Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Alumina ceramics commonly have a melting point of up to 167 ℃, which is the only plastic box that can be safely placed in a microwave oven and can be reused after careful cleaning. It is important to note that while some microwave lunch boxes may claim to be microwave-safe with a body made of No. 5 PP, the Alumina Ceramic Ring offers enhanced temperature resistance, with special PP designed specifically for microwave use, withstanding temperatures up to 120 ℃ and as low as -20 ℃. Manufacturing. Since PET cannot withstand high temperatures, it cannot be placed in a microwave oven together with the box. To be safe, remove the lid of the container before putting it in the microwave. Note: When putting it in the microwave, remove the lid. "No. 6" PS is often used in: bowls of instant noodle boxes and fast food boxes. Don't use a microwave to cook instant noodles in a bowl: it is heat-resistant and cold-resistant, but cannot be placed in a microwave to avoid the release of chemicals due to excessive temperature (released at 70°C). And can not be used to contain strong acids (such as orange juice), strong alkaline substances, because it will decompose polystyrene, which is not good for the human body, and easily cause cancer. Therefore, you should try to avoid using fast food boxes to pack hot food. Note: Do not use the microwave to cook instant noodles. Other types of "No. 7" PC are commonly used in: kettles, water cups, and baby bottles. Use: A material that is used in large quantities, especially used in baby bottles, which is controversial because of its content of bisphenol A. Lin Hanhua, an associate professor in the Department of Biology and Chemistry of the City University of Hong Kong, said that in theory, as long as 100% of BPA is converted into a plastic structure during the production of PC, it means that the product is completely free of BPA, let alone released. However, if a small amount of bisphenol A is not converted into the plastic structure of PC, it may be released into food or drink. Therefore, be careful, and take extra care when using this plastic container.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
