Product Description Melamine formaldehyde molding compound(abbreviation A5)is a king of power heat pressing molding material which main ingredient is melamine.The following are its features:Non-toxic, odorless;Temperature resistance: -30degree ~ +120degree;Bump-resistant;Corrosion-resistant;Beautiful appearance, light and insulation, use safe.Our products are widely used in the production of the following products:The reaction principleMelamine tableware powder is usually formulated by controlling the molar ratio of formaldehyde to triamine atabout 1:2, then heating up to 80 oC.After reaction, the product is a soluble prepolymer resin. The powder product will be formed into a product bycross-linking reaction through high temperature and high pressure.Is melamine toxic ?Everyone may be scared to see melamine compound because its two raw materials, melamine and formaldehyde,are things we particularly hate. However, after the reaction it change into large molecules, it is considered to be non-toxic. With stand temperatureof melamine tableware: -30oC- +120oC. As long as the use temperature is not too high , melamine tableware isnot suitable for use in microwave ovens due to the particularity of the molecular structure of melamine plastic.Trays, dishes, flat plate, fruit plate series, bowl, soup bowl, salad bowl, noodle bowQuality specifications: GB/T9567-2016 Advantages:1 .lt has a good surface hardness gloss insulation heat resistance and water resistance 2.
