Heat-resistant material (paper-plastic) is a kind of composite material made of paper pulp and plastic as the main raw materials, processed by special technology. It combines the environmental friendliness of pulp and the durability of plastic, and at the same time has a certain degree of high temperature resistance after technical improvement. This material can maintain structural stability and physical properties in high temperature environments and is suitable for a variety of scenarios that require heat-resistant performance. The main characteristics of heat-resistant materials are:

  1. Environmental friendliness:
    1. The main components of paper-plastic heat-resistant materials come from renewable resources (e.g., wastepaper, natural fibers), reducing dependence on petroleum-based materials.
    2. The material itself has good degradability or recycling value, which is in line with the concept of circular economy and friendly to the environment.
  2. High temperature resistance
    1. After modified treatment, the paper-plastic heat resistant material can maintain stable physical properties in the temperature range of 150℃ to 300℃.
    2. It has high heat distortion temperature and can resist softening and deformation caused by high temperature.
  3. Mechanical strength
    1. Paper-plastic composites have both the flexibility of paper and the rigidity of plastic, with good tensile strength, compressive strength and wear resistance.
    2. It can still maintain high mechanical strength under high temperature environment, which is suitable to be used in the application scenario of load bearing or protection function.
  4. Water and oil resistance
    1. Due to the addition of modified plastic components, the paper-plastic heat-resistant material has good waterproof and oilproof performance, suitable for use in wet or greasy environments.
  5. Excellent processing performance
    1. Paper-plastic heat-resistant material can be processed by injection molding, extrusion, hot pressing and other molding processes, with high production efficiency, and easy to design into different shapes and specifications.
  6. Lightweight
    1. Compared with traditional metal or ceramic heat-resistant materials, paper-plastic heat-resistant materials have lower density and are lighter in weight, which makes them easier to be transported and installed.
