Thin-walled LEDs for mobile phones

he Japanese plastic converter Nissei Industries Ltd. has produced the thinnest low-profile side view light-emitting diodes (LEDs) specially designed for thin-profile mobile phones. This ultra-thin LEDs are 0.4mm high and are made from a 22% mineral filled, light-stabilized, high-reflectivity polyphthalamide (PPA) material supplied by the Belgian material producer Solvay Advanced Polymers i.e. Amodel™ A-4422 LS WH118. This grade allows to fill very thin walls and runs in high-cavity molds up to 264 cavities. It has a fast crystallization rate and offers higher flow, faster cycles, lower flash and greater overall performance than conventional glass fiber reinforced polyamide-9T materials. The PPA ultra-thin LED reflector cups are injection molded onto the lead frame by Nissei Industries and supplied to a Taiwanese packaging company that produces LEDs for the mobile phone industry.

Automotive interiors combining natural fiber aesthetic and Class A finish

The innovative automotive interiors specialist Johnson Controls Interiors (JCI) has developed a concept car for the small-vehicle market that was unveiled on the occasion of the 2009 North American International Auto Show. This concept vehicle, namely ‘re3’ (for Rethink the interior through innovative engineering, Renew with sustainable solutions, Respond by generating consumer appeal) is both fuel-efficient and eco-friendly by design. It features the use of visible natural fibers in the vehicle interior thanks to the so-called “Exposed Natural Material” technology, which complies with the stringent requirement for Class A finishes: a wood fiber mat with acrylic resin binder i.e. Fibrowood™ material or a moldable mat made of polypropylene (PP) and natural fibers that can be formed and covered in a one-step process i.e. EcoCor™ have been used to produce the instrument and door panels, the Class A surface being obtained by applying a thin, transparent film onto the panels. This technology offers authentic and natural aesthetics for the interior while providing up to 30% weight saving compared with conventional laminated solutions.

Now chain criminals with thermoplastic vulcanized hand cuffs!

To ease up the process of maintaining law and order, law-enforcement agencies can now use ‘Cobra cuffs’ while doing mass arrests or controlling the crowd on a large scale. Milspec, an Asheville NC-based thermoplastic vulcanizates (TPV) manufacturer has introduced these police cuffs, that are made of Sarlink 3100 with 45 shore D grade. Because this TPV shows neutral colorability, Cobra cuffs can be made available in various colors choices of: black, orange, yellow, red, pink, and blue. This also makes color coding possible, thus enhancing safety and processing detainees according to criminal charges.

This grade features high flexural fatigue endurance, heat resistance, impact strength, 250 pounds of tensile strength and good abrasion strength. Sarlink combines the performance characteristics of thermoset rubber, with the ease of plastic processing. Sarlink is a thermoplastic vulcanisate based on dynamically vulcanized ethylene propylene diene monomer (EPDM) rubber particles dispersed in a polypropylene (PP) matrix. Sarlink TPVs are also used in various other applications, such as wires and cables, pipe seals and under the hood.

Arkema and Toyobo to Start Alliance on High Temperature Biobased Polyamides

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.

New PET bottle design for wine

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.
