Butyl Tape for Primary Seal of Insulated Glass

Features & Specifications

Butyl Tape

BST-B Butyl Tape Allows Repeated Spacer Bars Positioning On Glass BST-A Butyl Tape Used for Only One Chance of Spacer Bars Positioning on Glass
  • Pre-extruded butyl tape
  • Wind in disc for easy storage & handle
  • Protected with thin film for further non-sticking handling & processing
  • Perfect water & gas permeable proof
  • No expansive butyl extruding machine required
  • Easy apply on two sides of any spacer bars with simple IG-BTC butyl tape coating tool
  • Coated on curve or shape spacer bars that butyl extruding machine simply could not achieve
  • Standard 0.5mm thick butyl tape
  • Thicker 0.7mm butyl tape is available when insulating tempered glass which is not perfectly flat
  • Available in two types of elasticity
  • BST-A is more elastic for one chance of assembly on glass (repeated positioning of spacer bar would damage butyl tape)
  • BST-B is less elastic allowing repeated spacer bar positioning
  • 2 years shell life when stored under dry & room temperature
