BISCO Silicone: Superior Performance Characteristics
- Resistant to temperature extremes, UV, and ozone
- Extremely resilient to mechanical fatigue
- Excellent compression-set resistance
- Flame resistant – Compliance with the most stringent UL flame ratings
BISCO SILICONE PRODUCTS
Cellular Silicone Foams
- UL94 V-0 and HF1 certification rated for flame resistance
- Wide compression force range
- Low compression set under high temperatures
- Temperature range from -55°C to +200°C (-65°F to +400°F)
Marian manufactures custom die cut components using cellular BISCO silicone for sealing, cushioning, insulation, and vibration isolation, particularly in applications with extreme temperatures and exposure to harsh elements and UV. Marian can laminate materials with pressure sensitive adhesive (PSA) on one or both sides.
BF-2000 Extra Soft Silicone Foam
- Typical Density of 10 pounds per cubic foot (PCF)
- Compression force deflection (CFD) 2.5 PSI maximum
- Ideal for transportation applications and areas where low closure force and dust sealing are critical
Sponge Silicones
- General purpose, durable materials for tough environments
BISCO silicones are an excellent choice for gasket and sealing applications in harsh environments requiring a low compression set. Marian die cuts a variety of custom components with the ability to laminate both sides with PSA.
Flame Resistant Sponge Silicone
- Available in three grades: soft, medium, and firm
- Flame resistant with temperature resistance range of -103°F to 450°F
Solid BISCO Silicone
- Grades suitable for acoustic barriers
- Available durometer range of 10 to 70
- Electrically conductive
Marian converts solid silicone materials for high demand gasketing applications. This material is ideal for industrial applications, acoustic, flame, and smoke barriers. Solid silicone material has high tear strength and excellent resistance to fluids.
A2 Sound Barrier Silicone
- Typical density of 1.2-8.2kg/m2
- 62 Shore A Durometer
- Meets the most demanding requirements for flammability, smoke density, and toxicity
