Product Details

High Temp Resistant Green Color Fkm Round O Ring Sealing O-rings

High Temp Product Description

All rubber is subject to deterioration at high temperature. Volume change and compression set are both greatly influenced by heat. Hardness is influenced in a rather complex way. The first effect of increased temperature is to soften the compound. This is a physical change, and will reverse when the temperature drops. However, it must be considered in high pressure applications because a compound that is sufficiently hard to resist extrusion at room temperature may begin to flow and extrude through the clearance gap as the temperature rises, due to this softening effect.
With increasing time at high temperature, chemical changes slowly occur. These generally cause an increase in hardness, along with volume and compression set changes as mentioned above. Changes in tensile strength and elongation are also involved. Being chemical in nature, these changes are not reversible.Therefore, the corresponding materials are needed to make better products.

FKM:FKM has excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance. It has been widely used in aerospace, aviation, automotive, petroleum and household appliances, and is an irreplaceable key material in cutting-edge defense industries

FKM advantage:

1 . Excellent stability :FKM has a high degree of chemical stability and is the best medium resistance of all elastomers

2 . high - temperature resistance :The high temperature resistance of fluorine rubber and silicone rubber , can be said to be the best elastomer .

3 . ageing resistance :Fluorine rubber has excellent weathering resistance and ozone resistance.

4 . Excellent vacuum performance.

5 . Excellent physical and mechanical properties

6 . The solubility of the gas is relatively large, but the diffusion speed is relatively small, so the overall performance of the air permeability is also small.

FKM has the characteristics of high temperature resistance, oil resistance, high vacuum resistance, acid and alkali resistance, and a variety of chemical drugs. It has been applied to modern aviation, missile, rocket, space navigation, naval ships, atomic energy and other cutting-edge technologies and automotive, shipbuilding, chemical, petroleum, telecommunications, instruments, machinery and other industrial fields.

FFKM o-rings are the highest high-performance family of o-rings with the highest temperature (up to 620F) and ultimate chemical resistance. FFKM o-rings are specifically manufactured for extreme applications where up time performance is worth the significantly higher cost compared to other basic materials.
