PHYSICAL PROPERTIES OF SELECTED VERSAFLEX PF TACK LAYER FORMULATIONS
PRODUCT DESCRIPTION
Versaflex™ PF formulations are specially
developed for the manufacture of co-extruded
surface protective films that apply easily, maintain
tack with minimal build, peel smoothly and
remove completely with little-to-no residue or
ghosting.
BENEFITS OF VERSAFLEX PF FOR
SURFACE PROTECTIVE FILMS:
• Customizable tack
• Single-step manufacturing process (co-
extrusion)
• Low volatile organic compound (VOC)
emissions during manufacturing
• Eliminates secondary coating and drying
operations
• Eliminates hazardous liquid chemicals
compared to solvent systems
• Reduces converting costs versus coating
• Reduces energy consumption
MARKETS AND APPLICATIONS
Versaflex PF formulations, customizable
based on desired level of tack, are co-extruded
with protective films to provide just the right
amount of protection during the fabrication,
assembly, shipment, storage and installation of
finished goods in many industries and end-use
applications including:
• Optical films and display panels for consumer
electronics
• Home appliances
• Construction and building materials
• Furniture and cabinetry
• Automotive and other transportation
