The Chemours Company
產(chǎn)品說明:
Teflon ™ PFA 9738-JN is a premium resin available only as a free-flowing powder. Its most unique features, controlled particle size and size distribution, provide proper flow and fusion behavior in rotational molding process. In addition, Teflon ™ PFA 9738-JN is chemically modified to yield enhanced resin purity, lower extractable fluorides, and freedom from other foreign materials. Its surface smoothness is improved by minimizing spherulite size, and its chemical permeability resistance is enhanced by increasing its crystallinity. This product contains no additives and is designed for hostile chemical environments where purity in the parts-per-billion range is needed.
The properties of Teflon ™ PFA 9738-JN in molded form are similar to other grades of Teflon ™ PFA (perfluoroalkoxy) fluoroplastic resin. Many properties are similar to those of polytetrafluoroethylene (PTFE).
Rotational molding is a favored process for making large, hollow parts or for lining objects with complex inside surfaces. Applications for Teflon ™ PFA 9738-JN include linings molded in place using the object to be lined as the mold. Teflon ™ PFA 9738-JN is preferred when high performance is a major requirement involving chemical, thermal, and mechanical stress.
Properly processed rotational moldings made from neat Teflon ™ PFA 9738-JN resin provide the superior properties typical of the fluoroplastic resins: retention of physical properties after service at 260 °C (500 °F), useful properties at –196 °C (–321 °F), and chemical inertness to nearly all industrial chemicals and solvents. Dielectric properties are excellent. Molded products have moderate stiffness and high ultimate elongation.
Table 1 shows the typical property data for Teflon ™ PFA 9738-JN.
In a flame situation, products of Teflon ™ PFA 9738-JN resist ignition and do not themselves promote flame spread. When ignited by flame from other sources, their contribution of heat is very small and added at a slow rate with very little smoke.
Typical End Products
Teflon ™ PFA 9738-JN is ideal for many end products for fluid handling in the chemical processing industries, including pump housings, vessels, columns, elbows, tees, and pipe sections with unusual shapes. In addition, any hollow structure with internal contours that permit uniform coating by powder flow is a candidate for lining, provided it can withstand high temperatures. Because of its enhanced resin purity, Teflon ™ PFA 9738-JN is suitable for use in semiconductor manufacture and fluid handling systems for industry or life sciences.
