Corotating, twin-screw
compounding extruders and pelletizing systems; twin-screw
compounding with direct in-line sheeting of filled and reinforced plastics; single- and twin-screw extruders for devolatilization and specialty applications; and single-screw profile extrusion systems from commingled reclaim.
Because
compounding can make your money grow substantially over a relatively short period of time.
Twin-screw corotating, intermeshing extruders from 25 to 324 mm with OD/ID ratios of 1.24, 1.46, 1.55, and 1.74 for
compounding, reinforcing, filling and masterbatch production.
If one adds the above difficulties and frustrations to an industry where the rubber mixing and
compounding process related experience and knowledge are fast approaching retirement age and then considers the difficulties associated with maintaining product uniformity, the need for a better understanding of the probable causes becomes even more important.
It color coats individual pellets at a cost 20% to 50% less than typical
compounding. The process is currently focused on TPVs.
From a
compounding perspective, compounds which are designed to contain an optimal level of a high structure, low surface area, carbon black usually imparts a good surface appearance to their extrudates (ref.
Lascak recalls visits to the
compounding plant in the early days: "The PVC started as junk.
In the last 20 years, there has been a trend in the rubber industry to use pre-weighed blends of many of the powdered
compounding ingredients in special dispersible poly bags, prepared either in-house or from an outside supplier, in order to improve productivity and quality while reducing dust in the factory.
Twin-screw extruders available in designs, which include the 42-mm parallel counterrotating high-shear miniature
compounding design with output rates to 3.6 kg/ hr; conical model in counter or corotating 42 mm, 17:1 L/D ratio for extrusion rates to 20 kg/hr; and 25-mm segmented twin-screw extruder with L/D ratios from 16:1 to 48:1.
With two facilities to better service you, Biltrite Industries has committed itself to attaining the highest standards in its custom rubber mixing and
compounding business.
Manufactures twin-screw
compounding extruders and replacement parts, along with servicing.
Offers a self-contained
compounding and blending system for PVC.
The aim was to apply this technology within a direct extrusion concept, a combination of continuous
compounding and subsequent profile extrusion.
Corotating, twin-screw
compounding extruders and pelletizing systems; twin-screw
compounding with direct in-line sheeting of filled and reinforced plastics; single- and twin-screw extruder for devolatilization and specialty applicatins; and single-screw profile extrusion systems from commingled reclaim.
In elastomer
compounding, excess heat generated by the shear forces of the counter-rotating rolls is removed by cooling the rolls to promote good handling and reduce sticking.
