PROFILM 21-031-002 (also known as Oracover) is a high-quality, Fluoro Yellow, heat-shrinkable polyester covering material designed specifically for R/C model aircraft. It is a 2-metre roll, measuring approximately 600mm in width. 

Key Features and Description:

• Color & Finish: Bright Fluorescent Yellow, providing high visibility.
• Material & Durability: Made of genuine polyester, this covering is extremely tough, puncture-resistant, and adds structural rigidity to the model.
• Application & Heat Activation: The adhesive is specially formulated to activate at a relatively low temperature (starting around 80°C), making it safe for application over foam, as well as wood structures.
• Shrinkage & Finish: When applied correctly using a covering iron or heat gun, it shrinks tight to produce an impeccable, wrinkle-free, and sag-free surface.
• Re-positionable: A key feature of Profilm is the ability to remove and re-position the film during application without color-layer separation, allowing for corrections.
• Fuel Resistance: The material is fuel-resistant and can withstand temperatures up to 250°C.
• Multi-layer System: The color pigment is not part of the adhesive layer, meaning it does not leave a tacky, colored residue if removed.
