PMMA SHEET
Product features
Excellent transparency and durability
Has higher light transmittance than glass and great weatherability that does not change when exposed
to long-term direct sunlight.
Great color
Better than any other material in terms of various colors and clearness, etc.
Excellent fabrication
Excellent printability and fabricating can increase
the efficiency of work.
Safety
It is safe as the debris do not scatter when breaking.
Non-toxic
Non-toxic when in contact with the human body
for a long time; does not make harmful gas when combusted
Applications
Sound-proof walls
Acrylic Sign board
Clear display stand
Clear partition
