Steam-resistant silicone
Elastosil LR 3020/60 liquid silicone rubber cures to form a steam-resistant and hydrolytically stable elastomer. The fast-curing rubber is said to be suitable for highly automated injection molding, and therefore enables cost-effective, large-scale production of molded seals and other products that need to permanently or regularly withstand hot water or steam, according to the company. Elastosil LR 3020/60 is a two-component liquid silicone rubber compound which is optimized for injection molding and vulcanizes rapidly via a platinum-catalyzed addition reaction. A special feature is said to be its high steam resistance once the silicone is cured. Standard silicone elastomers can only withstand superheated steam for short periods, making it suitable for such applications to a very limited extent. The reason for this is that silicone elastomers generally hydrolyze under these conditions, i.e., are chemically decomposed by water. This reduces their elastic recovery under pressure, and as a result, the seal leaks. This cannot happen with the Elastosil LR 3020/60 grade. It is said to be largely resistant to hydrolysis and even retains its elasticiity in persistent contact with superheated steam, according to the manufacturer.

Tire striping products
Tire striping products From unique rubber compounds to varying tread patterns, tire producers are said to focus on a number of areas on the tire to set themselves apart and perfect the look of the finished tire. Although not a primary focus of tire designers, the brightly colored identification marks around the tread play a key role in tire building, as well as the aesthetics of the finished product. Vibrant, long-lasting stripes have been developed and commercialized by this company by optimizing the ink formulation and application equipment for tire makers. Tire makers are said to have found that some consumers will correlate a fresh new tire with the vibrancy and completeness of the tread stripe, according to the company. Regardless of whether a tire has passed inspection, it can provoke the inclination that it lacks quality if the stripe appears faded, has been removed or contains any imperfections, according to the company. The firm is said to address this consumer concern and meet tire companies' practical requirements for tread striping with an industry-proven line of inks which remain vibrant for an extended period of time, adhere to the rubber compound, cure under a variety of drying conditions and meet EPA restrictions on solvents and VOCs. The ink chemistry is a unique formulation that is offered in two water-based versions, based on viscosity. Depending on the application equipment being used to apply the stripe, the company determines the appropriate ink system for the tire maker. Chemistry is not the only component of a perfect tire stripe; the application equipment is also critical to stripe aesthetics and lifecycle. This is the reasoning behind the companys newly formed team of engineers who design and install customized equipment for individual tire facilities. The company offers three base striping systems, and each system is custom-designed to meet the needs of the individual production facility, whether engineering for the degree of automation required or number of stripes/colors applied.

High-temperature FFKM solutions for oil recovery
To meet the challenges of operating in high-pressure, high-temperature conditions, oil and gas exploration and production companies are increasingly using enhanced oil recovery techniques to extract as much of the remaining 60% to 80% residual oil out of the reservoir as is economically feasible. These newer production methods typically utilize gas, thermal (steam) or chemical injection to extend the productive life of a reservoir. Despite the popularity of these methods, each is known to place significant additional strains on the mechanical seals, pump seals, o-rings, gaskets, t-seals and packings that are the workhorses of downhole oil and gas recovery applications. Exposure to high temperatures can cause these seals to lose their elasticity, making them hard, brittle and susceptible to outgassing. Contact with harsh chemicals and solvents can cause some elastomeric seals to swell, potentially leading to their rupture and the contamination of both the process and outside environments. To meet the challenges of operating in these harsh environments, the company has developed the Aflas FFKM series PM-1100 and PM-3000 as superior resins for fabricating o-rings, gaskets and other oilfield seals and packings. Components made from these peroxide-curable perfluoroelastomers (FFKMs) are said to provide outstanding resistance to the high temperatures, pressures and increasingly aggressive chemicals employed in oil and gas recovery. The chemical structure of Aflas PM-1100 and PM-3000 is derived from tetrafluoroethylene and perfluoroalkyl vinyl ether, which is said to offer superior resistance to chemicals, oils and solvents. Because components formulated with Aflas PM-1100 and PM-3000 last longer in critical applications, they are said to help to reduce downtime and improve production. Both of these Aflas FFKM series resins can be compounded to be highly resistant to rapid gas decompression. Aflas PM-1100 imparts a continuous service temperature of 230C, with peak excursion exposure to 250C. Aflas PM-3000 imparts a continuous service temperature of 250C, with peak excursion exposure to 270C. The company is also developing an ultra high-temperature peroxide-curable FFKM, CP-4000, which will impart a service temperature between 280-330C.

Lubricated TPVs
Lubricated TPVs A thermoplastic vulcanizate elastomer for pipe seals is said to exhibit the same processing and performance advantages over thermoset rubber as a well-established TPV, while providing enhanced lubricity for faster insertion of seals and more error-free assembly, according to the company. For use in seals for non-pressure water and drain pipe, Sarlink 9156-02 is said to provide physical properties nearly identical to those of Sarlink 9156B, a workhorse compound for pipe seals; but as a lubricated compound it is said to exhibit a coefficient of friction that is only 16% as high. The substanially greater lubricity of Sarlink 9156-02 is said to be a big advantage for inserting the seals into the fittings, a mechanical process in which lubrication increases speed and helps to prevent rejects, according to the manufacturer.

Liquid silicone rubber
A novel liquid silicone rubber grade is said to achieve an extremely high 90 durometer A hardness after curing. Elastosil LR 3003/90 is processed by injection molding and cures rapidly to form an exceptionally hard and high-modulus elastomer. This is said to make the material ideal for cost-effective, large-scale production of dimensionally stable silicone products. It can also be used as the hard component in hard/soft combinations. The Elastosil LR 3003 series is already said to offer a selection of liquid silicone rubber grades with durometer A hardness values ranging from 3 to 85. With the Elastosil LR 3003/90, the company is said to present a product that outperforms all other liquid silicone rubber in hardness and rigidity. The cured material almost falls into the transition zone between an elastomer and a thermoset. On the one hand, the cured rubber still possesses a certain degree of elasticity, while on the other hand, it features very high dimensional stability for an elastomer, according to the company. It has a hardness of 90 durometer A or, measured with a durometer D tester, 33 durometer D. Alongside this hardness, which was previously unattained with liquid silicone rubber, Elastosil LR 3003/90 is said to feature an exceptionally high modulus. It is thus more rigid than the cured products of all previous liquid silicone rubber grades, according to the manufacturer.
