Temperature has an impact on plastic seals. The following details the impact of temperature on the use of plastic seals in common places.
1. The plastic seal is hygroscopic. Do not open the package before use. After opening the package in a wet environment, try to use it up within 12 hours, or repack the unused plastic seal to avoid affecting the plastic seal during handling Tensile strength and rigidity.
2. When operating, use the tightening tension, which cannot exceed the tensile strength (tensile force) of the plastic seal itself.
3. The circle diameter of the bundled object should be smaller than the circle diameter of the plastic seal, and the remaining length of the belt after tightening is preferably 80MM. Plastic seals can maintain excellent mechanical properties and thermal aging resistance in a wide temperature range (-40 ~ 120 ° C)
4. The effect of humidity on plastic seals: Plastic seals can maintain excellent mechanical properties in a humid environment. Plastic seals have hygroscopicity, increased humidity (water content), higher elongation and impact strength, but tensile strength. And rigidity gradually decreases.
5, electrical characteristics and flame retardancy: plastic seals have good insulation, electrical rated temperature of less than 105 degrees does not affect its performance, flame retardancy reaches UL determination 94V-2 level.
Plastic seals are also called self-locking plastic seals, weather-resistant plastic seals, and the like. Due to the particularity of the plastic seal, its mold, injection molding process and materials are more particular. Plastic seals, which are straps that bind things, can be tightened more and more, and there are also detachable straps (live buckles). It is widely used in electronics factories, bundling televisions, computers and other internal connection lines, fixing of internal circuits such as lighting, motors, electronic toys, fixing of oil pipelines of machinery and equipment, packaging or bundling other objects, and can also be used in agriculture, handicrafts, etc. Bundle items. The plastic seal seals the filled bag through a one-way self-locking method, which acts as a seal.
