The main objective is to produce powdery free-flowing rubber/filler batches (powder rubber, PR) which allow the introduction of a continuous compounding process in the rubber industry in the medium- to long-term future.
1 and 3) and render continuous compounding processes possible, special attention is to be focused on the viscosity of the NR latex used in the powder rubber.
The extruder is presently used for industrial process studies and has been slated specifically for a new study on the
continuous compounding of robber at the German Institute for Rubber Technology.
In considering a continuous compounding system for the silicone sealant, these key elements can be redefined in terms of unit operations.
Burbank, "Continuous compounding technology for the rubber industry," The Northwest Regional Rubber and Plastics Exposition, September 21-22, 1994.
The principle applies equally well to
continuous compounding as it does to batch.
Up to this point, the energy costs associated with converting rubber in bale form into particles or granules for feed to a continuous mixer have not been justified by process or quality improvements gained through continuous compounding.
While it is our conviction that continuous compounding will play an increasing role in rubber compounding in the coming years as more polymers become available in crumb form and solution, addition of structural modifiers becomes more prevalent, the practical reality is that the vast majority of today's polymers remain available only in bale form, or in chips too large for small volume continuous compounding.
arm of the Italian manufacturer of batch and
continuous compounding machinery, has taken several steps in the past year to increase its ability to serve North American plastics processors.
This is a
continuous compounding system, as opposed to a batch compounding system.
