AFLAS O-Rings | Global O-Ring and Seal

美国最大的 AFLAS® O 型圈库存之一

Global O-Ring and Seal 库存有标准和公制尺寸的 70、80 和 90 硬度计的 AFLAS® O 型圈。Global O-Ring and Seal 拥有全系列（所有 394 个 AS568 尺寸）的AFLAS® 80 硬度计黑色 O 型圈。

AFLAS® 是四氟乙烯 (TFE、FEPM) 和丙烯的共聚物，也称为 TFE/P。这种弹性体由旭硝子 (日本) 开发，并以 AFLAS® 商品名销售。

AFLAS® O 形圈对多种化学物质具有很强的抵抗力，例如酸、碱和蒸汽。

标准低温：-10°C (-14°F)
标准高温：220°C (428°F)

标准低温：0°C (32°F)
标准高温：250°C (482°F)

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，并且是一种更具成本效益的材料。

由于其独特的耐化学性，以及相对于 FFKM 的成本优势，AFLAS® 在各个行业中的应用越来越广泛。

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.
