**The typical deflection range is approximately 5-40%
***Laminated polyester film provides low abrasion on one side as well as improved dielectric isolation.
• “A” version offers high strength
acrylic PSA for permanent
attachment
• UL recognized V-0 flammability
• RoHS compliant
All products are available on
aluminum foil “A’ or on “clean
break” glass “G” fiber carrier. As
with all previous Chomerics gap-
fillers, the “A” versions have a high
strength acrylic pressure sensitive
adhesive (PSA) for permanent
attachment to the cold surfaces.

HANDLING INFORMATION
These products are dened by
Chomerics as “articles” according to
the following generally recognized
regulatory denition for articles:
An article is a manufactured item
“formed to a specic shape or design
during manufacturing,” which has
“end use functions” dependent upon
its size and shape during end use and
which has generally “no change of
chemical composition during its end
use.”
In addition:
• There is no known or anticipated
exposure to hazardous materials/
substances during routine and
anticipated use of the product.
• The product’s shape, surface, and
design is more relevant than its
chemical composition.
These materials are not deemed by
Chomerics to require an MSDS. For
further questions, please contact
Chomerics at 781-935-4850.
