Thermal shrinkage casing material, that is, thermal shrinkage material, also known as polymer memory material, is a combination of polymer materials and radiation processing technology materials, is an intelligent material. The polymer materials commonly used in life have the structure of polyethylene (PE), polyvinyl chloride (PVC) and other common linear materials, after the radiation of radioactive sources such as electronic accelerators into a mesh structure, these materials will have a unique memory function, after expansion, cooling to set the line, After heating, you can regain it to its original shape.

Thermal shrinkage Casing material has memory function can be used to make hot shrinkage pipe, membrane material, special-shaped materials, the main feature is through heating shrinkage after coating on the surface of the object, can play the role of insulation, moisture-proof, sealing, protection, continuity and so on, effectively protect the package products, will not let the product rust, moisture and other phenomena.

Thermal shrinkage Casing material is a new type of high-tech materials, its manufacturing principle is the use of rubber stretching after the heat shrinkable pipe heating will automatically restore the characteristics, is the production of rubber pipe components, its expansion of the part of the support, when applied directly to the support, rubber pipe will be directly contracted on the coated object. This does not require heating for the heating shrinkage process of the heat shrinkable casing, so it is called the cold shrinkage casing.

Like the heat shrinkable casing, the cold shrinkage casing is widely used in our life such as power cable connectors, communication cable connectors, electrical and electronic insulation, military space system node protection, all kinds of wire harness joint protection, such as the need for insulation, sealing and anti-corrosion applications.

The above is the characteristics of heat shrinkable casing, these characteristics require to meet people's needs.

Heat shrinkable pipe is often used in electronic products, heat shrinkable tube color is also a lot, we often have black, there are red, yellow and other different colors, for a variety of colors, electronic products on the need for double-walled heat shrinkable casing is not the same, different colors are to be used in different electronic products. But often the customer does not like this color, is the manufacturer in the production time has a kind of contradictory psychology.

Among the customers of some manufacturers, there are a large number of customers are not aware of the heat shrinkable pipe, only know that the manufacturer will be in accordance with his requirements to produce the required goods, but sometimes manufacturers are really bitter can not say, in order to communicate in the process will not appear unpleasant scenes, we need to understand the difficulties of manufacturers.

Color Masterbatch is the main component that determines the color of hot shrinkage, after the heat shrinkable tube has been treated several times, the color is changed.

In the extrusion process, affected by the high temperature, the masterbatch will occur some performance changes, impurities will be squeezed out along.

In the process of irradiation, electronic rays will be the expansion of thermoplastic tubes, and the emergence of cross-linked reactions, these are physical high temperature heat shrinkable tube changes, the color has a certain impact.

In the process of expansion of the heat shrinkable tube, the general use of glycerin heating, this time high temperature, impurities and some factors can affect the color changes.

Some of these disturbances are basically inevitable, the current heat shrinkable pipe processing technology can be difficult to control, so customers need to understand the heat shrinkable pipe processing manufacturers, can only ensure that you need the color of the error is very small, can not say that there is no error.

There is also the most important, there is no heat shrinkable pipe manufacturers can be all the colors can be aligned, different specifications of the product, the color of the demand is very large, the common several colors are there, so the general manufacturers are fixed several colors and heat shrinkable tubes. And each produced by the heat shrinkable tube color is not possible the same, the same manufacturer produced color are colored poor, not to mention is different manufacturers, unless it is the same batch of products, it is possible to achieve color consistency.

热缩套管的作用与影响其颜色的因素

热缩套管材料即热缩材料也被称为高分子记忆材料，是高分子材料与辐射加工技术材料结合的产物，是一种智能性材料。在生活中普遍使用的高分子材料有聚乙烯(PE)、聚氯乙烯(PVC)等常用的线性材料的结构，经过电子加速器等放射源的辐射以后变成网状结构以后，这些材料会具备独特的记忆功能，经过扩张、冷却定行以后，受热以后又可以重新恢复到原来的形状。

热缩套管材料具有记忆功能可以用于制作热缩管材、膜材、异形材，主要的特征就是通过加热收缩以后包覆在物体的表面，能够起到绝缘、防潮、密封、保护、接续等作用，有效保护包裹产品，不会让产品出现锈蚀、潮湿等现象。

热缩套管材料是一种新型的高科技材料，其制造的原理就是利用橡胶拉伸以后热缩管受热会自动复原的特性，现制作好橡胶管的部件，将其扩张的部分嵌入支撑物，应用的时候直接将支撑物抽出，橡胶管就会直接收缩在被包覆的物体上。这对于热缩套管加热收缩过程，是不需要加热的，因此被称为冷缩套管。

同热缩套管一样，冷缩套管也广泛的运用在我们的生活中比如电力电缆接头、通讯电缆接头、电子电器绝缘、军工航天系统的节点防护、各类线束接头保护等需要绝缘、密封以及防腐的应用场合。

以上就是热缩套管的特性，这些特性要求满足人们的需求。

热缩管是经常使用在电子产品上的，热缩管的颜色也是很多的，我们常见的就有黑色，还有红色，黄色等等不同的颜色，针对各种颜色，电子产品对双壁热缩套管的需要是不一样的，不同的颜色是要使用在不同的电子产品上的。但是往往是顾客不喜欢这种颜色，是厂家在生产的时候有一种矛盾的心理。

在一些厂家的顾客之中，有绝大数的顾客是对热缩管是没有了解的，只知道厂家会按照他的要求去生产需要的商品，但是有时候厂家是真的有苦说不出，为了在交流过程中不会出现不愉快的场面，我们就有必要了解一下生产厂家的苦衷。

色母粒是决定热缩光颜色的主要成分，在热缩管经过过多次的处理工艺之后，在颜色上是有所变化的。

在挤出的过程中，受到高温的影响，色母粒会发生一些性能的变化，杂质也会跟着被挤出来。

在辐照的过程中，电子射线是会是热塑管发生扩张，并有交联反应的出现，这些都是属于物理性的高温热缩管变化，对颜色有一定的影响。

在热缩管的扩张过程中，一般使用的都是甘油加热，这时候高温，杂质和一些因素都是能影响到颜色的变化的。

这些干扰有些基本上是不可避免的，现在的热缩管的加工技术是能难得到控制的，所以顾客需要明白热缩管的加工厂家，只能保证和你需要颜色的误差很小，不能说没有一点误差的。

还有最重要的，没有那一家热缩管的厂家能够把所有的颜色都能配齐的，不同的规格的产品，颜色的需求是很大的，常见的几种颜色都是在那的，所以一般厂家都是有固定的几种颜色和热缩管。而且每家生产出来的热缩管颜色都是不可能一样的，同一家厂家成产的颜色都是有色差的，何况是不同的厂家，除非是同一批的产品，才有可能达到颜色上的一致性。
