Paint protection film (PPF) is a growing market segment. This thermoplastic urethane (TPU) base “self-healing” film is ideal for protecting surfaces in automotive, aerospace and electronic applications. TPU films are formulated to provide advantages such as abrasion resistance, impact resistance, puncture resistance, hardness, optical clarity, thermal protection and more.

A typical PPF structure, consisting of a 2-mil release liner, mounting adhesive, TPU film, self-healing coating and 2-mil protective film, is manufactured in a two-pass operation. Davis-Standard is equipped to supply an entire PPF system including the extrusion and solution coating lines. The line consists of components such as extruder, controls, turret winder/roll changer, turret unwind, web cleaner, cartridge coater, roll support dryer, and laminator designed per customer requirements. Davis-Standard also offers equipment audits and consultation for a customer’s existing machine set-up to determine what is needed to process a wider range of materials. Laboratory trials determine the quality of new structures, outputs, process parameters, and the feasibility of adding PPF capabilities.

Typical Specifications

Applications – Surface protection, industrial specialties, consumer electronics, transportation
Widths – 62 to 74 inches (1,575 to 1,880mm)
Thickness – 5 to 12 mils
