Products / Modifications
TECAST T (PA 6 C)
Basic type, tough-hard,
very good machining properties
TECAGLIDE green
(PA 6 C, solid lubricant)
Cast PA 6, sliding properties
modified for very low friction
TECAST L (PA 6 C, oil)
Sliding properties modified
TECAST L black (PA 6 C, oil)
Sliding properties modified,
black, also for outdoor exposure
to weather
TECAST L yellow (PA 6 C, oil)
Sliding properties modified, yellow
TECAST TM (PA 6 C, MoS 2 )
With MoS 2 , improved abrasion
resistance, suitable for outdoor
exposure to UV
TECARIM 1500 yellow
(PA 6 C, elastomer)
Signal colour yellow,
high toughness, good low
temperature impact strength
Application examples
Pulleys and guide rollers, chain guides, slide rails. The adjustable
toughness properties of TECAST T are used in
damping plates for impact and vibration hammers applied
for pile driving; large-scale gears used for the transfer of
motion rather than power transmission.
Due to its high toughness, TECARIM is also used at low
temperatures for winter technology applications (chain supports,
chain buffers for bulldozers); Stress relief blocks for
punching, deep drawing in automotive production, white
goods, tool building
Summary
Due to its relatively high but reversible moisture absorption,
PA 6 has a high level of toughness, whereby TECAST
T demonstrates even higher crystallinity and better machinability
than PA 6.
TECAST L and TECAGLIDE are special types with modified
sliding properties for improved sliding friction properties
and reduced abrasion.
Several TECARIM types can be varied over wide ranges (in
terms of strength, creep strength and toughness from
tough elastic to hard).
