ProTec Polymer Processing GmbH, headquartered in Bensheim, Germany, is an internationally operational systems supplier to the plastics industry. We build plants and systems for material handling, plastic finishing, recycling and complete plants for producing long fibre thermoplastics (LFT pultrusion plants). Our products and solutions successfully support production by plastics manufacturers and plastics processors in the fields of injection moulding, extrusion and blow moulding. Our work spectrum is widely diversified and goes far beyond developing and implementing individual solutions for our customers. We think of you as our partners. We are by your side, advising you from an initial assessment of needs, through planning and implementing processing steps, designing and calculating the processes used right up to delivering the devices and plants. We install them, commission them and then train your employees to use the technology.

ProTec designs and supplies innovative solid-state polymer post-condensation lines and complete PET bottle flake recycling lines. The batch tumble reactor which combines homogeneous mixing with short processing times is the keystone of the line. The IV value (intrinsic viscosity as a yardstick for molar mass) of polyesters (PET, PBT, PTT etc.) and of polyamides (PA6, PA66 etc.) can be purposefully increased by precise control of temperature, vacuum and processing time, with or without defined addition of auxiliaries.

The SOMOS® RDF dryer is used for drying hygroscopic polymer pellets. It consists of compact RDF modules which can be flexibly combined, are capable of autonomous operation and have drying capacities of 10 kg/h to 250 kg/h per module. The modules are available in 7 sizes with a volume of between 30 l and 600 l and a drying are volume between 10 m3 and 180 m3, each one being individually controllable by its own controller. Alternatively, when interconnected, they can be controlled using a common operator control unit. Each module has an integrated air generator, so ruling out complete failure, as may occur with a centrally supplied drying system.

Modular SOMOS® RDC stationary drying systems are suitable for efficiently drying virtually any kind of hygroscopic polymer pellets and regrind. The material is dried with heated drying air, optimum air distribution in the material being dried ensuring uniformly good drying results. ProTec designs and supplies RDC drying systems made to measure for all polymer processing processes. Material throughputs meet demand from individual machines right up to a plant's entire installed base of machinery.

The Batchmix 50 to 3000 models cover gravimetric dosing applications with throughputs of 5 to 3,000 kg/h. Usable for pellets and regrinds. Solutions for special applications are available. Depending on size, the machines can handle between 4 and 12 different materials and option packages are available to extend their functionality. The unique mixing technology used maximizes the dosing accuracy and uniformity of the mixed product.
