Material Versatility in Plastic Extrusion

Standard polymers and technical materials with Bausano

A Complete Overview of Extrusion Materials

Over more than 80 years of activity, Bausano has built deep expertise in processing thermoplastic materials, thanks to applied research, laboratory testing, and rheological analysis conducted in-house. This experience is reflected in the design of plants capable of efficiently and continuously processing a wide range of materials: rigid and plasticized PVC, PE (LD, MD, HD), PP, ABS, PMMA, EVA, TPU, as well as biocomposites and post-consumer regenerated materials. Bausano lines are configured to ensure compatibility with technical additives such as stabilizers, plasticizers, anti-UV agents, lubricants, pigments, and impact modifiers, ensuring correct integration into the polymer matrix. The quality of the final product results from careful management of the thermal profile, residence time, and mechanical shear within the extruder.

Fillers and Loads: Functionality Beyond Volume

Through ongoing process optimization and testing on real materials, Bausano has consolidated its expertise in the extrusion of polymers filled with mineral fillers, natural fibers, and functional additives. These elements — such as calcium carbonate, talc, mica, silica, and glass fiber — are essential for modifying the mechanical, thermal, or acoustic properties of the material. Experience gained in the laboratory makes it possible to design extruders tailored to high-filler-content blends, even with complex rheological behavior. In particular, MD series twin-screw extruders offer optimal control over material flow, applied torque, and filler dispersion, ensuring consistent melt quality and dimensional stability even under critical conditions.

Expertise Applied to Complex Formulations

The historical continuity of Bausano's R&D department has made it possible to develop a rigorous methodology for evaluating formulations, combining applied experience with rheological simulation capabilities. Every line is designed taking into account fundamental parameters such as viscosity, MFI, shear behavior, and the material's thermal sensitivity. The approach is that of genuine technical consulting, where every plant is defined starting from the characteristics of the material to be processed. This includes selecting the screw profile, designing the degassing system, optimizing dosing, and controlling temperature across independent zones. The result is a customized solution, built to ensure efficiency, repeatability, and quality in every production cycle, even with difficult or unstable materials.

Plastic Polymers

Plastic polymers form the basis of every extrusion process and include materials with very different characteristics, such as PVC, PE, PP, ABS, PMMA, and other thermoplastics. The choice of polymer directly influences the final properties of the extruded product, such as chemical resistance, flexibility, insulation, and durability, and requires careful definition of process parameters to ensure stable processability. Over time, Bausano has developed consolidated expertise in managing these materials, with rheological analysis and application testing, to optimize temperatures, screw profiles, and control strategies according to the specific application.

Additives and Fillers

Additives and fillers play a fundamental role in customizing plastic materials, acting on the polymer matrix to improve mechanical, thermal, or surface properties. Substances such as stabilizers, anti-UV agents, lubricants, pigments, and mineral fillers (calcium carbonate, talc, glass fiber) are integrated into the formulation to achieve desired characteristics such as greater rigidity, wear resistance, or improved processability. Bausano's experience in defining the distribution and integration of these components makes it possible to control melt homogeneity and final product performance, even under high-load conditions and advanced technical applications
