1. Raw Materials

The performance of solid surface materials depends on their raw material composition:

• UPR – Unsaturated Polyester Resin
• MMA – Methyl Methacrylate
• Al(OH)₃ – Hydrated Aluminum Oxide Powder

Modified acrylic solid surface consists of approximately 8–10% MMA, 26% UPR (including 0.3% anti-UV resin), and 63% Al(OH)₃.

100% acrylic solid surface is made of 43% MMA, 55% Al(OH)₃, and natural pigments. With no polyester resin, it offers superior performance and consistency.

2. Hardness

100% acrylic solid surface is harder and more durable. Its Barcol hardness is around 70, compared to 58–60 for modified acrylic.

3. Bending Properties

When heated, these materials behave differently:

• Modified acrylic – Bends at over 80°C with a minimum bending diameter of 450mm.
• 100% acrylic – Can be heated above 120°C and shaped into almost any form after one hour of processing.

4. Physical Characteristics

100% acrylic provides better resistance to shock, pressure, bending, and water absorption compared to modified acrylic.

5. Chemical Characteristics

100% acrylic also outperforms modified acrylic in terms of:

• Yellowing resistance
• Heat resistance
• Stain resistance
• Acid and alkali resistance

6. How to Identify 100% Acrylic vs Modified Acrylic

• Burn Test: 100% acrylic releases a light, pleasant scent, while modified acrylic produces an unpleasant odor.
• Cutting Test: 100% acrylic cuts smoothly and produces snowflake-like chips; modified acrylic creates more dust and is harder to cut.
• Boiling Water Test: Modified acrylic turns white when exposed to boiling water, while 100% acrylic remains unchanged.
