Used in nuclear facilities around the world, our line of passive fire protection products includes proprietary penetration seal systems qualified under some of the most rigid industry standards for fire, flood, pressure, and radiation resistance.

PCI Promatec, whose roots go back to the beginning of the nuclear passive fire protection industry in the mid 70’s, was formed by the acquisition of Brand Fire Protection Services (formerly BISCO), B&B Promatec, Insulation Consultant & Management Service (ICMS), Techsil and Chemtrol, and has provided and continues to provide our products and services to the vast majority of American nuclear power facilities. As PCI Promatec, we continue to offer the original formulations of products once offered by Brand, Promatec, ICMS Techsil and Chemtrol.

Passive Fire Protection Products

Servicing Clients Worldwide

PCI Promatec has served the needs of the nuclear passive fire protection industry for more than forty years, and our products can be found in facilities around the world. Priding ourselves in delivering top-quality materials and reliable service, PCI Promatec will work with you to ensure that you receive the best product for your specific application.

We offer a full line of our own specially-blended penetration sealants. Additionally, we are a distributor and installer worldwide — in some cases, on an exclusive basis — for many of the best-known fire protection product manufacturers, including 3M Interam TM Flexible Wrap Systems, Dow Corning, GE, Carboline and Promat products.

High-Density Silicone Elastomer (HDSE)

HDSE is a high-density, two-part silicone elastomer developed and manufactured exclusively by PCI Promatec. Primarily developed as a fire sealant capable of providing a high degree of gamma radiation shielding, HDSE is supplied at a minimum density of 147 FT³. HDSE is also an excellent flood seal material (up to 40 psi pressure – CTP-1081). Further, relative to other sealants, this material acts as a heat sink, (thereby reducing the concern for cable derating).  Installed as a liquid, by hand, or machine, this ensures a complete fill in and around penetrating elements. Cured, it exhibits a durable, damage-resistant exterior surface that is easy to decontaminate.

Radiation Resistance

HDSE has been subjected to substantial radiation exposure levels (5 x 107 Rads Gamma) with no significant changes reported to the material’s physical properties. Base material has undergone exposures as high as 7.13 x 108.

Fire Qualification

Successful full-scale fire testing has been performed for a variety of design configurations at nationally recognized laboratories, to numerous standards. A depth as little as 8″ is all that is required for a 3-hour fire rating.

Repairability

HDSE can be selectively removed with relative ease using blunt non-conductive tools and devices. Additions or deletions of elements can be easily accomplished, and new HDSE material can then be applied to previously cured material to become an integral matrix with the already installed HDSE.

Packaging

HDSE is supplied in 150 lb. sets consisting of two six-gallon containers, yielding approximately 1 cubic foot of cured material.

Cure Time

Cure time for the HDSE can be varied from 10 minutes to 4 hours. Custom cure times can be requested.

SF-150NH: High-Density Silicone Elastomer

SF-150NH is a high-density two-part silicone elastomer, originally available from Brand Insulation Services (BISCO), now manufactured exclusively by PCI Promatec. The SF-150NH provides a high degree of gamma radiation shielding, supplied at a minimum density of 147 FT³. SF-150NH is also an excellent flood seal material (up to 40 psi pressure – Ref M-179). Further, relative to other sealants, this material acts as a heat sink, thereby reducing the concern for cable derating. Installed as a liquid, by hand, or machine, this ensures a complete fill in and around penetrating elements. Cured, it exhibits a durable, damage-resistant exterior rated excellent for decontaminability.

Radiation Resistance

SF-150NH has been subjected to substantial radiation exposure levels (1 x 108 Rads Gamma) with no significant changes reported to the material’s physical properties. Base material has undergone exposures as high as 7.13 x 108.

Fire Qualification

Successful full-scale fire testing has been performed for a variety of design configurations at nationally recognized laboratories, to numerous standards. A 12” depth is all that is required for a 3-hour fire rating.

Repairability

SF-150NH can be selectively removed with relative ease using blunt non-conductive tools and devices. Additions or deletions of elements can be easily accomplished, and new SF-150NH material can then be applied to previously cured material to become an integral matrix with the already installed SF-150NH.

Packaging

SF-150NH is supplied in 100 lb. sets consisting of one five and one six-gallon container, yielding approximately 0.66 cubic foot of cured material.

Cure Time

Cure time for the SF-150NH is approximately 8 hours.

RADFLEX: 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.

Repairability

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.

High-Density Sealants

HDSE™ is a high-density silicone elastomer developed and manufactured exclusively by PCI Promatec. Primarily developed as a fire sealant capable of providing a high degree of gamma radiation shielding, HDSE™ is also an excellent flood seal material (up to 30 psi pressure). Further, relative to other sealants, this material acts as a heat sink, thereby reducing the concern for cable derating. Installed as a liquid, this ensures a complete fill in and around penetrating elements. Cured, it exhibits a durable, damage-resistant exterior surface that is easy to decontaminate.
