产品概述

O型圈是安装于密封沟槽内、适量压缩的O型截面密封环。在各类动密封与静密封工况中，O型圈是高效且经济的通用密封元件。产品采用模压成型，尺寸通常以内径 d1和截面直径d2定义（见尺寸图）

尺寸图

· 美国标准AS568，线径有1.78mm、2.62mm、3.53mm、5.33mm、6.99mm，内径有1.24mm~658.88mm的大部分规格

· 中国标准GB3452.1，线径有1.8mm、2.65mm、3.55mm、5.3mm、7mm，内径有1.8mm~670mm的大部分规格

· 日本标准JISB2401P系列，线径有1.9mm、2.4mm、3.5mm、4.5mm、5.7mm、8.4mm，内径有1.8mm~1499.50mm的大部分规格

材料特点

1. KR715 全氟醚橡胶 (FFKM) —— 极端工况下的高性能密封解决方案

2.KR715 是一款优质的全氟醚橡胶（Perfluoroelastomer, FFKM）材料，兼具优异的耐高温、耐化学腐蚀与低压缩永久变形特性，专为半导体、化工、石油天然气及航空航天等严苛环境设计。

核心性能特点

· 超宽工作温度范围：-15℃ 至 +230℃，可在极热与极寒环境中保持稳定弹性。

· 卓越的化学兼容性：耐受几乎所有的化学品，包括强酸、强碱、有机溶剂、醚类、酮类及燃油等。

· 优异的力学性能：拉伸强度 ≥17.64 MPa

断裂伸长率 ≥188%

100% 定伸模量≥7.31 MPa

· 低压缩永久变形：17%，确保长期密封力保持，减少泄漏风险

· 硬度 (Shore A)：75，兼顾良好密封应力与装配便利性

典型应用领域

半导体制造：等离子刻蚀、化学气相沉积（CVD）、湿法清洗等工艺中的密封件、阀门隔膜。

化工与石化：高温酸/碱介质中的泵、反应釜、管道密封。

石油天然气：井下工具、阀门、密封组件，耐受硫化氢、胺类等腐蚀性流体。

航空航天：燃油系统、液压系统、发动机高温区域密封。

制药与食品：需耐清洗剂、蒸汽消毒的静态密封。
