Tapering
Immerse a short loop of tubing, without tension, beneath the surface of sesame oil heated
to 200-2200C. When the heated segment is observed to "relax" (shorten and swell
slightly), remove from the oil and pull steadily. Hold extended a few seconds until tubing
cools.
This method may be used to produce extremely fine terminal segments. The rate of taper
depends on both oil temperature and pulling rate.
End Shaping
To form flares or end beads, dip tubing end into hot oil. After relaxation occurs,
withdraw and form with a mandrel or surgical instrument.
Bonding and Cuff Aattachment
Cuffs for the 040 size Micro-Renathane may be cut from 080 Micro-Renathane and attached
with silicone adhesive of the "bathtub seal" variety.
Sterilizing
Micro-Renathane may be gas sterilized. Compatibility with chemical sterilants should be
evaluated before use.
Stability
Since no ultraviolet stabilizer has been added, Micro-Renathane may yellow slightly with
age. Although this has no effect on its properties, you may wish to protect unused tubing
from light.
