High-Density Silicone Gel
RADFLEX, a patented product, is a high-density resilient fire sealant material, developed and manufactured exclusively by PCI-Promatec. Installed as a liquid, by hand or machine, a complete fill in and around penetrating elements is assured. This material provides gamma shielding and fire resistance, yet allows significant penetrant movement both axially and laterally without loss of sealing capability. RADFLEX is protected under U.S. Patent No. 4,436,868.

Radiation Resistance
RADFLEX has been subjected to radiation exposure levels (1.13 x 108 Rads Gamma). Further details can be found below.

Fire Qualification
A mechanical penetration seal (at a minimum 147 lb/ft³) was exposed to 1.13 x 108 Rads Gamma, subjected to cycle movement testing, and then successfully subjected to fire testing. It is recommended a flexible silicone fabric boot be installed as an integral part of this design, providing mechanical securement. This patented product has received major insurance company and regulatory body acceptance.
Typically, RADFLEX is supplied at a nominal density of 150 lb/ft³. Higher density ranges can be achieved by formula variations when requested.

Reparability
RADFLEX can be easily removed. When additions or deletions of elements are necessary new RADFLEX material can then be applied to previously cured material to become an integral matrix with the already installed RADFLEX.

Packaging
RADFLEX is supplied in 150 lb. sets, (consisting of two six-gallon containers) or 75 lb. sets, (consisting of one six-gallon container) yielding approximately 1 or ½ cubic foot of cured material respectively.

Cure Time
Cure time for the RADFLEX is approximately 18 to 24 hours.
