COLOMBES CEDEX, France -- Arkema and Toyobo have decided to form a strategic partnership to develop high-temperature polyamides made from renewable resources. Under this collaboration, Arkema and Toyobo will promote a new generation of high-temperature polyamides, with improved technical properties and lower environmental footprint. The new products initially consist of two ranges with melting points around 250°C and 315°C, with a very low moisture pick up and a biobased content up to 70%. Their unique properties make them particularly suitable for highly technical metal replacement applications in consumer electronics and automotive applications, when high-temperature resistance and dimensional stability are requested and where plastics could not be used before. Arkema recently launched Rilsan® HT, a flexible HTPA to replace metal and save costs in highly technical automotive applications.

The packaging manufacturer Artenius PET Packaging Europe (APPE) has announced that it has developed a new design for its PET bottle for wine. This new bottle that will be available under the trade name “Project Santiano”, is a multi-layer bottle using the APPE proprietary active barrier technology namely BindOx. It weighs only 50g while conventional glass bottles weigh 600g or more and its design allows it to accept thermoplastic closure as well as traditional cork closure tanks to a re-designed bottle neck. More than 80% of the wine bottle market is dominated by cork closures. These new bottles will be first introduced in the North-American market.

Royal Plastic Mfg. announced the purchase of one of EOSINT P 800 systems from EOS, a manufacturer of laser-sintering equipment. Royal will use the P 800 to manufacture high-performance thermoplastic products out of EOS' unique PEEK HP3 material. "Laser-sintered EOS PEEK HP3 components have outstanding heat- and corrosion-resistant properties that make them ideal for aerospace," said Bob Evans, Area Sales Manager - Central Region at EOS of North America. "The P 800 purchase is just one more example of how Royal explores and advances new technologies with, and on behalf of, their customers." EOS PEEK HP3 is a high-performance polymer, belonging to the group of polyaryletherketones - with a melt point of 372°C/702°F. It is widely known for its outstanding material properties, including flame and temperature resistance, chemical resistance, high tensile strength, light weight, biocompatibility and sterilizability - properties that make it attractive for aerospace,

On the occasion of the latest ProSweets trade fair in Germany, the Slovakian company Moneta has introduced two new thermoplastic wrap for confectionary that is said to be an interesting alternative to aluminum. These new sweet wraps that have been developed as part of a 18-month industrial project are made from high density polypropylene (HDPP) and comply with the EEC directives regarding direct contact with food. They provide high stiffness and low weight. They can be metalized, transparent or produced with a white pigment. The Yango™ HDPP-O is lighter at 15 microns and can be used with chewy and hard sweets, while the Yango™ HDPP-T is thicker at 17 microns and is applicable to larger size chocolates. According to Moneta, its new packaging are cost effective because they can be heat sealed at 50°C due to their inherent polymer structure and also run at a speed of up to 2000 ppm on standard packaging machines. Furthermore, they allow a shelf life of at least six months for chewy sweet

Alaglas Swimming Pools, an American residential and commercial swimming pools specialist, has announced that it has chosen a “green” thermoset material to produce the structural segments of its composite-based pools. In fact this “green” material is a poly(ethylene terephthalate) modified polyester laminating resin stemming partially (i.e. 28%) from biologically renewable resources and/or recycled materials i.e. the EcoTeck™ H460-EKAD-50 from the American material producer AOC. The new Alaglas composite pools are made using the same manufacturing process and equipment than previous pools made from conventional petrochemical-based polyester. The pool construction begins with a sprayed-on, moisture-resistant gel coat that is backed up with a layer of chopped glass fibres in a Hydropel H010 vinyl ester. Then EcoTek™ H460-EKAG grade is used to wet out the reinforcing glass fiber in three manufacturing steps that create an engineered structural laminate : a spray up of chopped glass fibres
