| 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. Features and Benefits: KALAR® 5263 contains no filler and its tenacity is due to the degree of cross-linking; not reinforcing fillers. This feature permits the compounder the widest formulating latitude. Other key performance benefits include: - Elimination of butyl rubber pre-mastication
- Pellets may be metered to facilitate mixing
- Requires no vulcanization
- Readily acceptable in a wide range of solvents
- Extends with high levels of fillers and plasticizers
- Compatible with a wide choice of compounding ingredients
- Creep and cold-flow resistance
- Compounding economy
