Polyolefins

This group of polymers forms the backbone of the plastics industry, offering a wide range of grades and a variety of compounding processes to tailor materials to market needs.

Processing tasks may include the incorporation of additives and mineral fillers, fiber reinforcement, or the blending of different polymers.

Engineering Plastics

KraussMaffei Extrusion combines extensive experience with state-of-the-art technology to deliver superior product quality and consistency.

Whether compounding PPA, PC/ABS, or high-performance polymers such as PEEK and PPS – our twin-screw extruders ensure high throughput, gentle processing, and precise process control.

From raw material handling to pelletizing, we provide customized complete solutions for diverse material requirements.

Masterbatch and highly-filled compounds

Black, white, green, blue, red … or UV-HALS? Masterbatches (highly concentrated, pre-dispersed pigments, fillers, and additives) are essential for the plastics industry.

They allow easy material adjustments, are stabilized, and ready for use. We offer standard and custom systems for pre-mix, split-feed, reactive compounds, and effect pigments, optimized for efficiency, cleaning, and flexible recipe changes.

TPE

The combination of thermoplastic processability with the elastomeric properties of rubber makes TPEs highly sought after. Our twin-screw extruders mix TPS and TPO, incorporate oils, fillers, and additives, dynamically vulcanize TPVs, or synthesize linear TPUs.

Building on our rubber processing expertise, KraussMaffei Extrusion integrates extruders and gear pumps for direct material feeding.

Bioplastics

Bioplastics include both bio-based and biodegradable materials, and KraussMaffei Extrusion has extensive experience in both. Our machines handle PLA/Lignin compounds, wood-plastic composites, and biodegradable polyesters like PBAT and PBS.

Sensitive to moisture and temperature, these materials benefit from our BluePower series combined with pelletizing expertise, offering turnkey solutions for bioplastics projects.

Cable compounds

Polymers are indispensable, and ZE BluePower extruders cover a wide range of applications. Soft PVC and HFFR compounds benefit from gentle processing, while fluoropolymers are supported by versatile construction materials.

XLPE can be processed for peroxide crosslinking and silane grafting, and semiconductive carbon-black compounds for medium-voltage applications are also established uses of our extrusion systems.

Reactive Extrusion: TPU

As pioneers in the plastics industry, there are almost no applications that are too exotic for us to tackle. With decades of experience, there is a chance we have already worked on a project like yours.

PVC Pelletizing

PVC dry blends are usually supplied as powders, but for use on single-screw extruders or injection molding machines, pellets are often more advantageous.

KraussMaffei Extrusion offers customized solutions for rigid, chlorinated, and soft PVC. By combining proven counter-rotating twin-screw technology with a specially developed pelletizing head, a highly efficient complete solution is created.
