Temperature resistance of flame retardant tubes
Today we talk about the topic of temperature resistance of flame retardant tubes. Flame retardant tubes can also be called flame retardant heat shrinkable tubes.
There are differences between the flame retardant tube and the ordinary heat shrinkable tube. Let's briefly introduce the difference between the two. The flame retardant tube and the ordinary heat-shrinkable tube are made of PE, EVA and other materials through special production process, and have the characteristics of heating to shrink and tightly wrapped on the quilt. However, ordinary heat-shrinkable tubes can only be insulated, protected, anti-corrosive, and leak-proof. They are not flame retardant. If the customer's product requirements require flame retardant, then the flame retardant tube must be purchased to meet the purchase conditions.
The flame retardant tube contains a flame retardant, which can prevent combustion within a certain time range when encountered. In general, the higher the level of flame retardant, the better the effect, the majority of customers can choose the level of the flame retardant tube according to their own needs.
Next, let’s simply talk about temperature resistance of flame retardant tubes. The temperature resistance of flame retardant tubes is divided into temperature resistance at the time of shrinkage and temperature resistance at a normal temperature after shrinking the flame-retardant tube. Under normal circumstances, the flame-retardant tube should not be used for a long time in an environment with excessive temperature. If the temperature is too high for a long time, cracking and melting will occur. Using it in an environment where the temperature is too high for a short period of time also affects the life of its use, resulting in a reduced lifespan.
In fact, the temperature resistance of the flame retardant tube cannot be defined by one-sided data, which is usually related to the ambient temperature used. The temperature of the environment largely determines the life of the flame retardant tube.
