BISCO® IF-200 Tear Resistant
BISCO® IF-200 is a specialty silicone foam composite consisting of a fiberglass support layer directly bonded to BF-1000 silicone foam, fixed at 0.197″ thickness with an areal density of 0.29 lb/ft², designed to provide resistance against tear and abrasion while retaining flexibility. The material passes cohesive failure testing and FMVSS302 for flame compliance. It is suited for automotive, HVAC, aerospace, rail, and mechanical applications exposed to vibration, wear, or mechanical stress.

BISCO® IF-200 is a tear-resistant specialty silicone foam composite in which a fiberglass support layer is directly bonded to BF-1000 silicone foam. The fiberglass reinforcement layer imparts structural resistance to tear and abrasion that standard unreinforced silicone foam cannot provide, while the BF-1000 foam base retains the flexibility and compressibility required for installation in gasketed and cushioned assemblies.
At a fixed thickness of 0.197″ and areal density of 0.29 lb/ft², it is a defined-geometry product suited for die-cut gasket and sealing components in confined spaces.
The composite construction passes cohesive failure testing, confirming that the bond between the fiberglass layer and the foam base does not delaminate under stress. FMVSS302 is passed for automotive and transit flame compliance.
The material is designed to withstand harsh environments and provides a supportive yet flexible base for installation in abrasion-prone interfaces including mechanical mounts, HVAC gaskets, automotive heat shield assemblies, and sealing components in rail and aerospace applications subject to vibration, wear, or mechanical stress.
Compliant with FMVSS302.
What differentiates IF-200 from unreinforced BISCO® silicone foam grades?
IF-200 is the only BISCO® silicone foam composite in this series that bonds a fiberglass support layer directly to the BF-1000 foam base. This construction provides tear and abrasion resistance that unreinforced silicone foam cannot deliver, making it the appropriate selection for applications where the foam will be subjected to mechanical stress, abrasion, or installation forces that would propagate tears in a standard foam. The fiberglass layer also provides dimensional stability without sacrificing the flexibility of the BF-1000 foam base.
Why is hardness important for a reinforced silicone foam used in mechanical and sealing applications?
Note: No hardness or compression force deflection value is listed on the IF-200 TDS. The most prominent differentiating mechanical property for this product is cohesive failure performance. Cohesive failure testing confirms that the bond between the fiberglass reinforcement layer and the BF-1000 foam base holds under stress without delamination. In gasket, heat shield, and mechanical mount applications, a composite that delaminates under load loses its structural integrity and fails to perform its sealing or protective function. IF-200's cohesive failure Pass result confirms the laminate bond remains intact under the mechanical demands of its intended applications.
What is the operating temperature range for IF-200?
No operating or service temperature range is listed on the IF-200 TDS. End-users should contact H-O Products for guidance on temperature performance in specific applications.
Is IF-200 suitable for automotive flame-rated environments?
Yes. IF-200 passes FMVSS302 for automotive and transit flame compliance as listed on the TDS.
How should IF-200 be specified?
Specify grade (IF200SIL), thickness (0.197"), color (White), applicable compliance requirements (FMVSS302), dimensional tolerances, and finished format (sheet, slit roll, or die-cut component).
