Notes
SILVAC offers the excellent temperature resistance of silicone
in a vacuum-rated hose (29.9 in./Hg at 70°F). The hose construction
allows strong vacuum at elevated temperatures; sample testing is recommended.
The construction consists of mandrel-wrapped layers of
polyester-reinforced silicone elastomer incorporated around a spiral wound
reinforcing wire. The wire construction makes SILVAC crush and kink resistant
yet quite flexible.
SILVAC, a peroxide-cured product, is made in accordance
with FDA Good Manufacturing Practices (GMP). Each length is individually
packaged in a heat-sealed polybag. Platinum curing (for reduced extractables)
is available through minimum order.
SILVAC may be low pressure steam sterilized in-line or
autoclaved up to 250°F in a normal autoclaving cycle. Its smooth bore
and the ability to not allow material to stick to the tube wall facilitates
easy cleaning and system purging. If exposed to repeated steam sterilization
or long-term high temperature or pressure, silicone will eventually relax
and become gummy. It should then tbe replaced.
Care is recommended in the selection and application of
fittings and clamps for SILVAC as sharp barbed fittings or unlined metal
clamps could tear into the wall and possibly cause a failure.
Limited samples of stock material are available upon request. |
