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.

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® 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® 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.

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.

ISOLENE® 40-S is a low-molecular-weight liquid polymer derived from synthetic polyisoprene rubber. It offers the performance of natural rubber with the added benefit of a lighter color and none of the natural impurities inherent in natural rubber products. ISOLENE® 40-S is a lower viscosity liquid than the other ISOLENE® liquid rubber products. It is a translucent, honey-colored liquid in bulk form and virtually clear in a thin film.

H.B. Fuller PHOTOCAP® 3650 is an ultrafast-curing, PID-resistant thermoset polyolefin encapsulant with enhanced UV protection to ensure backsheet longevity. It has a low MVTR (moisture vapor transmission rate), a short lamination cycle, and excellent light transmission with no acetic acid concerns.

H.B. Fuller PHOTOCAP® 3610 is an ultra-fast cure and PID resistant thermoset polyolefin encapsulant with HLT™ higher light transmission in the UV wavelength region to allow greater power generation with blue light-sensitive photovoltaic devices. It has a low MVTR, a short lamination cycle, and excellent light transmission with no acetic acid concerns.

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® 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.

Elvace® 725 is a vinyl acetate-ethylene copolymer known for forming tough, permanently flexible polymer films. It offers excellent viscosity build with plasticizer addition, high wet tack, and resistance to hydrolysis. With low residual vinyl acetate monomer levels and good adhesion to challenging substrates, it is suitable for extrusion applications. Designed for low VOC adhesives, it works well on various paper and treated film substrates.

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.

Elvace® 732 is a vinyl acetate-ethylene copolymer that forms tough, permanently flexible polymer films. It features excellent viscosity build with plasticizer addition, short bond development times, and excellent machining properties. The remoistenable film offers resistance to plasticizer migration but has poor borax tolerance. It is designed as a base for general-purpose and specialty adhesives, ensuring easy clean-up and versatile performance.

ISOLENE® 400-S is a low-molecular-weight liquid polymer derived from synthetic polyisoprene rubber. It offers the performance and processing characteristics of natural rubber with the added benefit of a lighter color and none of the natural impurities inherent in natural rubber products. ISOLENE® 400-S is a high-viscosity liquid at room temperature. It is a translucent, honey-colored liquid in bulk form and virtually clear in a thin film.

H.B. Fuller PHOTOCAP® 6048 is a thermoplastic, non-EVA-based encapsulating film designed for use in thin film modules.  It has a low MVTR (moisture vapor transmission rate), a short lamination cycle, and good creep resistance with proven longevity in the field.
