Polymer material performance analysis

      The term "polymer material" refers to a polymer compound-based material, which is composed of a compound having a relatively high molecular weight, including rubber, plastic, fiber, paint, adhesive, and polymer-based composite material. Molecules are the form of life. Therefore, compared with other materials, the physical properties and chemical properties of the polymer material are relatively good, specifically the following four properties.

      1, insulation
      Polymer molecules are good insulators with insulating properties comparable to ceramics. It also has good insulation properties for heat and sound.
      2, heat resistance
      Thermoset plastics have higher heat resistance than thermoplastics. Commonly used thermoplastics such as polyethylene, polyvinyl chloride, nylon, etc., long-term use temperature is generally below 100 ° C; thermosetting plastics such as phenolic plastics are 130 ° C ~ 150 ° C; high temperature plastics such as silicone plastics, etc., can be 200 ° C ~ Use at 300 °C.
      3, corrosion resistance
     The polymer has a high chemical stability. They are resistant to water and inorganic agents, acid and alkali corrosion. In particular, PTFE, which is known as the plastic king, is not only resistant to strong corrosive agents such as strong acids and alkalis, but also stable in boiling aqua regia. Good corrosion resistance is one of the advantages of plastics.
      4, aging
      Aging refers to the process in which the polymer is degraded over time due to various factors during the long-term use and storage process, and the use value is gradually lost. Its main performance: rubber becomes brittle, cracked or soft, sticky; plastic is discolored, tarnished and cracked. These phenomena are irreversible and aging is a major drawback of polymers.https://www.supplyforever.com/
