KALENE® 1300 is a low-molecular-weight liquid polymer derived by the depolymerization of butyl rubber. It vulcanizes at either ambient or elevated temperatures with the standard curatives for butyl rubber. KALENE® 1300 is light gray and contains no solvents or additives. KALENE® 1300 has the higher viscosity of the two KALENE® grades available and is the ideal choice for applications requiring the maximum retention of physical properties at the expense of a maximum reduction in viscosity. KALENE® 1300 is the preferred liquid butyl rubber for adhesive applications and a reactive additive to ordinary butyl rubber. KALENE® 1300 provides gas impermeability, chemical resistance, moisture resistance, good electrical properties, and excellent vibration and sound damping qualities.

KALAR® 5280 is a partially cross-linked butyl rubber compound pelletized for easy handling. KALAR® products feature all the performance attributes expected of butyl rubber. KALAR® 5280 is amber in color and is among the tightest cross-linked butyl rubbers of the KALAR® products. It is designed as the starting point for applications that require the maximum resistance to creep and slump. KALAR® 5280 provides the most resistance to flow at high temperatures.

KALAR® 5275 is a partially cross-linked butyl rubber compound pelletized for easy handling. KALAR® products feature all the performance attributes expected of butyl rubber. KALAR® 5275 is amber in color and is among the tightest cross-linked butyl rubbers of the KALAR® products. It is designed as the starting point for applications that require the maximum resistance to creep and slump. KALAR® 5275 provides good resistance to flow at high temperatures.

KALENE® 800 is a low-molecular-weight liquid polymer derived by the depolymerization of butyl rubber. It vulcanizes at either ambient or elevated temperatures with the standard curatives for butyl rubber. KALENE® 800 is light gray and contains no solvents or additives. KALENE® 800 has the lower viscosity of the two KALENE® grades available and is the preferred liquid butyl rubber for coating applications. KALENE® 800 provides gas impermeability, chemical resistance, moisture resistance, good electrical properties, and excellent vibration/sound damping qualities.

KALAR® 5281 is a partially cross-linked butyl rubber compound pelletized for easy handling. This product 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 rubbers of the KALAR® products. It is designed as the starting point for applications that require the maximum resistance to creep and slump.

KALAR® 5265 is a partially cross-linked butyl rubber compound pelletized for easy handling. KALAR® products feature all the performance attributes expected of butyl rubber. KALAR® 5265 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.

KALAR® 5277 is a partially cross-linked butyl rubber compound pelletized for easy handling. KALAR® products feature all the performance attributes expected of butyl rubber. KALAR® 5277 is amber in color and is among the tightest cross-linked butyl rubbers of the KALAR® products. It is designed as the starting point for applications that require the maximum resistance to creep and slump.

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.

KALAR® 5215 is a partially cross-linked butyl rubber compound pelletized for easy handling. KALAR® products feature all the performance attributes expected of butyl rubber. KALAR® 5215 is off-white in color and is a moderately cross-linked butyl rubber, providing an excellent butyl intermediate base for general-purpose sealants and tapes.
