Rogers Arlon R3781-920-##R##-P0 Silicone Rubber
Categories:	Polymer; Tape; Thermoset; Rubber or Thermoset Elastomer (TSE); Silicone; Silicone Rubber
Material Notes:	This fusible silicone tape is specially formulated to yield improved flexibility, elongation and elastic recovery at low operating temperature (-70°C to -100°C) where standard fusible silicone tapes become highly crystalline and lose their desirable elastomeric properties. Interleave: 3 mil PE; Rubber: Cured self fusing silicone. Information provided by Arlon Silicone Technologies; now a part of Rogers Corporation.
