There are various high-temperature environments in our daily lives or industrial production, with temperatures of one to two hundred degrees Celsius being a common occurrence. The corresponding requirements for heat shrink tubing are also more stringent, and ordinary heat shrink tubing or plastic tubing is obviously unable to meet them. Various types of high-temperature resistant heat shrink tubes have emerged as the times require. Solved the problems encountered by many industries due to the lack of suitable products in high-temperature environments.
High temperature resistant heat shrink tubing, as the name suggests, is a heat shrink tubing with a higher temperature resistance level. Usually, the temperature resistance level of our common heat shrink tubing is between 85 ℃ and 135 ℃. In the heat shrink industry, heat shrink tubing with a temperature resistance greater than or equal to 135 ℃ is collectively referred to as high-temperature heat shrink tubing. High temperature heat shrink tubing can be divided into: 150 ℃ heat shrink tubing (which is divided into products made of polyolefin material and PVDF material) according to temperature level and usage environment; The main material of oil resistant heat shrink tubing is made of radiation elastomer; The main material of the 175 ℃ heat shrink tube is PVDF; 200 ℃ heat shrink tubing mainly consists of sleeves made of silicone rubber and fluororubber; 260 ℃ heat shrink tubing is currently the highest temperature resistant grade in the heat shrink industry, with Teflon heat shrink tubing ranking first in terms of temperature resistance.
The temperature referred to by high-temperature resistant heat shrink tubing refers to the long-term working temperature of the heat shrink tubing, rather than the temperature it can withstand for a short period of time. If it is only a temporary requirement for high temperature resistance, ordinary 125 ℃ heat shrink tubing can meet the requirements. In performance testing, ordinary heat shrink tubing can withstand temperatures for up to 168 hours in a working environment of 175 ℃. So some customers just need to reach high temperature in a short period of time and do not need to choose high-temperature resistant products. Ordinary heat shrink tubing can meet the requirements. High temperature heat shrink tubing has advantages such as high temperature resistance, excellent mechanical properties, and good chemical resistance. High temperature heat shrink tubing can be applied to various high-temperature environments such as cable insulation protection, insulation treatment or stress relief at the ends or connections, coating and insulation protection for cable processing, solder joint protection, electronic component coating, aerospace, automotive, high-temperature motors, high-temperature sensors, household appliances, etc.
