Product Description
Solid Silicone KB3000S is continuously manufactured through calendering processes. Its exceptional heat and chemical resistance enables broad applicability. These sheets deliver long-term service at 180°C, withstand 200°C+ environments for weeks while retaining elasticity, and endure instantaneous exposure exceeding 300°C. To enhance toughness and tensile strength, composite versions incorporate fabric reinforcement cores, including polyester fabric, nylon mesh, fiberglass cloth, and PTFE fabric.
Exhibits minimal degradation of electrical properties when exposed to moisture or elevated temperatures. Even during short-circuit events, carbonization products (including carbon dioxide) maintain insulating properties, ensuring continuous operation of electrical equipment. This qualifies the material for producing wire, cable, and lead wire.
Withstands repeated sterilization cycles under harsh conditions. Demonstrates high resilience with low permanent compression set (≤50% after 48h at 200°C per ASTM D395). Dielectric strength ranges from 20–25 kV/mm.
Aliphatic, aromatic, and chlorinated hydrocarbon solvents
Petroleum-based fuels and hydraulic fluids
Synthetic oils (including ester-based lubricants and silicate ester hydraulic fluids) at ambient temperatures
