Portable PP Boards With High Resistance Heat
PP board is a plastic panel primarily made from polypropylene. Our PP boards are lightweight yet durable, with high resistance to corrosion, acid and alkali, as well as moisture and mold-proof properties. They also offer excellent insulation, making them suitable for the electronics and electrical industries. PP boards are easy to process, supporting welding, cutting, and thermoforming, with a wide temperature resistance range (-10°C to 120°C).

PP sheets have certain characteristics in terms of high-temperature resistance. Their conventional operating temperature range is -20℃ to 80℃. Within this range, the physical and chemical properties of the sheets can remain stable without obvious deformation, cracking or performance degradation. PP sheets that have undergone special modification treatment have further improved high-temperature resistance. Some products can be used temporarily in environments of 100℃ to 120℃, or work stably for a long time at a temperature of around 90℃.​

In terms of performance, in conventional scenarios from room temperature to 80℃, PP sheets can withstand the long-term effect of media such as hot water and hot gas. For example, in applications such as the outer protection of household or industrial hot water transmission pipelines and the inner lining of hot water storage tanks, there will be no structural damage due to temperature effects. For modified PP sheets, in some scenarios with slightly higher temperatures, such as trays used for temporarily holding hot food materials at 80℃ to 100℃ in food processing, or equipment linings in industrial production that come into contact with medium-temperature liquids, they can also maintain good stability and are not prone to softening or deformation.​

In terms of applications, conventional PP sheets can be used to make hot water tank baffles in kitchens and other household scenarios, as well as protection for components that do not come into contact with high temperatures in ordinary industrial equipment. Modified PP sheets are suitable for lining of hot material conveying tracks in food processing plants, medicine turnover boxes in medium-temperature environments in the pharmaceutical industry, and some parts in automobile engine compartments that do not directly contact high-temperature sources, etc.

However, the high-temperature resistance of PP sheets still has limitations. If they are in a high-temperature environment above 120℃ for a long time, their performance may decline. Therefore, they should be selected reasonably according to specific temperature requirements.​
