PTFE 7C X
Fluoroplastic Resin
Description:
PTFE 7C X is a white powder with a small particle size. The small particle size of PTFE 7C X helps to minimize voids, even at relatively low molding pressures. Its most unique feature is the irregular, fibrous character of the particles. The fibrous particles promote good capture and uniform distribution of inorganic fillers when they are added to modify the mechanical properties of moldings.
Typical Applications
Many end products are fabricated, which include skived film and sheet. It can be used for applications, such as:
• Gasket
• Bridge or pipeline bearing pads
• Piston rings
• Diaphragms
Many end products are made with filled compounds based on PTFE 7C X. The filled compounds provide a wide choice of modified mechanical properties.
Processing
PTFE 7C X is processed in two steps: preforming and sintering. The powder is first compacted into a preformed shape approximating that of the desired molding. A precise heating (sintering) and cooling cycle is then used to consolidate the molding at temperatures above the crystalline melting point of the neat powder. The properties of a finished molding are dependent on preform pressure, sintering time and temperature, and cooling rate.
PTFE 7C X is used to make relatively large objects in molds that can be filled manually. Small particle resins do not flow properly in automatic feeding systems.
