Engineering plastics with a temperature resistance of over 100°C
Thread Content
In the chemical manufacturing process, it is common to encounter materials that are highly corrosive and have temperatures above 100°C. High-alloy steel is too expensive to use, while polytetrafluoroethylene cannot be welded, making modifications during processing or after installation rather troublesome. Glass fiber reinforced plastic can withstand high temperatures, but due to its complex composition, there is a concern that some organic substances might escape during use, affecting the purity of the final product. Additionally, glass fiber reinforced plastic has poor workability for making alterations once it has been molded. Therefore, there is a need for engineering plastics with high heat resistance and a relatively reasonable price that are affordable, in order to solve practical engineering challenges. Discussion is welcome.
A temperature above 100°C represents a threshold for non-metallic materials; the choice of material depends on the specific conditions of the medium. Each type of material has its own advantages and disadvantages, and no material is suitable for all situations. Detailed parameters are required to make a decision.
I’m using this for a project I’m working on; it’s said to be able to withstand temperatures of over 120 degrees
With such high temperatures or severe corrosion, you can choose PVDF, which can withstand temperatures up to 140 degrees, is resistant to severe corrosion, and resistant to ultraviolet rays.
Hehe, polytetrafluoroethylene can be used, but it’s not cheap either.
Polyoxymethylene (POM) material can withstand temperatures above 100 degrees and exhibits stable performance; it is generally used in the manufacture of various pipes and valves. Its use as a lining material is not yet mature, but if any company can utilize this material for lining purposes, it will meet the requirements of engineering projects
What is relatively economically reasonable is to use PTFE materials
Glass fiber-reinforced polypropylene coffins can be used, with a temperature resistance of up to 120 degrees
Using FRPP pipes, the temperature resistance can reach 100 degrees, although the distance between pipe supports is shorter.
