Polyolefins are synthetic resins, polymeric chains, primarily derived from petroleum but also from sustainable sources such as sugar cane, polypropylene (PP) and polyethylene (PE), and high-density polyethylene (HDPE). Polyolefins are found in many common items, including rigid and flexible packaging, building and construction materials, moldings, flame retardant products and agricultural films. Polyethylene (PE) is the most widely used polyolefin and the most versatile based on its densities and properties.
The Farrel Continuous Mixer ensures consistent reliability and performance for producing high volumes of PP, HDPE, linear low-density polyethylene (LLDPE) bimodal resins and other polyolefins. The high volume of these operating “trains” requires extremely reliable pelletizing and finish solutions and low operating costs provided by continuous mixing technology.
Farrel is qualified in the post reactor product finishing of HDPE & LLDPE including bimodal resins which have been produced under Univation Technologies Unipol™ process.
The Farrel ADVEX™ System is specifically designed for efficient post-reactor finishing of polyolefins and excels at the processing of LLDPE and HDPE resins where processing temperatures and pressures are process limitations.
The ADVEX™ System is comprised of a Farrel Continuous Mixer, Melt Pump and Pelletizer combined to form an advanced multi-stage polymer compounding system, post reactor with the capability for the inline adjustment of rheological properties and addition of post reactor additives. Each ADVEX™ System is custom designed.
Utilizing the Farrel Continuous Mixer, high amounts of mechanical shear can be applied across a wide range of product viscosities efficiently with control of the shear force and specific energy applied to the polymer which maintains processing temperature and reduces specific energy requirements.
Polyolefin compounds are found in many industries and applications including:
