Removable Agitator Ribbon Ensures Pure Additive Blends
A polymer additives manufacturer installs a ribbon blender to allow quick product changeovers and increased capacity.
Chemtura Corp., Middlebury, Conn., manufactures preblended polymer additives that are widely used in the plastics industry in PVCs, polyolefins, and rubber compounds. These additives prevent plastic degradation caused by high heat or UV radiation exposure, protecting such end products as plastics bags, floor coverings, vinyl siding, automobile dashboards, and disposable diapers. To make the additives, the company blends several powder ingredients together with a very tight composition specification. After blending, the additives, also known as processing aids or polymer stabilizers, are then further processed into a pellet or other compacted product and are ready to be shipped to a customer.
