Lab
Services:
• Compounding:
o Batch Mixer:
We have the 10 gram in, 5 gram extruded out SFEM-BM-1000-4.
o Four Compounding Extruders:
Compounding capability from 125 times better than a
typical
single screw to 1,000 times better than a single screw. The extruders range in
outputs from
30 grams per hour on our RCP-0375 to about 30 pounds per hour on our
Taskmaster 1,000 with
up to 3 vents for degassing. L/D’s range from 2 mixer 24/1 L/D to 4 mixer 50/1
L/D.
• Direct
Compounding: Often, melt mix compounding is possible while we make
products such as film,
sheet, etc.
• Pelletizing:
There are three pelletizers in the lab, RCP 2.0 with dual drives (in
bench and floor model)
and an RCP 1.0 Micro-pelletizer.
