Continuous extrusion to cut energy costs and improve quality
By using high precision continuous extrusion with an integral, built-in gear pump, it is possible to move away from old style mills, which have a huge footprint, and generally include plenty of safety hazards. Continuous extrusion removes the need for ramping up production in batches, which simplifies and accelerates preparation; and also separates materials input from production output. Current users report that this improves both control of production and quality.

Structural adhesives composed of epoxy resins and hydrogen bonded styrenic block polymer based TPEs
A wide range of polymer materials with excellent performance and functionality has been developed in recent years to address diverse and complex material applications. Adhesives are one such example of these polymer materials. In general, adhesives are composed of a liquid substance (prepolymer) that is first used to fill in the rough surface of one substrate, and then the adhesive on the substrate is sandwiched by another substrate. Polymerization and crosslinking of the prepolymer in the adhesives are induced by heat or other external stimuli, leading to curing of the adhesives between substrates.
