Black Factory supplier PE material high shrink ratio Medium wall heat shrink tube with glue for Insulation

Medium wall heat shrink tubing affords maximum reliability for insulating and sealing electrical connections & terminations; including direct burial, URD, and submersible installations. Heavy wall heat shrink tubing is rated for 600V, 90 degree C continuous use. The thicker wall is internally coated with a dual purpose thermoplastic liner for excellent insulating/environmental sealing protection.
*Optional hot melting adhesive liner for complete environmental protection and insulation.
• Meets ICEA & NEMA insulation thickness standard; CSA listed
• 9 standard sizes in black only; standard 4ft. lengths
• Conforms to ANSI C-119.1
• Western Underground Guides 2.4, 2.5
• This adhesive thick wall heat shrink tubing is resistant to common fluids and solvents
• Dielectric strength 500V/MIL (20kv/mm)
• Heated above 120 degrees C, heavy wall heat shrink will shrink unrestricted to 33% (3:1) of its supplied diameter.
