STRUKTOL® TR 451 for Highly Filled Compounds
Designed for extruded and molded applications, TR 451 will improve the overall processing characteristics of your compound.
It is especially effective improving the incorporation of fillers into polyolefin compounds, allowing for higher loadings without sacrificing processing or properties. Compounders using treated fillers may be able to substitute untreated fillers in combination with TR 451 to cut costs and realize performance benefits.
