How To Use Teflon

Business PTFE ( teflon ) Rod is a remarkable product. PTFE Polytetrafluoroethylene was discovered on April 6, 1938 by Dr. Roy Plunkett at the DuPont research laboratories. And this original PTFE was further developed by Dupont, and was called Teflon and released as a product in 1945. This product is extremely chemical resistant, and can handle temperatures above 500 degrees. One of the first household uses for PTFE is the Teflon Coated Frying Pan. While this pan works very well, it is a different process than the PTFE Teflon Rod and Sheet we supply. It is a sprayed on coating that is almost black in color, where the pure PTFE Teflon Rod and Sheet is bright white in PTFE – Teflon Round Rod Steam Valve Packingcolor. What are some of the uses for PTFE Teflon Rod? Because PTFE exhibits high temperature and chemical resistance, it is .monly used in valve applications. From simple steam / hot water valves to high heat, caustic chemical valves in the fluid handling industries. This material is a semi-rigid to rigid plastic, and can be machined very easily one of the easiest plastics to work with. The PTFE Teflon rod can be machined to very close tolerance, and in most small diameter rod it is supplied with on the diameter (check for tolerance on your requested size). The chemical resistance is one of the key properties associated with the material. In sheet or thin sheet (film) PTFE Teflon is used as gasket material for similar high heat and chemical resistant flange and seals. Since 1945 Dupont has been the world leader in producing PTFE resins as their brand, Teflon. Over the last couple of years, with the global shortage of Fluorspar (a key ingredient in producing all Fluoropolymer Plastics) Dupont has made some changes to their product offerings. Included in this change is a discontinuation of the production of Teflon 9B the most .mon granular molding powder (resin) used in the production of Teflon Rod and Sheet. This has the industry in a panic, the remaining global suppliers of PTFE resin are scrabbling to fill the void left by this decision. What does this mean to you? If you are used to purchasing Teflon brand rod or sheet, you may find the base materials will not be from Dupont. Our suppliers have small amounts of the Dupont resin, but mostly are replacing their raw materials with molding powder from other manufacturers. It may be, in the very near future, that all Ptfe rod and PTFE sheet may not be made from Teflon brand resin. About the Author: 相关的主题文章:
