产品概述

FE710 是一款专为密封应用设计的高性能三元乙丙橡胶材料，具备优异的耐候性、耐臭氧性和耐高低温性能，同时拥有良好的弹性与抗老化能力，是户外及恶劣环境工况的优选密封材料。

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. 耐候抗老化性能优异：三元乙丙橡胶的分子结构不含双键，对臭氧、紫外线和环境老化的抵抗能力极强，长期户外使用不易出现龟裂、脆化问题，使用寿命远优于通用橡胶。

2. 宽泛的耐温性能：可在-50℃至150℃的宽温域环境中稳定工作，低温下仍能保持良好弹性，高温工况下也能维持可靠的物理性能，适配多种极端温度场景。

3. 可靠的密封稳定性：100℃下22小时压缩永久变形为23%，在高温压缩工况下仍能保持较好的弹性回复性，可有效降低长期使用中因永久变形导致的泄漏风险。

4. 标准级品质管控：所有性能指标均通过ASTM/ISO国际标准方法测试，批次稳定性高，可满足批量工业生产的一致性要求。

核心性能特点

· 硬度：71 Shore A，测试标准 ASTM D2240

· 密度：1.17 g/cm³，测试标准 ISO 2781

· 100%定伸模量：5.03 MPa，测试标准 ASTM D412

· 拉伸强度：14.12 MPa，测试标准 ASTM D412

· 拉断伸长率：295 %，测试标准 ASTM D412

· 压缩永久变形（22h@100℃）：23 %，测试标准 ASTM D1414

· 最高工作温度：150 ℃

· 最低工作温度：-50 ℃

典型应用领域

FE710三元乙丙橡胶凭借优异的耐候、耐水、耐酸碱性能，广泛应用于：

- 户外设备、建筑门窗的防水密封件

- 汽车冷却系统、空调系统的耐水/耐蒸汽密封件

- 家电卫浴、水处理设备的耐酸碱密封部件

- 对耐臭氧、耐老化有高要求的工业密封场景

补充说明

本材料为黑色EPDM三元乙丙橡胶，硬度71 Shore A，适配绝大多数标准密封件结构。实际使用时，需结合具体介质、压力和工况温度进行兼容性验证，以确保长期使用可靠性。
