decorative products for plastic and rubber applications. Part of Sun’s SunPad range of inks, the new ink is suitable for use on a range of substrates and is free from BPA, cyclohexanone, butyl glycolate and aromatic hydrocarbons, making it suitable for use in food, drink and medical applications. The company says the ink is compliant with RoHS, REACH and EuPIA standards and meets the EU Toy Safety Directive DIN EN ISO 71-3:2013, as well as USP Class VI – Certificate for medical applications. It can be applied to a wide range of thermoplastics,

including hard PVC, PMMA, PS and PET. Applications include bottle caps, medical syringes, toys, mobile phones and many more. The company’s stand will also show the full range of


inks for applications in automotive, technical, plastics decoration, pad printing, and functional print and printed electronics, including the SunHytek, SunCarte and SunPoly products. ❙ www.sunchemical.com


Teknor Apex will introduce a new thermoplastic vulcanisate (TPV) with improved lubricity for production of injection moulded parts such as pipe seals. According to the company, the new Sarlink 9156-02


grade provides near identical physical properties to its current 9156B product, which it describes as its “workhorse compound” for pipe seals for non-pressure and drainage pipes, but exhibits a coefficient of friction only 16% as high. “The substantially greater lubricity of new Sarlink 9156-02 is a big advantage for inserting the seals into the fittings—a mechanical process in which lubrication increases speed and helps to prevent rejects,” says Stef Hordijk, General Sales Manager for the Thermoplastic Elastomer Division of Teknor Apex. “Fittings with lubricated seals also facilitate pipe insertion, which is done by hand at the construction site.” Compared to traditional rubber, both grades offer

better retention of sealing force and improved stress relaxation at elevated temperature. Both can also be processed by two-component moulding with PP or other TPVs. Teknor Apex says the new grade will be available globally. ❙ www.teknorapex.com

provide glass fibre contents of between 30 and 60 % and are available with a granulate length of 6 - 12 mm. The company will also show a new flame retarded short glass fibre reinforced partially aromatic PA grade – Terez HT 200 H G30 FR40- that offers a UL94 V-0 rating and is targeted at metal replacement applica- tions where exposure to high temperatures and water is likely. The new grade also shows good tribological performance, according to the company. Other novel products include a PMMA-based Terez


grade with a special coloration technology for LED applications. The new grade is said to display very good impact performance and light scattering and allows customers to save cost by eliminating LED tapes. The company will also introduce three new POM products from principal Polyplastics. The Duracon M90-57, M270-57 and EX-09 grades carry full food contact approval. ❙ www.terhell.de


Topas Advanced Polymers will display its cyclic olefin copolymers (COC) for applications in healthcare, packaging, optics and electronics. In healthcare, the company says that Topas COC has been identified as a highly effective alternative to Barex polyacrylonitrile (PAN) in a wide range of pharmaceutical packages such as medicinal pouches and patches and other applica- tions such as food and cosmetics that require strong chemical resistance and adsorption. In diagnostic products such as microfluidics and microplates, Topas COC is claimed to offer good chemical resistance and UV transparency compared to competitive thermoplas- tics like polystyrene and polypropylene, while being easier to manufacture in volume via simple injection moulding compared to alternatives like glass and silicones. According to the company, Topas


COC’s performance is closer to glass in optical applications than any other polymer. The high-clarity, high-flow polymer is used in light guides, automo- tive heads-up displays (HUDs), sensor lenses, and touch screens (ITO film). In


electronic applications, COC’s heat resist- ance, moisture insensitivity, light weight, and dielectric performance make it attractive for advanced electronic design in mobile device antennas, as well as high-performance capacitors, says the company. ❙ www.topas.com
