About us
Founded in 2022, Opruite is located at the source of the "Sichuan-Tibet Line in Southern Anhui", in the port Yongdian Zhichuang City Industrial Park, Ningguo City, Xuancheng City, Anhui Province. The management team has attracted more than 10 years of senior personnel in the thermosetting composite materials industry, bringing together talents in the fields of manufacturing, technology and business, and the service team has gathered professional and technical personnel in the thermosetting composite materials industry for more than 10 years. The company has a technical team from Europe and the United States, using industry-leading equipment and professional testing personnel, to achieve customized production and sales of BMC/SMC thermosetting composite materials.
Product Introduction
——
Composites generally have two parts: matrix material and reinforcing material (such as resin and glass fiber).
It is made up of two or more simple materials mixed together and can be organically combined with each other to form a new insulating material.
BMC/SMC is one of the composite materials, which is composed of unsaturated polyester resin as the matrix and glass fiber
reinforced material and combined with other necessary components.
BMC polyester/vinyl ester group molding compounds
——
BMC (bulk molding compound) or DMC (dough molding compound), also known as bulk molding compound (formerly known as BT-3), is a mass chopped fiber-reinforced thermosetting composite. Nowadays in the United States, Japan and China, BMC and DMC usually refer to the same material, according to the definition of SPI in the United States, BMC is chemically thickened DMC.
SMC polyester/vinyl ester base sheet molding compounds
——
SMC is the abbreviation of Sheet Molding Compound, that is, sheet molding compound, the main raw materials are unsaturated polyester resin, thickener, initiator, crosslinking agent, low shrinkage additives, fillers, internal release agents, colorants and other mixtures impregnated with chopped glass fiber roving or glass fiber felt, and the two surfaces are combined with protective film (polyethylene or polypropylene film) to form a sheet molding material and various additives.
Product Features:
