| KALAR® 5281 is a partially cross-linked butyl rubber compound pelletized for easy handling. KALAR® 5281 is modified with ethylene vinyl acetate (EVA) copolymer to improve lower temperature toughness and higher temperature processing. KALAR® products feature all the performance attributes expected of butyl rubber. KALAR® 5281 is light amber to yellow in color and is among the tightest cross-linked butyl rubber of the KALAR® products. It is designed as the starting point for applications that require the maximum resistance to creep and slump. Features and Benefits: KALAR® 5281 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
