A) UPR stands for Unsaturated Polyester Resin.

B) MMA stands for Methyl Methacrylate.

C) [AL(OH)3] represents Hydrated Aluminum Oxide Powder.

Modified acrylic solid surface primarily comprises UPR, MMA, and [AL(OH)3], with a composition ratio of approximately 8-10% MMA, around 26% UPR (including 0.3% Anti-UV resin), and 63% [AL(OH)3].

100% acrylic solid surface consists mainly of 43% MMA, 55% [AL(OH)3], and natural pigments.

100% acrylic solid surface is harder than modified acrylic. The Barthel hardness of modified acrylic ranges from about 58 to 60, while 100% acrylic has a hardness of approximately 70.

Modified acrylic solid surface material can be bent at temperatures exceeding 80 degrees Celsius, with a bending diameter of about 450mm.

100% acrylic solid surface, on the other hand, can be bent at temperatures exceeding 120 degrees Celsius, and it can be shaped into various forms within about one hour.

100% acrylic solid surface exhibits superior shock resistance, pressure resistance, bending resistance, and absorbency compared to modified acrylic solid surface.

100% acrylic solid surface offers better resistance to yellowing, heat, soiling, acidity, and basicity compared to modified acrylic.

To differentiate between 100% acrylic and modified acrylic:

1. Conduct a burn test. 100% acrylic will emit a pleasant scent, while modified acrylic will have an odor.
2. Attempt to cut the sheets. 100% acrylic is easy to cut, whereas modified acrylic is not. Additionally, when cutting 100% acrylic, the material resembles snowflakes, while modified acrylic produces more dust.
3. Pour boiling water on the surface. The surface of modified acrylic will turn white, whereas 100% acrylic will remain unaffected.
