Mix different PP filler masterbatch into PP plastic,thus many properties of PP plastic can be improved,including its physical properties,processing properties and degradation properties.And also reduce the amount of resin used,effec-tively reduce the material cost,and improve economic benefit at the same time.The PP filler masterbatch takes activated calcium carbonate and PP as the main raw material.First adding suitable amount of fertilizer by the recipe,then kneading at a high speed,and tiwn-screw extruded in the end.The main technical indicators:1.melt index 0.05-20g/10min;2.whiteness ≥93;3.moisture content ≤0.3%;4.dispersion:no solid particles,able to be cooperated with all sorts of color.
