Techtron HPV & PEEK HPV
Specifications
TECHTRON HPV & PEEK HPV GRADES
Techtron ® PPS (Unfilled)
Techtron ® PPS offers the broadest resistance to
chemicals of any advanced engineering plastic. They have no known solvents
below 392°F (200°C) and are inert to steam, strong bases, fuels and acids.
Minimal moisture absorption and a very low coefficient of linear thermal
expansion, combined with stress-relieving manufacturing, make PPS ideally
suited for precise tolerance machined components. Techtron ®
is
Natural
(ivory or off-white) in color and is FDA and Canada
AG compliant.
Techtron ® HPV (Bearing Grade)
This grade of Techtron, containing carbon graphite and PTFE lubricants,
offers the lowest coefficient of friction and the best machinability for all
PPS grades. Techtron ® HPV has an excellent
combination of low friction, low wear, high limiting PV, low mating part
wear, and easy machining. Techtron HPV is
medium blue
in color.
PEEK (Unfilled)
This general purpose grade is unreinforced and offers the highest elongation
and toughness of all PEEK grades. This material is standard in
Natural (a
very light brown or tan) color, but is also
available in
black
. Black PEEK is ideal for instrument components where
aesthetics are important, as well as for seal components where ductility and
inertness are important. The unfilled PEEK grade complies with FDA
regulation 21 CFR 177.2415 for repeated food contact. Unfilled PEEK is also
USDA and Canada AG compliant.
Ketron ® HPV (Bearing Grade)
This grade of PEEK, containing carbon fiber reinforced with graphite and
PTFE lubricants, offers the lowest coefficient of friction and the best
machinability for all PEEK grades. Ketron HPV has an excellent combination
of low friction, low wear, high limiting PV, low mating part wear, and easy
machining. Ketron HPV is
black
or
dark grey in color.
