RayBlock Heat Shrink Sealing Kits

Provide consistent sealing with RayBlock heat shrink sealing kits

Are you looking for a product to seal cable bundles, connector backs, or grommets? Rayblock heat shrink sealing kits are an excellent solution!

TE Connectivity’s (TE) RayBlock heat shrink sealing kits are designed to provide consistent sealing for cable bundles and the back of connectors or grommets. The wires in the bundle are placed within the channels of a specially formulated hot-melt adhesive profile, and then covered by dual wall, heat-shrinkable tubing with a flame-retardant radiation-crosslinked outer wall and hot-melt-adhesive inner wall. When the tubing is heated, the hot-melt adhesive melts and the tubing shrinks, forcing the molten adhesive to fill all the voids within the wire bundle and tubing. The result is a solid plug of adhesive molded around each wire in the bundle, creating a moisture-resistant seal.

Key Features

  • Continuous operating temperature from –40°C up to +85°C or +105°C (model dependent)
  • Minimum shrink temperature: 80°C
  • Minimum full recovery temperature: 110°C
  • Flame retarded (tubing only)
  • 4:1 shrink ratio
  • Fluid resistant
  • Excellent electrical insulation
  • Broad range of sizes to accommodate many sizes of wire bundles
