Currently evaulating the cost benefit of purchasing PVC in powder form versus pelletized.

Flexible, semi rigid, and rigid PVC.

Equipment requirements for optimum output and quality.

Is twin screw extrusion required even for the flexible material?

Would a vented single screw extruder work?
What are the down falls in feeding powder and possible contaminents?

Any information or reference information would be apprectiated.

Before you even start, why don't you first state your annual use. How many product codes do you have Benchmark's like these are needed.

Usuage is approxoximately 2 - 2.5 million pounds annually between 4 products. 70% would be flexible with 30 % rigid
