TPE breathable films
TPE breathable films Multiple compounds of the firm's Terraloy bioplastic with Arkema's Pebax thermoplastic elastomer are said to make possible a range of breathable films for housewrap. Compounds are comprised of a blend of Pebax engineering grade TPE with Terraloy bioplastics, which are derived from plant-based, renewable resources. By varying the Terraloy biopolymer content, the firm has developed multiple grades of the blend, which can be used to produce films with various levels of moisture permeability. Such films can be bonded with nonwoven fabrics to form housewraps that allow moisture vapor to escape from homes, preventing mold and mildew, yet remain waterproof. As TPEs, Pebax products are said to combine the advantages of thermoplastics with the elasticity of rubber, and are said to provide exceptional performance.

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.

Coagent additives
Natrochem and Arkema's Sartomer Division have partnered with this company which provides additives that can help enhance physical properties of peroxide-cured elastomer compounds. Natrochem works closely with the Sartomer team which provides liquid coagents to create the Natrochem Dry Liquid Concentrates (DLC) of those liquid coagents. Use of peroxides has been proven to enhance heat aging performance, but by themselves fail to maintain the dynamic properties of a sulfur-cured compound. However, with the addition of coagents to peroxide curing, it has been demonstrated in numerous applications that dynamic properties such as compression set, hardness, modulus, elongation and tensile strength can be maintained or improved beyond sulfur vulcanization. Moreover, coagent addition to a peroxide cured elastomer is said to improve the rate of cure, the state of cure, and heat and chemical resistance. Additionally, coagent addition can potentially reduce the peroxide initiator requirement. Coagents that increase both the rate and state of cure are referred to as Type I. The second class of coagents, referred to as Type II, typically generates fewer reactive radicals through hydrogen abstraction contributing only to the state of cure. Sartomer recently introduced a new liquid coagent, SR 523, which has both methacrylate and allyl functionality.
