矽橡膠熱縮套管與氟橡膠熱縮套管有哪些區別

橡膠材質的熱縮管有矽橡膠熱縮套管、乙丙橡膠熱縮套管以及氟橡膠熱縮套管等,從外觀來看矽橡膠熱縮管與氟橡膠熱縮管沒有太大的區別,其特點柔軟,耐高低溫,有彈性等也幾乎類似,所以二者幾乎可以互為替代品,那麼矽橡膠熱縮套管與氟橡膠熱縮套管究竟有哪些區別呢?
1.構成要素區別:
   
矽橡膠熱縮套管由橡膠和高分子彈性體經輻射改性製成,可長期在高溫下使用,耐酸堿、耐溶劑、耐外界機械破壞。可用于軍工車輛、高鐵動車、艦船設備或電機電器等行業的線纜終端、分離結合處的防護。
   
氟橡膠熱縮套管由氟橡膠和高分子彈性體經輻射改性製成,可長期在高溫下使用,耐柴油、航空燃油、耐高溫流體。可用于軍工車輛、高鐵動車、艦船設備或商用線纜終端、分離結合處等的防護。

2.收縮倍率區別
    氟橡膠熱縮倍率為2:1,矽橡膠熱縮倍率為1.7:1;也就是說氟橡膠熱縮管的拉伸強度高於矽橡膠熱縮管。
3.使用溫度區別
    無論是矽橡膠熱縮管還是氟橡膠熱縮管,其收縮溫度都是90170;但是使用溫度上氟橡膠熱縮管耐低溫到-65,矽橡膠則為-55
4.特徵區別
    氟橡膠熱縮套管相比於矽橡膠熱縮套管耐油、耐化學溶劑能力更好。

What is the difference between Silicone rubber heat shrinkable sleeve and fluoro rubber heat shrinkable sleeve

The heat-shrinkable tube made of rubber has a rubber heat shrinkable sleeve, an ethylene-propylene rubber heat shrinkable sleeve, and a fluororubber heat shrinkable sleeve. From the appearance, the rubber heat shrinkable tube is not much different from the fluororubber heat shrinkable tube. Its characteristics are soft, high temperature resistant, elastic and so on, so the two can be substitutes for each other. So what is the difference between the rubber heat shrinkable sleeve and the fluororubber heat shrinkable sleeve?
1. Differences in constituent elements:
Silicone   Rubber heat shrinkable sleeve is made of rubber and polymer elastomer by radiation modification. It can be used at high temperature for a long time, resistant to acid, solvent and external mechanical damage. It can be used for the protection of cable terminals and separation joints in military vehicles, high-speed rail trains, ship equipment or electrical machinery.
The fluororubber heat shrinkable sleeve is made of fluororubber and polymer elastomer by radiation modification. It can be used at high temperature for a long time, and is resistant to diesel, aviation fuel and high temperature resistant fluid. It can be used for protection of military vehicles, high-speed rail trains, ship equipment or commercial cable terminals, separation joints, etc.

2. Shrinkage ratio difference
The heat shrinkage ratio of the fluororubber is 2:1, and the heat shrinkage ratio of the ruthenium rubber is 1.7:1; that is, the tensile strength of the fluororubber heat shrinkable tube is higher than that of the Silicone rubber heat shrinkable tube.
3. Use temperature difference
Whether it is a rubber heat-shrinkable tube or a fluororubber heat-shrinkable tube, the shrinkage temperature is 90 ° C ~ 170 ° C; but the temperature of the fluoro rubber heat shrinkable tube is resistant to low temperature to -65 ° C, and the Silicone rubber is -55 ° C.
4. Feature difference
The fluororubber heat shrinkable sleeve has better oil and chemical resistance than the bismuth rubber heat shrinkable sleeve.
