Bergquist Sil-Pad K-10. Bergquist Sil-Pad K-10 is a high performance insulator, combining special film with a filled silicone rubber. The result is a product with good cut-through properties and excellent thermal performance. Sil-Pad K-10 is designed to replace ceramic insulators such as Beryllium Oxide, Boron Nitride and Alumina. Ceramic insulators are expensive and they break easily. Sil-Pad K-10 eliminates breakage and costs much less than ceramics. High performance Kapton® based insulator Tough dielectric carrier against cut-through Designed to replace ceramic insulators Flame rating: UL 94 - V0 Thermal impedance: 0.41°C-in 2 /W (@50 psi) Colour: beige
