Rondol has adapted the 10mm Microlab to healthcare specific requirements:

In a preferred embodiment of the invention, the mixture is crosslinked at a temperature of between 150 and 320 °C. The inventive method can be carried out in an internal mixer or, alternatively, in a twin screw extruder or a BUSS®-type co-kneader.

A straw plastic and the preparation method thereof are disclosed, wherein the crops straw with the length of 1.5-2.0mm is dried and mixed with plastic and plastic additive, and then extruded and pelletized with twin screw extruder.

The second extruder (15) can be a single screw or twin screw extruder.

Rondol has adapted the 10mm Microlab to healthcare specific requirements:

Advantageously a mono or twin-screw extruder is used.

The extruder (10) may comprise a single screw extruder, a twin screw extruder, or any other suitable type of extruder.

The method for the continuous production of a composition comprising rubber (20), hydrocarbon resin (22), and solvent (26) provides for the use of a dual-screw extruder (10), for example, a co-rotating dual-screw extruder.

The polymer material (6) is made in an extruder, preferably a double-worm extruder.

A multiple-screw extruder in which paired screws, or segments thereof, contain unequal numbers of flights; and a screw for use in such extruder.

The first screw extruder, the composite roll set, and the second screw extruder are sequentially disposed on one side of a frame.

This screw may be used in any screw press or extruding die.

The first extruder (11) is, desirably, a counter-rotating twin screw extruder.

The extruder is comprised of a screw and a barrel.

The reactor may especially be a co-rotating or counter-rotating single-screw or twin-screw extruder, for example a co-rotating twin-screw extruder.
