At present, there is a high temperature resistant flame retardant additive for full transparent polycarbonate, which is a high temperature resistant flame retardant additive, does not contain bromine and chlorine compounds, has high solubility in polycarbonate, and is used in a small amount for production. A fully transparent grade of polycarbonate with little effect on the physical properties of the resin itself. Its chemical and thermal properties are very stable and can withstand temperatures up to 450 ° C, so it can be used in engineering plastics that require high temperature processing.
In the production of such a high temperature resistant flame retardant additive, the raw material is added to the mixing kettle according to the ratio. After extrusion, a fully transparent grade polycarbonate can be obtained. It is usually better to use twin-screw extrusion. The chemical and thermal properties of this product are very stable, and the effective addition amount is as low as 0.06-0.1 (weight%).
The high temperature resistant flame retardant additive will decompose under the high temperature condition, absorb the combustion factor, and achieve the flame retardant effect. Because it does not contain environmentally polluting elements such as chlorobromide, it is also an environmental product.www.china-zhufengchem.com
