Abstract: The present invention relates to a method for enhancement of the minimal shear molding process utilizing pellets and/or micropellets produced through controlled extrusional and pelletization processes in combination with nonpowder melt flow rheology that incorporates reduced molding temperature and/or reduced cure time, reduced rotation axis ratios and/or reduced rotation rates. Molding can be uniaxial, biaxial, or multiaxial rotational or oscillatory or both. The molded items produced can be single or multiple layers and can be produced in one or more molding sequences using similar or different chemical compositions.

Abstract: Described herein are extrusion processes to produce hollow pellets. Also disclosed are pelletizer devices that can be used to produce the hollow pellets. The processes and devices make use of an extrusion die having a die orifice and an insert that is placed in the die orifice to produce the hollow pellets.

Abstract: A continuous process wherein a material is melt processed and subsequently pelletized, transported, optionally chemically and/or physically modified, and subsequently optionally defluidized utilizing fluidic processing. The transport fluids and fluid combinations utilize a wide range of process temperatures facilitating enhancement of conditioning, improvement of moisture content, pelletization of hygroscopic, water-sensitive, and water-soluble materials, pelletization of non-polymeric and rheologically non-shear sensitive and marginally shear-sensitive polymeric materials, modification of pellet components through extraction, pelletization of low melting materials, tacky materials, pellet coating, and pellet impregnation otherwise difficult and challenging using conventional technologies.

Abstract: A continuous process wherein polymers or polymeric materials can be subjected to multiple sequential processing systems of differing temperatures and process conditions to synergistically enhance the pelletization and crystallization of those polymers and polymeric formulations, dispersions, and solutions. The multiple sequential processing systems include the processes and equipment for mixing/extrusion, pelletization, multiple transportation processes, crystallization, multiple drying processes, and optional post-processing manipulations of pellets formed. Multiple serial and/or parallel crystallization processing systems are disclosed.

Abstract: A combination of surface treatments that synergistically provides abrasion, erosion, corrosion, and wear resistance simultaneously conferring a minimal stick surface that can effectively eliminate problematic obstruction of passageways and unwanted stricture, accumulation, clumping, and agglomeration of pellets and micropellets during the pelletization, transport, drying, crystallization, and post-processing of polymeric and related materials.
