KALAR Cross-Linked Butyl Pellets

Elementis Performance Polymersoss-Linked Butyl Pellets
The Kalar products are partially cross-linked butyl rubber compounds. They are pellitized for easy handling. They feature the performance benefits of butyl rubber, the processing ease of pellets, and the ability to maintain their properties with a high level of fillers and plasticizers.

The Kalar products provide act as the base resin or as a performance additive for adhesives and sealants that require the properties of butyl rubber. These benefits include excellent chemical resistance, moisture & gas impermeability, good electrical properties and resistance to aging. They also impart excellent resistance to creep and flow.

The Kalar products offer several processing benefits to formulators of butyl systems:

• Eliminates butyl rubber premastication
  
• Requires no vulcanization
  
• Dissolves easily in a wide range of solvents
  
• Extends with high levels of fillers and plasiticizers
  
• Blends readily with other compounding ingredients
  

Typical Applications
The principal applications for Kalar cross-linked butyl are as sealants for commercial and industrial markets:

• Industrial sealant tape
  
• Architectural glazing tape
  
• Automotive windshield tape
  
• Automotive sealant and sound deadening compound
  
• Tire sealant
  
• High-strength thermoplastic sealant
  
• Weather-proofing sealant tape
  

Kalar products impart the benefits of butyl rubber to many other applications. These applications incorporate Kalar products in concentrations that range from a few percent to the major part of the formulation:

• Hot-melt glazing compounds
  
• Solvent release coatings
  
• Caulks
  
• Construction adhesives
  
• Tank linings and roof coatings
  

The processing advantages make the Kalar products a convenient tool for compounders. They use Kalar products in small concentrations in conventional systems:

• Processing aid for butyl rubber
  
• Enhance green strength in butyl and EPDM compounds
