repeatedly pointed out the need for E-TPEs with superior performance characteris- tics and the need to lower overall systems cost. We believe that our Ny-Flex grades deliver incredible value to the customer compared to other E-TPEs.” According to the company, Ny-Flex E-TPE
grades deliver a broad range of benefits including good flexibility at low temperature, retention of properties to elevated temperature, as well as toughness and resilience. They also provide high creep resistance, strong resistance to flex fatigue, good abrasion resistance, and resistance to greases, oils and solvents. Ny-Flex E-TPEs also have a low specific gravity compared to TPUs and are easily processed. Actega DS has developed a customised TPE handle material for butcher’s knives for use in shops, abattoirs and industrial meat processing. The application places high demands on the material in terms of grip and durability while the material has to comply with all regulations applying to items coming into contact with food. The company says its SoftEst TPE materials meet these requirements and are available in ultra-transparent, translucent and natural-coloured versions in Shore hardnesses ranging from A-20 to A-85. All of the materials are food-safe in accordance with EU 10/2011 and FDA regulations. The company notes a number of additional benefits of the SoftEst TPEs in this particular application area. Antimicrobial properties can be incorporated during the compounding process to impart a germ-resistant effect that is not affected by external impacts, such as scratches, excessive use or wear. In addition, masterbatches added during injection moulding can make the TPE detectable to x-rays and other devices to ensure safety from residue in a hygienic environment.
Durable TPEs Kraiburg TPE has introduced a new compound to its Thermolast K UV/LD/b series, designed to meet the needs of demanding outdoor applications for building and construction, electrical engineering and electronics, as well as automotive. In addition to high UV resistance, the company says the new grade combines good mechanical and thermal properties with adhesion to polyolefins and a good

surface finish. Among the first applications is for production of an over-moulded boot at the interface of co-axial cables and metal connectors used in outdoor installations at cell towers. “There is a growing demand for high performance thermoplastic elastomers in industrial outdoor applications,” says Kevin Gase, Director Sales & Marketing Americas for Kraiburg TPE. In addition to good thermal and
UV resistance, the new TPE compound provides a hardness of 35 Shore D - equivalent to 90 Shore A – which is at the top of Kraiburg TPE’s existing range of Thermolast K UV/LD/b product range. At the same time, the material delivers the flexibility for the cable boots to ensure proper strain relief. Kraiburg TPE has also launched silky-smooth TPE compounds for consumer electronics. The VS/ AD/HM series is claimed to offer silky, satin-smooth surfaces that feature high scratch and abrasion resistance, good durability and resistance against chemicals, such as sebum oil, creams and common household detergents. The series is designed for consumer electronics applications. The VS/AD/HM series has been specially developed for applica- tions that require surface effects along with adhesion to polar thermoplastic compounds such as PC, ABS, PC/ABS, PU, ASA, SAN, PA12 and PA6. Available in natural colour and black, the com- pounds also have good processing properties. Example applications include controllers for games consoles, remote controls and headphones, toys, protective covers for mobile phones, tablets and cosmetics packaging. Kraiburg TPE recently increased TPE production capacities at its three manufacturing sites in Germany, US and Malaysia through the addition of new compounding lines. In the US, the newly-built Kraiburg TPE plant at Buford in Georgia has seen an annual capacity increase from 6,000 to 10,000 metrics tons. Also in the US, Polymax TPE has increased compounding capacity at its Waukegan, Illinois facility. Additional annual capacity of 3,630 tonnes has been added through a new compound- ing line to expand manufacturing of its line of TPEs, including SEBS, SBS, TPOs and alloy products.
