产品名称:三元乙丙O型圈EPDM ORing-澳门威尼斯人注册58
产物 编号:
产品规格:
产品类别:O型圈ORing
放大检察:威尼斯vn99
产物阐明:
 

EPDM

EPDM 弹性体具有超强的拉伸强度和卓着的耐候性和耐臭氧性及耐化学腐蚀性。也具有卓着的电绝缘性。 过氧化物 加工的弹性体具有卓着的耐老化性和从 –40 +150°C 的耐压缩变形,若是加工  ,则机能更强。它们抗多种介质,包孕热水和 200°C 的蒸汽(缺少氛围),但不思索取矿物质和分解润滑油及碳氢燃料的兼容性。它们常用于消费窗户和门密封件、电线和电缆绝缘材料、防水板和软管、密封件、O -威尼斯人app下载型圈和垫圈。

 

长处

瑕玷

过氧化物

比硫加工的弹性体更具耐热性。
更好的耐压缩变形。
过氧化物加工的质料一般更适用于保存密封力极其主要的运用中。示例为 O 型圈和密封件。
过氧化物加工的部件更干净,更适用于食物和制药运用

比硫加工的弹性体具有更强的拉伸强度、断裂和扯破伸长强度。
关于如 O 型圈如许的密封元件来讲,这些属性不是最重要的。

比过氧化物加工的弹性体具有更好的拉伸强度、断裂和扯破伸长强度。

更强的耐压缩变形。
更低的耐热性。

 

 

EPDM

EPDM elastomers have a fair tensile strength and excellent resistance to weathering and ozone, and chemical attack. They also exhibit excellent electrical insulation properties. Peroxide cured elastomers exhibit excellent heat ageing, and resistance to compression set from 40 to +150°C, more so if sulphur cured. They are resistant to a wide range of media, including hot water and steam to 200°C (in the absence of air), but are not considered compatible with mineral and synthetic lubricants, and hydrocarbon fuels. They are typically used in the production of window and door seals, wire and cable insulations, waterproofing sheets and hoses, and seals, O-rings and gaskets.

 

ADVANTAGES

DISADVANTAGES

Peroxide

Much better heat resistance than sulphur-cured elastomers.

Better compression set resistance.

Peroxide-cured materials are normally better where retained sealing force is important. Examples are O-rings and seals.

Peroxide cured parts are considered cleaner for food and pharmaceutical applications.

Poorer tensile strength, elongation at break and tear strength than sulphur-cured elastomers.

These properties are not nromally the most important for sealing elements like O-rings.

Sulphur

Better tensile strength, elongation at break and tear strength than peroxide-cured elastomers.

Poorer compression set resistance.

Lower heat resistance.
