AFLAS® 与 FKM (Viton®) | AFLAS® 与 FFKM(Kalrez®、Chemraz®、Simriz® 等) |
AFLAS® O 形圈比 FKM 具有更好的耐碱性和耐蒸汽性。 | AFLAS® O 形圈具有与 FFKM 类似的耐化学性,是一种更具成本效益的材料。 |
AFLAS® O 形圈应用
凭借其独特的耐化学性以及相对于 FFKM 的成本优势,AFLAS® 在各个行业中的应用不断增加。
应用 | 好处 | 描述 |
---|---|---|
Downhole | Chemical Resistance, Heat Resistance, Steam Resistance | In certain geographic regions, O-rings used downhole are exposed to corrosive gas like H2S, high temperature steam, or basic mud. Rubber parts made of AFLAS® survive longer under these harsh conditions. |
General Steam | Steam Resistance, Anti-Corrosive | FKM will harden if it comes into contact with steam which contains even a very small amount of anti-corrosive. AFLAS® has excellent steam resistance and has been found extremely reliable in this application. |
Mechanical Seals | Amine, Alkali Chemical Resistance | O-rings in mechanical seals are required to be resistant to various chemicals in one environment. AFLAS® has superior chemical resistance compared to FKM. |
Marine Engines | Anti-Corrosive | Coolant inside large diesel engines contains anti-corrosive additives, and some of these can damage FKM. Because of this, a higher cost FFKM is sometimes used. However, leakage problems can often occur due to the poor elasticity of FFKM. AFLAS® has similar chemical resistance to FFKM and better elasticity. AFLAS® not only has a cost advantage but also a longer service life in this kind of application. |
