MT2000
Altera medical-grade, very thin wall,
polyolefin heat-shrinkable tubing
Altera MT2000 heat-shrinkable
tubing is made of a tough, modified
polyolefin with a very thin wall
construction. It is especially suitable
for medical applications requiring
lubricity, flexibility, and excellent
electrical insulation performance.
Altera MT2000 offers a cost-
effective alternative to FEP while
maint ainin g performance after
gamma sterilization.
Altera MT2000 tubing can provide
electrical insulation, mechanical
protection, strain relief, color coding,
and identification for many medical
components and devices.
Altera MT2000A 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 MT2000 tubing may be
sterilized by gamma radiation or
ethylene oxide with no significant
changes 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).
