Dear Colleagues,
I am looking for an alternative to Tygon tubing.    I have used this
tubing to pad wire mounts for artifacts for quite some time.  Its
properties of flexibility, "cushiness" and grip make it ideal for this
purpose.  However, I have come to find out that it is composed of PVC,
which is a material to be avoided from a preventive conservation
standpoint.  Polyethylene and polypropylene tubing exists but it is much
too rigid for this purpose.  Cole-Parmer has suggested vinyl or silicone
tubing as an alternative.  Does anyone know if these are safe
alternatives?  I thought vinyl was PVC (poly-vinyl chloride).  Are there
safe vinyls?  Thanks in advance for any information you might have.
Sincerely,
David Ryan
