General Info

INSULATION SEALING & CAULKING CORDS
Nu-Calgon Insulation Sealing Cords are nonstaining sealers formulated from the highest quality raw materials. They
are water-resistant, dust-resistant and white in color, non-staining and non-hardening with excellent adhesion to most
surfaces and an excellent insulation value. (3/8˝ x 25´)
Part Number: 4216-27
THUMB-TITE
®
Thumb-Tite is formulated and manufactured for use in many sealing, insulating and general maintenance
applications. It has excellent adhesion capability and is non-staining, non-hardening and unaffected by wide
variations in temperature and is an excellent thumbing grade. Thumb-Tite remains flexible at -20ºF and is non-
sagging up to 350ºF. It is packaged in 2 lb. boxes, each box containing two one-pound bars.
Part Number: 4216-92 - 2 lb. box
NU-FOAM
®
Nu-Foam is an expanding, polyurethane, prepolymer foam that is used as a sealant and an insulating product. It is
designed to seal, fill and insulate small cracks, gaps and voids, and is suitable for many HVAC applications. Nu-Foam
expands into cracks and is tack-free in 30 minutes and completely dry in about 4 hours. This product is fire retardant,
UL listed and has an R-Value of 4.9 per inch thick.
Part Number: 4293-04 - 9 ounce can
Part Number: 4293-75 - 20 ounce can
Tensile PSI: 1/16˝ thick sample is compressed between two aluminum discs in a 2 inch square area. Sample held
under compression for 15 minutes. Tested at 2˝ per minute.
Hardening: Condition sample for penetrometer in a 158ºF oven for one week. Condition sample in 75ºF water bath
for one hour before determining 100 gram needle point penetration.
Sag: Place 1/8˝x 2˝x 2˝ piece of cork tape om aluminum plate. Condition at 75ºF for one hour. Place sample in 350ºF
oven. Measure flow or sag after 24 hours.
Thermal Conductivity: This is a direct measure of the insulation capability of the tape. The smaller the value, the
better the insulation provided.
