What Do I need To Qualify For A Propane O-rings?

The use of propane o-rings are very extensive, and its working environment is also complex and diverse, which requires its compound to have some special properties. In the hydraulic system, to have good oil resistance, temperature resistance, low compression permanent deformation and a certain tensile strength. As a dynamic seal, in addition to the requirements, the compound should also have good wear resistance and tear resistance. For the sealing of special medium, the change of volume and hardness of rubber in the medium is less.

Propane o-rings are suitable for all kinds of mechanical equipment, in the specified temperature, pressure, as well as different liquid and gas medium, static or moving state of the seal. In sanitary ware, ships, automobiles, hardware, electronics, toys, electrical appliances, aerospace equipment, machinery, as well as various instruments and meters, a large number of applications of various types of sealing components. Rubber o-ring is mainly used for static seal and reciprocating seal. When used for Rotary Movement seal, it is limited to low speed rotary seal device. Rubber o-ring is generally installed in the outer circle or internal circle section of the rectangular groove to play a sealing role. Rubber o-ring in oil-resistant, acid-base, grinding, chemical erosion and other environments still play a good seal, damping role. Therefore, rubber o-ring is one of the most widely used seals in hydraulic and pneumatic transmission systems.

In general, the rubber formula is composed of raw rubber, vulcanized antioxidant reinforcing agent system, protective system, reinforcing system, softening system. The aim of formulation design is to seek the best combination of various compounding components so as to obtain good comprehensive performance. A proper propane o-ring would have to meet these conditions:

1. Must meet the performance requirements of the seal ring.

2. Secondly, the processing properties of the compound should be good.

3. And in the premise of ensuring product quality, try to choose cheap, rich sources, non-toxic or low-toxic, stable performance of raw materials.
