Description
This clear acrylic sheets are surface coated with an extremely thin and highly abrasion resistant dissipative film which keeps the transparency and the working properties of acrylic sheets unvaried. Equipped with a protection film on both sides can avoid damages during transportation and storage.
Advantages
1. Perfect transparency and the light transmittance with 93%;
2. Excellent electrical insulation;
3. High plasticity, Processing and shaping easier;
4. Water-proof, anti-UV;
5. Strong surface hardness and good weather resisting property;
Applications
1. Dust-free room and clean room spacer, observation window shield;
2. Fixture and clamp for electronic tests;
3.Lampbox ,sign-board ,indicator, showing shelf ;
4.Bath room, art work, cosmetics, bracket;
5. Daylight lamp, ceiling lamp, lampshade;
