Performance:

Fluorine rubber heat shrinkable tube has excellent resistance to high, low temperature, acid and alkali resistance, oil-resistant rubber is the best, anti-radiation, high vacuum resistance, electrical insulation, mechanical properties, chemical corrosion resistance, ozone resistance, resistance to atmospheric aging are excellent. Oil-resistant and chemical-resistant reagent properties, especially for areas requiring heat resistance (such as electrical and hydraulic systems near aircraft or car engines or fuel tanks) and environments requiring chemical solvents, are poor processability, high price and cold resistance, and low elasticity and breathability. Use temperature range heat shrinkable tube: -20℃~+200℃.

Use:

Mainly used in the defense industry to manufacture aircraft, rockets on the vacuum resistance, high temperature resistance, chemical corrosion resistance sealing materials, hose or other parts and automobile workers. The insulation protection and stress relief of the midline cable harness in these environments protect the electrical and electronic equipment from damage.

The heat shrinkable tube foams after shrinkage: many times after shrinkage, it is found that some parts of the heat shrinkable casing blister. The main causes are:

1, did not in accordance with the requirements of the operating instructions from one end to the other end of the shrinkage or double-walled heat shrinkable tube from the middle began to shrink to both sides, such a method to help eliminate air.

2, there is no preheating of the quilt, directly the casing sleeve after the shrinkage.

3, the reason of the heat shrinkable tube itself, the radiation dose is too low, the material decomposition.

Some of the above problems are our common problems, the solution also provides a reference. Welcome customers to put forward valuable comments.

氟橡胶热缩管的性能分析及气泡原因

性能：

氟橡胶热缩管具有极好的耐高、低温性能、耐酸碱、耐油性是耐油橡胶中最好的，抗辐射、耐高真空性能好；电绝缘性、机械性能、耐化学腐蚀性、耐臭氧、耐大气老化性均优良。耐油及耐化学试剂性能，尤其适用于需要耐热的地方（如飞机或汽车引擎或油箱附近电气和液压系统）及需要耐化学溶剂的环境，缺点是加工性差，价格昂贵耐寒性差，弹性透气性较低。使用温度范围热缩管：－20℃～＋200℃。

用途：

主要用于国防工业制造飞机、火箭上的耐真空、耐高温、耐化学腐蚀的密封材料、胶管或其他零件及汽车工。在这些环境中线缆线束的绝缘保护和应力解除，保护电子电器设备免受损伤。

热缩管收缩后起泡：很多时候收缩后发现热缩套管部分地方起泡。主要产生的原因有：

1、没有按照操作说明书的要求从一端向另一端收缩或者双壁热缩管从中间开始向两边收缩，这样的方法有助于排除空气。

2、没有对被套物进行预热，直接将套管套上后收缩。

3、热缩管本身的原因，辐射剂量过低，材料分解。

以上一些问题是我们常见的问题，解决方法也提供参考。欢迎广大客户来提出宝贵意见。
