ZERO Product Catalog & CAD Library

If you're looking for a reliable U.S. source of top-quality intumescent firestopping -- or your customers' specialized needs require custom solutions -- you will find an ideal partner in ZERO.

We produce our INTUMET™ intumescent material and manufacture our firestopping products right at our U.S. headquarters in Bronx, N.Y. In fact, we are the ONLY major U.S. intumescent manufacturer.

Our location and capabilities offer a unique package of benefits for our OEM (original equipment manufacturer) partners in the U.S.:

	immediate availability of standard materials and products
	fast turnaround on custom orders
	economical pricing
	predictable costs -- no variables from currency exchange fluctuations

Intumescence for Every Application

We also offer unsurpassed value through our advanced proprietary intumescent technology. See Physical Properties chart below for details about our standard intumescent formulations.

ZERO's SOFT PUFF™ INTUMET™ is a rubber-matrix material that begins intumescing at the relatively low temperatures where organic materials begin to emit combustible and noxious gases. It expands gradually with low force and forms a firm char. For applications that call for more forceful expansion at higher temperatures, you can choose from several standard INTUMET™ HARD PUFF materials. See Material Definitions table below for a comparison.

The bottom line is intumescent technology that allows virtually unlimited product design flexibility. Working with OEM partners, we continue to develop customized intumescent formulations. If you need something special, let's talk about it.

ZERO's firestopping capabilities include:

Pipe wraps

Sprays and paints

Tubing for electrical box fire containment

Tape

Impregnated paper

Cable protection

Expansion joint seals

Soffit protection for firestorm regions

Firestopping for New and Retrofit Construction

ZERO welcomes inquiries from any building team member for assistance in solving fire protection challenges in firewalls, as well as electrical and plumbing through-penetrations.

We can work with you to refine or overhaul product design to satisfy code requirements or testing agency parameters. We can also collaborate in testing for F ratings (flame penetration), T ratings (temperature rise) and L ratings (air leakage) under U.S. standards:

	ASTM International E 814 Standard Test Method for Fire Tests of Through-Penetration Fire Stops
	Underwriters Laboratories UL 1479, Standard for Fire Tests of Through-Penetration Fire stops

Firestopping Wherever You Need It

We are actively seeking OEM partners for cooperative research, development and testing to explore applications of mutual interest. Contact us to discuss opportunities for innovative, cost-effective fireproofing solutions for any industry, including:

	Shipbuilding
	Bridge-building
	Train and subway construction

INTUMET Material Definitions

SOFT PUFF™ begins intumescing at relatively low temperatures. Expands gradually with low force and forms a firm char. It has a reservoir for continued expansion.

HARD PUFF begins intumescing at higher temperatures. Expands with strong force. It has a high intumescent capacity, dissipating char, but no reservoir for additional expansion.

INTUMET	Very low temperature activation	Controlled high-volume expansion	Multi or controlled directional	Any size Any color	Does not sustain flame	Moisture resistant	Paintable and chemically inert	Non-carcinogenic	Long life (no deterioration)	No odor	Hard char
