These applications all use the low friction coefficient and non-stick characteristics of the PTFE material, which shows that the tension of the product is reduced to the lowest when the product passes, and the attached dirt is also easy to clean. In addition, if the PTFE material is applied to rollers PTFE coated adhesive tapes or inlays on other parts, used as guide wheels, PTFE rollers, it can allow films, paper, textiles, etc.
Molding and secondary processing are difficult and other shortcomings, so that its application is limited. Compared with other polymers, polytetrafluoroethylene PTFE has its unique advantages, but it also has some defects, such as poor machining performance, large linear expansion coefficient, poor creep resistance, easy cold flow, and poor wear resistance.
Teflon PTFE material has the smallest surface tension and inertness among solid materials, and does not adhere to any substances are installed on the loom to prevent the adhesion of various threads and make PTFE special-shaped parts for mechanical equipment to prevent glue and other adhesions from being difficult to remove; and the varnished cloth composited with PTFE coating and glass undergoes heat shrinkage.
For example, the suspension micropowder M111 from Daikin Japan and DF16 from Dongyue are all varieties with better cleanliness and wear resistance. PTFE tetrafluoroethylene material has the lowest coefficient of friction, excellent self-lubrication, and excellent resistance to high and low temperatures, which makes it widely used in anti-sticking applications such as manufacturing non-stick pans. to pass quickly; it can also be made into thin sheets such as chemical fiber molded sheets, textiles Lubricating blocks, etc. PTFE manufacturers are also constantly improving and applying.
At present, the focus of domestic and foreign research on PTFE is to find appropriate methods to modify it, improve its performance to a certain extent, and expand its application range. Covering on the substrate, etc. To strengthen the application research and development of PTFE, we need to focus on modification technology research and development of new high-performance PTFE composite materials.
