Custom engineered TPEs
Custom high-flow materials formulated by the company are said to have benefited the automotive manufacturing process. The development of these materials allows the TPE to fill the mold cavity with even pressure, thus permitting for consistent gloss on the show surface of the part. The firm's TPEs are said to typically help increase the molder's profitability because they yield reduced cycle time, reduced scrap, reduced off-gassing and are easier to process. In the same manner, high flow TPEs generally process at a lower temperature than typical olefin-based TPV materials. This is said to allow for quicker molding cycles, as the material does not need to cool as much prior to part ejection.

Polymers for semi-structural applications
Polymers for semi-structural applications Enlite structural polymers use technologies that can replace existing materials such as steel and aluminum with lighter, globally available, cost-efficient solutions. The company is said to be exploring further solutions to offer automotive manufacturers a broad range of Enlite products and global semi-structural solutions in the near future and for years to come. Enlite LGF-PP provides a lightweight alternative to help customers meet market regulations regarding vehicle weight. With a 60% glass concentrate system, which is diluted with neat polypropylene, customers have the flexibility to achieve the direct proportion of glass they need. One example offered by the company is the development of the lift-gate and front-end module of the new Renault Espace, which was designed with the firm's LGF-PP polymers. This innovation is part of a long-term collaboration between Renault and the company, which began with a real serial life solution in the Renault Clio. Like Enlite LGF-PP, Enlite GF alloys offer lightweight optimization and customer flexibility. This product provides a bridge between the glass-filled polypropylene solutions of today and the enhanced carbon fiber solutions of the future. Enlite GF alloys tackle specific areas in which process constraints are difficult to overcome. For example, when the design of the part necessitates thick walls to meet stiffness requirements, or the elimination of steel reinforcements, GF alloys provide an optimal solution. The first product designed in the GF alloys range is the GF-ABS alloy, which is a glass concentrate diluted with ABS. The firm's technology is used in industries such as rubber goods and tires, automotive and more.

Innovations in rubber carbon blacks provided
Innovation and product development for both the manufactured rubber goods (MRG) and tire markets, as well as customer service are provided by this company. Clean, high-structure grades are offered for Class A extrusion finish, and a low-structure grade is available for very low conductivity to prevent electro-chemical degradation and electro-chemical corrosion. For the tire market, the company offers both narrow and broad aggregate size distribution carbon blacks for improved abrasion resistance and low rolling resistance, respectively. Four clean grades of carbon black have been developed specifically for profile extrusions. LS 18, a low conductivity grade, features large particle size and a relatively low aggregate structure level, and reduces the electrical conductivity of parts. The combination of particle size and structure of LS 18 is said to allow the compounder to develop compounds which will extrude very well with little die swell. HS 22, with low specific surface area and high structure, is said to provide rubber compounds with excellent extrudability, and extruded articles with very smooth surfaces. Given its specific reinforcing behavior, HS 22 allows high filler loadings and high extrusion speed, which are said to result in more economical MRG production. HS 25, with very low surface area and high structure, imparts low compound viscosity and low die-swell, both of which are essential for high-speed extrusion processes. Thanks to its extremely low sieve residue, HS 25 is said to be an outstanding carbon black for such extrudates as profiles requiring excellent surface quality and thin-walled hoses. HS 45 is similar in properties, benefits and applications to HS 25, but has a higher specific surface area. Good reinforcement, good dispersion and low die swell are said to make it particularly suitable for extruded products. Carbon blacks along the entire aggregate distribution spectrum have been developed by the firm to respond to varying market requirements. The company's rubber carbon blacks with narrower aggregate size distribution are said to improve abrasion resistance, and thus tire tread durability, for longer life. The firm's Innovation Team works with its existing technical marketing teams to better anticipate and respond to customer requirements and market demand.

QC for black rubber
Rhenowave is a concept for controlling the quality of rubber compounds. The compounds are analyzed during extrusion (for example, during straining or shaping) in a pulse transmission process with the help of ultrasound waves. Nanoscale fillers such as carbon black and silica have particularly good damping properties for soundwaves in the range of 1 MHz to 20 MHz, so that the filler content can be determined with a precision of up to 1 phr. Unlike with many other analytical methods that use electromagnetic waves, carbon black does not disturb this process. As a result, even black compounds can be volumetrically analyzed. Owing to the sound scattering, large inhomogeneities (>10 m) can also be determined.
