...nsional stability. The high-gloss surface required for metalizing is retained, thanks to a combination of optimized mold temperature (around 95°C) and very fast injection. DuPont also made its Shine-E Rynite PET, first announced at NPE 2003, available for sampling this July. This proprietary non-glass-reinforced PET is said to offer both high gloss and on-line E-coat paintability for auto exterior body panels. It is now also being evaluated for heat-resistant appliance parts such as oven door ha...

...sorption and reflection of the laser beam in the top layer. Proven Laser Weldability For the data and weld parameters listed in Table 1, Fig. 4 shows the weld temperature (the first temperature on the y-axis, here 348°C), calculated for the Rynite PET standard grade (melt temperature = 265°C, high laser transparency of the top layer), and the melt depth (the last x value, here 0.011mm). The laser beam, with its radius of 2.5mm at a speed of 6000mm/min, acts on every point in the middle of the ...

...o minimise warping to ensure that the module parts all fitted perfectly together. The issue of which material to use was to be decided by Moldflow studies that would take account of the high stress involved. Two raw materials were up for selection: Rynite SST 35 (manufacturer: DuPont) and Valox 830 (manufacturer: GE). The crucial questions were how do the glass fibres align themselves, how much warping occurs and what quality of surface is feasible with the materials (30 % glass fibre content). ...

Kunststoffe international, 2007-05-14, Big Opportunity for the Plastics Industry
Big Opportunity for the Plastics Industry Photovoltaics Throughout the world photovoltaics is booming. Growth rates have usually been two-digit over recent years. Plastics enterprises also profit from this, since a solar panel is not only made of silicon. It rather employs a variety of materials for backsheets, frontsheets, encapsulations and junction boxes. This seminal sector thus provides excellent chances of growth, also for the plastics sector. Hilde Roekens, Axel Beyer By the end of ...

...ents for the electronic consumer goods sector are completely different. Here materials without brominated flame retardants are needed. The answer lies in the halogen-free, flame-retardant, UL94 V0-approved grades Zytel HTN FR52G30NH and Rynite RE19041. The first Rynite parts are now being used in printers, lamp sockets and electrical/electronic components requiring a glow wire ignition temperature of 775°C according to IEC 60335. Two new grades, ZE55201 and ZE55801, have been added to the Zenite...

...current resistance exceed those of standard types. The product additionally provides high resistance to chemicals, moisture and heat. The material is ideally suitable for use in lead-free SMT soldering processes. A new PET flameproofed with halogen, Rynite RE19041, has properties similar to those of conventional flame-retardant PET grades. The polyester elastomer, Hytrel RS, is based in part on renewable raw materials. In this 20 to 60 % of the polyols are derived from renewable raw materials. T...

... 250 to 270°C restrict their use. Figure 3 gives a comparison of the properties of Sorona 3030G PTT GF 30 and both PBT GF 30 and PET GF 30. Thermal aging studies indicate that Sorona 3030G NC010 (PTT GF30) has good properties comparable to those of Rynite 530 NC010 (PET GF30). Figure 4 presents various strengths as a function of heat storage time (5,000 h at 120°C and 140°C) for Sorona 3030G NC010 and Rynite 530 NC010, both being products with 30 wt.-% glass fiber-reinforcement.
