HSQY PLASTIC GROUP We have a strong and advanced QC system and take acrylic as an example. The storage, handling, and processing of the chemicals that make acrylic plastics are done under controlled environmental conditions to prevent contamination of the material or unsafe chemical reactions. The control of temperature is especially critical to the polymerization process. Even the initial temperatures of the monomer and catalyst are controlled before they are introduced into the mold. During the entire process, the temperature of the reacting material is monitored and controlled to ensure the heating and cooling cycles are the proper temperature and duration.Samples of finished acrylic materials are also given periodic laboratory analysis to confirm physical, optical, and chemical properties.
