Why can PET self-wrapped braided sleeve become a better material?

First of all, let's take a look at its effect and composition. The chemical formula of polyethylene terephthalate is -OCH2-CH2OCOC6H4CO-, commonly known as PET, which is a high polymer, which is dehydrated and condensed by polyethylene terephthalate. reflected. Ethylene terephthalate is obtained from the esterification reaction of terephthalic acid and ethylene glycol. PET is a milky white or light yellow, relatively highly crystalline polymer with a smooth and glossy surface. It has good physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120°C. It has excellent electrical insulation performance. Even at high temperature and high frequency, its electrical performance is still good, but its discharge resistance is weak. Stress relaxation resistance, fatigue resistance, friction coefficient, and specification reliability are all very good.

①It has excellent structural mechanical properties, and its impact strength is 3 to 5 times that of other plastic films, and it has good folding resistance.
②Acid and alkali resistance, fat resistance, dilute acid, dilute alkali resistance, and most organic solvents.
③ It has good high temperature and ultra-low temperature resistance, and can be used for a long time in the temperature range of 120 ° C. It can withstand high temperature of 150 ° C and ultra-low temperature of -70 ° C in short-term application, and the performance of mechanical equipment is not greatly affected by high and low temperatures.
④ Low gas and water vapor coverage, that is, good gas, water, oil and odor barrier properties.
⑤ High definition, can block ultraviolet light, good gloss.
⑥ Odorless and hygienic, it can be used as food packaging material at the same time.
PET self-wrapping Braided Sleeve is made of wire drawing with a diameter of 0.25MM or 0.20MM. It has good elasticity, flame retardancy and fire resistance. The surface of the product is smooth, soft and can be bent at will.
PET self-wrapping braided sleeve resists chemical corrosion and abrasion. Excellent elasticity, elasticity and other characteristics. The colors are gorgeous and all shapes and colors.
The price of PET self-wrapping braided sleeve is much lower than that of polyester braided network pipe, but the performance is not very different. As long as the requirements are not very high, the gap can be ignored.
