| 2. Intumescent Acrylic Firestop Sealant | Intumescent acrylic | Up to 4 hours in approved penetration-sealing systems | Usually 7.5% to 12.5%, depending on the tested system | Approximately −20°C to 82°C | Combustible pipes, insulated non-metallic pipes, cable trays, and mixed penetrations | ASTM E814 / UL 1479; EN 1366-3; EN 13501-2 classification where applicable | Expands when heated and helps protect openings created by combustible services |
| 3. High-Movement Silicone Firestop Sealant | Neutral-cure silicone | Up to 4 hours in tested joint and penetration assemblies | Commonly ±25% or greater, subject to the tested joint design | Approximately −40°C to 149°C | Perimeter joints, curtain-wall interfaces, floor-to-wall joints, and dynamic movement gaps | ASTM E1966 / UL 2079; ASTM E814 / UL 1479; EN 1366-4 for linear joint seals | Excellent weathering, UV, moisture, and movement resistance for demanding locations |
| 4. Elastomeric Firestop Sealant | Water-based or solvent-free elastomeric polymer | Up to 3 or 4 hours in listed assemblies | Typically up to 12.5%, depending on formulation and joint geometry | Approximately −20°C to 82°C | Construction joints, cable penetrations, metal pipes, and service openings | ASTM E814 / UL 1479; ASTM E1966 / UL 2079 where joint movement is tested | Balances flexibility, adhesion, smoke sealing, and installation convenience |
| 5. Graphite-Based Intumescent Sealant | Graphite-filled intumescent compound | Up to 3 hours in approved penetration systems | Generally low to moderate movement; often up to 7.5% | Approximately −20°C to 82°C | Combustible plastic pipes, cable penetrations, and irregular service openings | ASTM E814 / UL 1479; EN 1366-3; EN 13501-2 where classified | Strong expansion response for closing gaps after combustible components soften or burn away |
| 6. Hybrid Polymer Firestop Sealant | Moisture-curing hybrid polymer | Commonly 2 to 3 hours when supported by a tested assembly | Often approximately ±12.5% to ±20% | Approximately −30°C to 90°C | Interior and exterior linear joints, mixed-substrate interfaces, and renovation work | ASTM E1966 / UL 2079 or EN 1366-4 when specifically tested; project certification is essential | Good adhesion to concrete, masonry, metal, and selected plastics with low odor |
| 7. Exterior-Rated Silicone Joint Firestop Sealant | Fire-rated silicone elastomer | Up to 4 hours for tested perimeter, façade, and floor-line joint systems | Commonly ±25% to ±50%, depending on the certified assembly | Approximately −50°C to 150°C | Building façades, curtain walls, exterior wall joints, and high-exposure construction joints | ASTM E1966 / UL 2079; EN 1366-4; ASTM C920 for relevant sealant properties | Best suited to high UV, rain, thermal cycling, and façade movement conditions |
