KALAR® 5246 is a partially cross-linked butyl rubber compound pelletized for easy handling. KALAR® products feature all the performance attributes expected of butyl rubber. KALAR® 5246 is off-white in color and is the least cross-linked butyl rubber of the KALAR® series of products, providing an excellent butyl intermediate base for general-purpose sealants and tapes. Its controlled cross-linking facilitates easily compounded sealants that can be applied with a minimum of effort. Features and Benefits: KALAR® 5246 has controlled cross-linking which makes it an ideal material for soft sealants with a greater degree of creep and slump resistance. 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
