AFLAS O-Rings | Global O-Ring and Seal

美国最大的AFLAS®O型圈库存之一

全球O型圈和密封件备有标准尺寸和公制尺寸的70、80和90硬度计的AFLAS®O型圈。整体O形圈和密封圈保持AFLAS®80 Durometer黑色O形圈的全线（所有394 AS568尺寸）。

AFLAS®是四氟乙烯（TFE，FEPM）和丙烯的共聚物，也称为TFE / P。该弹性体由日本旭硝子开发，并以AFLAS®商标出售。

AFLAS®O形圈对各种化学品（例如酸，碱和蒸汽）具有很高的抵抗力。

标准低温：-10°C（-14°F）
标准高温：220°C（428°F）

AFLAS®与FKM（Viton®）	AFLAS®与FFKM（Kalrez®，Chemraz®，Simriz®等）
与FKM相比，AFLAS®O形圈具有更好的耐基性和耐蒸汽性。	AFLAS®O形圈与FFKM具有相似的耐化学性，是一种更具成本效益的材料。

凭借其独特的耐化学性以及与FFKM相比的成本优势，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.
