Kodak Estar Heat Stabilized (HS) Films are a premium polyester (PET) produced to maintain consistent dimensional stability (<0.2%) at temperatures of 150°C -30 minutes (ASTM D.1204). Kodak Estar HS films are manufactured with minimal surface contact, and our inline heat stabilization process results in a high quality, dimensionally stable, exceptionally uniform, flexible, optically clear and cost-effective material. Films can be coated on one or both sides in 76 μm, 102 μm, 127 μm and 178 μm thicknesses.

Optical-grade Surface Quality
- A cushion of air transports the film throughout the stretching process. Films are then scanned to meet the stringent requirements for high optics applications.
- Less than one micron thick adhesion primer. Films can be coated with an adhesion-promoting primer and winding aid.
- Minimum shrinkage in both the machine direction (MD) < 0.1% and transverse direction (TD) < 0.2%.
- Range of thicknesses 76 μm, 102 μm, 127 μm and 178 μm.
- Greater than 90% transmittance with less than 1% haze.
Optima Roll Intergrity
- The edge of the roll is free of nicks, cuts or visible telescoping greater than ± 6.3 mm (0.25 inches).
- The roll contains no gage bands to visibly distort the film surface.
Consistent Product Quality
- Kodak inspects material during the manufacturing process using in-line scanners to detect, correct, and deliver material that meets or exceeds specifications.
- Kodak quality technicians consistently evaluate sample product quality using internal and external standards to confirm quality standards are met.
