Process performance
Hardness is one of the parameters that best reflects the production process and technology of cast acrylic sheets, and is an important part of quality control. The hardness can reflect the purity of the raw material MMA, the weather resistance and the high temperature resistance of the plate. The hardness directly affects whether the plate will shrink and bend, and whether the surface will crack during processing. Hardness is one of the hard indicators for judging the quality of acrylic sheets. The cast acrylic sheet has the highest hardness index and an average Rockwell hardness value of 90 degrees.
Acrylic sheet has excellent weather resistance, especially for outdoor applications, ranking among the top of other plastics, and has both good surface hardness and gloss, high processing plasticity, and can be made into various shapes and products. It has a wide variety of plates and rich colors (including translucent swatches), and another feature is that the thick plates can still maintain high transparency.
The main purpose PMMA has the advantages of light weight, low price and easy molding. Its molding methods include casting, injection molding, machining, thermoforming, etc. In particular, injection molding can be mass-produced, with simple process and low cost. Therefore, its application is becoming more and more extensive, and it is widely used in instrumentation parts, automobile lights, optical lenses, transparent pipes, etc.
