Ultra-thin acrylic film
Ultra-thin Optical Grade PMMA Film (Ultra-thin Acrylic Film / DF-PMMA)
This ultra-thin optical film is produced via precision extrusion casting with high-quality polymethyl methacrylate (PMMA, commonly known as acrylic). Its core advantage integrates three key optical and environmental merits of PMMA — high light transmittance, low moisture vapor transmission, and superior weather & UV resistance — into ultra-thin gauges starting from merely 8 μm.
This enables its adoption in optical display stacks and outdoor reflective signage systems, breaking the traditional limitation of PMMA only being used as thick window sheets.
Core Performance Advantages
- High clarity and uniform light transmittance: Meets the requirements of optical stacks for minimal light interference and iridescence.
- Low moisture vapor transmission rate (MVTR): Reduces water vapor ingress into polarizer PVA layers and extends the service life of optical components.
- Excellent weather resistance and UV stability: Suitable for long-term outdoor exposure applications such as road signs, vehicle markings and safety labels.
- Versatile processability: Compatible with printing, lamination, narrow-width slitting and tinting to match downstream coating and bonding procedures.
