Melamine molding compound (MMC), commonly known as melamine powder and A5 material, is a molding compound made of melamine formaldehyde resin as the base material, cellulose and minerals as fillers, and lubricants, curing agents, hardeners, pigments and other additives. Suitable for molding methods, this series is used to manufacture all kinds of heat-resistant and water-resistant bowls, chopsticks, plates and other dining utensils.
Color: can be arbitrarily colored, customers can color according to the Pantone color card number or provide real samples for color scheme.
