PTFE
Sheet and Film.....................ASTM D 3294 (and MIL-P22241). Describes the
properties and characteristics parameters for PTFE molded sheets (thicker than .250 inches).
PTFE
Rod.....................................ASTM 1710 (and MIL-P 19468). Describes the
properties and characteristics parameters for different grades of PTFE extruded and molded rod and for
heavy-walled tubing.
PTFE
Molded Sheet or Shapes.......ASTM D 3294. Describes the properties and characteristics
parameters for molded PTFE shapes and molded PTFE sheets.
PTFE
Skived Tape.........................ASTM D 3308. Describes the properties and
characteristics parameters for skived tape (.250 inches and thinner)
Filled Compounds made
With PTFE…………………………….ASTM D
4745. Describes the properties and characteristics parameters for filled molding compounds made with
PTFE. The specification provides
standards for bulk density, tensile strength and elongation of PTFE filled with different percentages of
glass fiber, glass fiber and Molybdenum Disulfide, graphite, carbon and graphite, bronze, bronze and
Molybdenum
Disulfide and stainless steel.
PTFE
Tubing………………………....ASTM D 1710. The
tubing is intended for electrical, mechanical, chemical and medical applications manufactured from
extrusion
resins made from PTFE resins.
Molding
and Machining Tolerances
for PTFE resin parts…...................ASTM 3297. This specification defines tolerances
applicable to parts molded and free sintered from PTFE resins and to machined parts produced from basic
shapes of compression molded
or ram extruded resins. The thermal expansion of PTFE parts between 64F and 70F is non-uniform due to a
critical transition zone characteristic of PTFE resins.
