In the hot weather in summer, everyone is afraid of avoiding the heat. Although the article discusses cold-pressed sheet and heat insulation sheet, the two kinds of materials are not for people to use in summer, but for insulating materials. let us take a look at the differences in the performance of the two materials.
Material distinction: The material of the cold-pressed sheet is fiber paper and phenolic resin, also the phenolic resin is a very high temperature resistant material.
Usually cold-pressed sheet is also called phenolic sheet, which is different from phenolic sheet as insulation material.
Insulation sheet will also be called heat insulation sheet. The material is glass fiber material and composite material. The composite material here is high heat resistance. The heat insulation board is a kind of harmless material for human body. which is mainly asbestos. but this insulation board does not contain asbestos.
Distinction of performance use: cold-punching sheet is punched and cut at low temperature, good toughness, not easy to be brittle and stratified, it is not easy to bubble even under high-frequency voltage, mainly suitable for PCB drilling, reinforcement, radio, electrical equipment, etc. Insulated parts.
The heat insulation board is mainly used to separate the temperature and heat. It is mainly used in molds such as plastic molds and injection molds. Injection molds usually require high temperature materials and low temperature molds. Insulation methods must be used in the same machine.
Keeping the injection mold at a low temperature,does not make the temperature of the injection molding machine too high.
This requirement can be met by installing an insulating insulation panel between the injection molding and the injection molding machine. The main properties of the insulation sheet are high mechanical and dielectric properties, good heat resistance and moisture resistance, and good processability.
In summary, there is no similarity between the specific performance of the cold-pressed sheet and the heat-insulating sheet, and there is no similarity in the application fields. The most obvious common point is that they are all insulating materials and have insulation properties.
