KALAR® 5263 is a partially cross-linked butyl rubber compound pelletized for easy handling. KALAR® products feature all the performance attributes expected of butyl rubber. KALAR® 5263 is amber in color and is a more tightly cross-linked butyl rubber than KALAR® 5215. It is designed as the starting point product for butyl sealants that require higher modulus and/or superior durability at elevated temperatures.
