2.5:1 Shrink Ratio

Market/Applications

  • OEM
  • Industrial
  • Aerospace Defense

 

Ordering

  • Select a dimension which will shrink snugly over the component to be covered. If recovery is restricted the resulting wall thickness will be less than specified.
  • Select Options:
    • Color: Black (BK)
    • Lengths: 48 in (1.2 m) continuous reels or cut pieces
  • Please specify the product name, order number and options you require.
  • Order Example: CHM 140, 0375, black, unprinted, 500 ft reel

Please contact your Customer Service Representative for information on custom colors, sizes, lengths and material data sheet.
