2014年7月3日 · Dupont’s Viton ETP® fluoroelastomer is a peroxide-cured FKM designed for extreme applications. ETP® gives resistance to fuel, solvents, acids, bases and amines, while also providing a good working temperature range of -25’C to 200’C. Viton ETP® is just a polymer base, so compounding of the rubber still applies.

etp 氟橡胶既有普通 fkm 良好的耐高温性能，又具有突出耐化学性能； ETP 氟橡胶在酸类，碳氢化合物和低分子量的酯类，酮类和醛类介质中具有良好的抵抗性能；

Viton™ 氟橡胶主要有四大系列：A、B、F 和 ETP，它们各有其独特的性能特征。 Viton™ 产品系列之间的一个主要区别是基于聚合物氟含量的流体阻力。 这种特性由组成聚合物的特定单体的类型和相对数量所决定。

Viton™ Extreme™ ETP-600S is a copolymer of ethylene, tetrafluoroethylene (TFE), and perfluoromethylvinyl ether (PMVE). This unique combination of monomers provides outstanding resistance to harsh fluids. Viton™ Extreme™ ETP-600S exhibits the same excellent resistance to acids and hydrocarbons typical of A, B, and F types of Viton™ fluoroelastomers.

氟橡胶 (FKM, Viton™)氟橡胶是一种众所周知的高性能橡胶，尤其具备绝佳的耐高温、耐臭氧、耐气候、耐氧化、耐矿物油、耐燃料油、耐液压油、耐芳香族与许多有机溶剂和化学物的性质。

Viton® ETP O-Rings also known as Viton® Extreme O-Rings provide significantly improved chemical resistance compared to standard Viton® A type fluoroelastomers. Viton® ETP is so chemically resistant it can be considered a cost-effective Kalrez® alternative for some applications with temperatures below 400°F.

Viton™ Extreme ETP has 67% fluorine content and is composed of ethylene perfluoro-methyl vinyl ether (PMVE) and tetrafluoroethylene (TFE) with a peroxide cure site monomer. In addition to the high-temperature resistance, Viton™ Extreme ETP offers excellent protection to acids, hydrocarbons, esters, ketones, aldehydes, and high pH fluids.

2025年2月3日 · Viton®的工作温度范围为-20°F（-29°C）至450°F（232°C），且可间歇性暴露至500°F（260°C）的温度。然而，由于其卓越的性能，Viton®的价格明显高于Buna和EPDM。另外，Viton®的其他等级如Viton® GF和Viton® ETP提供了更强的化学耐受性。

由于 FKM 具备绝佳的耐高温、耐油、耐溶剂、耐燃、耐化学物与耐气候的性质，通常用于汽车业、化学领域、航天和许多工业上。 Viton GLT 具备更广的使用温度范围，温度从 -45℃ 至 +275℃，且具备出色的耐极具侵略性的 HTS 型矿物油，因此常用于航天领域。 Viton ETP 通常应用于化学工业领域。 材料列表.
