They are also used in space applications where low outgassing is critical. These special requirements are detailed in Table 5. The operating temperature for this product is -55C to +225C (-67 to +437F). This system is a computerised method of identifying items by printing a mark on HT-SCE and HT-CT product ranges which is permanent upon printing. This system is not recommended where strain relief properties are required. The marker sleeves shall be fabricated from cross linked polymer tubing. Supplied flattened and spooled in a continuous tube as HT-CT or mounted on a carrier as HT-SCE. All sizes have a 2:1 shrink ratio except size 3/32 which has a 3:1 shrink ratio (refer to Table 1 for more details).
