Processing Aids
Processing aids are materials that are added to improve the processability of polymeric compounds. Improved processability lowers the cost and improves the quality of the polymer. With the help of processing aids, extrusions run thinner and faster and molding cycles shorten . PVC's, polyolefins, nylons and other engineering plastics are known to benefit the most from the addition of processing aids. Most used processing aids are styrenes, acrylics, calcium carbonates, lubricants, silicone oils etc.
