Abrasion Scratch Resistant Acrylic Sheets
Abrasion resistant acrylic sheets are extruded or casted sheet which offers excellent optical clarity and high impact strength with abrasion and chemical resistant properties. It is produced by applying a very hard, polysilicate coating to an optical acrylic substrate. It is available with coating on one side or two sides. While two-side coated sheet provides maximum protection, one-side coated sheet offers economical advantages for applications where only one side of the sheet is exposed. In addition, the un-coated side is ideal for silk screening.
Abrasion resistant acrylic sheets that one side coated is a great glass replacement for flat panel monitors, signs and LCD screens, and framing. Two side coated is suitable for interior and exterior break resistant windows and such so on.
1. Key Features:
A. The surface is hard, durable and abrasion-resistant.
B. 100% Brand New PMMA Material; Completely clear acrylic.
C. Perfect material for surface protections, glazing, guard screens, displays and more.
D. Easily maintained with soap and warm water –no harsh chemicals needed
F. Supplied with protective film on both sides.
G. Perfect transparency and the light transmittance with 90%.
H. Suitable for the fabrication of electroplating, hard coating and Screen printing .
NOTE:
ABRASION RESISTANT ACRYLIC SHEET IS NOT RECOMMENDED FOR HEAT BENDING.
Since The AR Coating Is Chemically Resistant, It Cannot Be Glued With Acrylic Cement. Glue Only Uncoated Sides And Edges.

3. Testing Method：
The excellent scratch resistance can be confirmed by the pencil hardness test.
This test involves a pencil being clamped into a device at a 45-degree angle to the surface to be tested, and then being slid across the surface of the test sample. The first pencil hardness (starting with the highest hardness) whose tip does not leave a noticeable scratch is considered the characteristic physical variable. For comparison, conventional acrylic sheet has a pencil hardness rating of HB, while abrasion resistant acrylic sheets has a 5H hardness rating, which is six degrees higher.

The hard coating provides acrylic sheets with a surface that has 40 times the abrasion resistance of uncoated acrylic, making it an attractive material for applications that require the safety and frequent public contact and involved heavy use, such as displays, exhibits and fixtures, abrasion resistant sheet will help maintain a “like-new” premium appearance much longer.
