FEP Lay-Flat\u2122 heat shrink tubing can be customized for a range of applications requiring thin walls in comparison to film. Zeus Lay-Flat\u2122 material is also available in long continuous lengths. For shrinkage, FEP Lay-Flat\u2122 can have a \u00b1 10% longitudinal change as it is expanded. This percentage varies by temperature and exposure time, with expansion ratios typically in the range of 1.3:1 to 1.6:1. Expansion ratios can be customized for each application.<\/p>\n
FEP Lay-Flat\u2122 heat shrink tubing easily slides over a mandrel as a sleeve to aid in composite forming. Then, the product can be heated in an oven to achieve a \u201cglove-like fit\u201d that is seamless, protecting the mandrel during cure. The tubing is naturally lubricious, and removing it after cure is easy and more efficient than past film manufacturing practices.<\/p>\n
Our FEP Lay-Flat\u2122 heat shrink tubing is available in diameters ranging from \u00bc\u2033 (6.35 mm) to 3\u00bd\u2033 (89 mm) outside diameter (OD). The tubing is \u201cLay-Flat\u201d to accommodate ease of shipment and is placed on spools where it is compressed and flattened. Wall thickness for our FEP Lay-Flat\u2122\u00a0can range from 0.002\u2033 (0.051 mm) to 0.020\u2033 (0.508 mm) and can be customized to suit application needs. Other resins in heat shrinkable form are available upon request.<\/p>\n
