Product Description
Our MgO is a high active magnesium oxide produced in the form of powder by carefully controlled indirect calcination of milled brucite mineral (magnesium hydroxide).
It is used as a thickening agent in the production of glass-reinforced SMC/BMC composites.
SMC/BMC composition is a mixture of various components: unsaturated polyester or polyacrylic resin, mineral fillers (chalk, flame-retardants), low profile agents, dyes and a thickening agent (chain extender). The thickening agent provides cross-linking and an increase in the viscosity of the composite. Magnesium oxide for this application should have a high specific surface area and a stable particle size distribution.
The correct selection of thickening agent is extremely important in producing a high-quality composite without moulding flaws, cracks and undulations.
