产品说明
Daikin PTFE (polytetrafluoroethylene) molding powders are excellent, fine cut resins, well suited for a
variety of demanding chemical, mechanical, electrical and non-stick surface applications. These
PTFE resins are fully fluorinated and have the best thermal, electrical, and chemical properties of all
fluoropolymers with a continuous service rating of 500°F (260°C). Daikin PTFE molding powders are
available in homopolymer and modified fine cut grades.
Daikin PTFE molding powders can be used continuously at temperatures up to 260°C (500°F) and
for short periods of time at higher temperatures. They also possess excellent low temperature
strength.
Daikin PTFE molding powders are completely inert to attack by all chemicals except
hightemperature, high-pressure elemental fluorine gas, molten alkaline metals and chlorine trifluoride.
The non-polar molecular structure makes Daikin PTFE molding powders ideal for use as
high-frequency insulating material. The dielectric constant and dissipation factor are uniformly low
over a wide frequency range.
Under ordinary conditions of use, Daikin PTFE molding powders possess the lowest coefficient of
friction of any solid material. Also, the non-stick properties of these products prevent most materials
from adhering to them.
Chemical/Mechanical—Packings, gaskets, diaphragms, bellows, corrosion-resistant linings, piping
components, pump parts, O-rings, V-rings, bushings, slide bearings, etc.
Electrical/Other—Insulating skived tape, insulating sleeves, terminals, connectors, sockets, spacers,
electronic parts, laboratory equipment, etc.
