Transparent 1000*2000*（1-20mm）High hardness wear-resistant PMMA sheet surface hardness is relatively high, and compared to ordinary PMMA boards, it is more resistant to scratches from hard objects, greatly improving the durability of the board. This high hardness characteristic allows it to maintain a good appearance in various usage environments and is not easily damaged.
High hardness and wear-resistant acrylic sheet is a specially treated organic glass, also known as polymethyl methacrylate (PMMA), which has the following characteristics:
1.High transparency.
2. Weather resistance: It has excellent weather resistance.
3. High surface hardness and gloss.
4. Transparent 1000*2000*（1-20mm）High hardness wear-resistant PMMA sheet has good processing performance.
5. Wear resistance: The wear resistance is close to aluminum, with good stability and resistance to various chemical corrosion.
6. Transparent 1000*2000*（1-20mm）High hardness wear-resistant PMMA sheet has good printability and sprayability.
7. Hardness: Hardness is one of the parameters that best reflects the production process and technology of cast acrylic sheets. High hardness means better wear resistance and weather resistance.
Longer lasting weather resistance performance
Further enhance the resistance to micro cracking characteristics
Equivalent accelerated aging test with 5-year exposure to sunlight (xenon lamp aging)
After 8000 hours of xenon arc lamp irradiation, the yellowing index change in aging test is ≤ 3（GB/T16422.2-2014、HG/T 3862-2006）
