Case Study H


• TPV compounder having inconsistent feeding of additives with various bulk densities and different particle sizes
• Blend segregates in the feed hopper
• Labour intensive with premixing and post-blending

PolyAd Services investigation
• Customer would premix additives in a barrel and roll the barrel to mix additives
• Customer must re-blend extrusion to get a homogenous mixture
• Quality problems with incomplete reaction

Solution provided
• Dust free feedable form provided a homogenous extrusion

Value for the customer
• Dust reduction
• Reduced use of labour force for production run
• Improved quality of compound through precise control of additive dosing
• Improved throughput by elimination of post-blending step
