslinking density. This is very important for the use of air springs. The lower the air permeability, the less gas escapes during use, the higher the stability of the air spring, and the lower the frequency of pumping.
