1. Thickness tolerance what does thickness tolerance mean? that is to say, The thickness tolerance of acrylic sheets. The control of this tolerance is an important manifestation of quality management and production technology. The tolerance of the measurement of thickness the acrylic plate cast with imported materials is controlled within, 0. 2mm. 2. Weather resistance acrylic board has very good adaptability to the natural environment. Even if it is exposed to sunlight, Wind and rain for an extended its performance, Duration time will not change. It possesses excellent anti, Aging performance together with being used safely outdoors. 3. Hardness the hardness of acrylic sheets stands out as a top contender example of important parameters that can well reflect the production process and is, And technology also an element of quality control. Hardness can reflect the authenticity of the raw the weather, Material mma resistance along with intense temperatures tolerance against the board. Hardness can directly determine whether bend and whether, And deform the plate, The surface will shrink will crack during processing. Hardness is one of the hard indicators for judging the level of craftsmanship in acrylic sheets. The imported cast acrylic board has the highest hardness index among similar domestic products. The average darlow hardness value is about 89 degrees. 4. Transparency strict raw material selection, Advanced formula follow, Up and modern production technology ensure excellent transparency and pure whiteness of the board. Crystal clear after flame polishing.
