PRODUCT DESCRIPTION: BASIC USE: Nelson CPS is a rigid elastromeric fire resistive panel used to seal penetrations and restore the fire rating to floor/ceilings or walls in which an opening has been made for the passage of penetrating items. The material forms a refractory char that retards heat transmission and tightly seals penetrations against flame spread, smoke and toxic fumes. COMPOSITION AND MATERIALS: Nelson CPS is a rigid panel primarily composed of a .300" thick elastomeric sheet bonded to a 28 gauge galvanized steel sheet on one side. The composite sheet is reinforced with hexagonal shaped steel wire mesh and bonded with .003" aluminum foil on the other side. APPLICABLE STANDARDS: UL 1479, Firestops, Fire Tests of Through-Penetration Firestops. ASTM E-814, Fire Tests of Through-Penetration Fire Stops. ASTM E-119, Fire Tests of Building Construction and Materials. APPLICABLE CODES: Nelson CPS meets the requirements of all three model building codes (National Building Code, Uniform Building Code, Standard Building Code), as well as the National Electrical Code, the Life Safety Code, and most state and city codes. For specific approval information contact Nelson. LIMITATION: Nelson CPS should not be exposed to harmful chemicals. Service temperature shall not exceed 180°F. 4. TECHNICAL DATA: Nelson CPS Composite Sheet. Base Elastomeric Sheet Activation Temperature >250°F Volume Increase in Fire 4 to 10 times original size.
