NOTE: Raw Material Change/Qualification in Process
Advanced Polymers (AP) recently learned that the manufacturer of its existing PET
resin is no longer able to supply the resin. A chemically identical replacement
PET resin has been selected and biocompatibility testing has been completed. Customer
notification has begun based on historical ordering data, however AP will notify
every customer who has purchased an item number within the last three years manufactured
from the existing PET resin at least one year before our supply runs out.
In regard to our heat shrink tubing, please note that we have begun the process
of creating standard/non-standard sizes using the new PET resin. When ordering heat
shrink tubing, please be aware that all heat shrink tubing item numbers that
begin with "103" are made with the replacement PET resin. All other
item numbers are made with the existing PET resin and will be obsolete once our
current supply runs out. AP cannot commit to how long any item number will
remain in stock under the existing PET resin. If the item number
you are interested in is not available in a "103" number and you are planning on
submitting the product for regulatory approvals, please contact AP and provide us
with your timing requirements and we will work to prioritize your order.
The online catalog allows our customers to search for Polyester Heat Shrink Tube item(s) based on a specific criteria.
The customer can enter a Max OD, select an available color, select the units, and/or number of items per page.
The filter criteria are shown on Table 1.

Upon selecting the search criteria and pressing the Search button a list consisting
of five or six columns is displayed as described on table 2.

Use the following steps to choose the correct tubing from our online catalog:
Note: In some cases it may not be possible to choose the smallest diameter
possible or even to use any of the tubes selected using the procedure described
above. This occurs for example, when the product to be covered has a varying or
tapered diameter or when the heat shrink tube must fit over a larger section of
product but is to be shrunk on a smaller section. When shrinkage of more than 15-20%
is required, we generally recommend drawing the tube down by applying axial tension
during the shrinkage. These methods will allow shrinkage of up to 70% or more.
