MT1000
Altera medical-grade, thin wall, semirigid,
fluoropolymer heat-shrinkable tubing
Altera MT1000 heat-shrinkable tubing is
tough, semirigid tubing with a very thin
wall construction. It is especially suitable
for applications requiring high-
temperature performance, outstanding
resistance to abrasion and cut-through,
and excellent resistance to a variety of
fluids. In polar media, such as aqueous
systems and alcohols, property retention
and dimensional stability are exceptional.
The translucent polyvinylidene fluoride
material permits visual inspection of

covered components. Altera MT1000
tubing provides electrical insulation
and strain relief for components that
are exposed to high temperatures –
either during operation or during
sterilization. With its thin-wall
construction, Altera MT1000 tubing
is ideal for applications that have
clearance constraints.
Altera MT1000A tubing provides an inner
layer of adhesive. During installation, the
USP Class VI adhesive layer will reflow
around the substrate to provide sealing
or blocking against fluids and other
bioburden materials.
Altera MT1000 tubing may be sterilized
by radiation, ethylene oxide, steam, and
dry heat with no significant change in
properties. It is fabricated from materials
that meet the requirements of U.S.
Pharmacopeia (USP) Class VI plastics
(contact with injectables and body fluids
or tissue).
MT1000A: -55°C to 125°C
Recommended maximum temperature for use as a primary insulator: 135°C
