High Strength Silicone

High strength solid silicone sheeting is a durable, flexible elastomer product engineered for applications requiring superior mechanical properties, especially tensile strength and tear resistance. Unlike standard silicone sheeting, high strength grades are formulated with enhanced polymer chains or reinforcing additives such as silica fillers to improve structural integrity. These sheets typically maintain excellent elongation, compression set resistance, and resilience across a wide temperature range—from -60°C to +230°C—making them ideal for use in harsh environments.

This type of silicone sheeting is commonly used in industrial, automotive, aerospace, and medical applications where repeated stress, impact, or abrasion may occur. Examples include high-performance gaskets, seals, insulation pads, and protective covers. It retains the key benefits of general-purpose silicone—such as UV resistance, non-reactivity, and electrical insulation—while delivering improved physical durability.

Standard thicknesses range from 0.5 mm to several millimeters, and sheets are often available in both cured and uncured forms. They can also meet regulatory standards like FDA or USP Class VI, depending on the formulation. This silicone sheeting is especially valuable in dynamic sealing or cushioning environments where long-term reliability is critical, even under mechanical load or thermal cycling.
