Laticonther 80 GR/45 PPS
These grades also meet European Directive 2002/72/EC for food contact applications and BfR (German Federal Institute for Risk Assessment , formerly BgVV, the German Federal Institute for Consumer Health Protection and Veterinary Medicine) standards.Certain grades of PPS comply with ISO 10993 and USP Class VI, and Drug (DMF 14844) and Device (MAF-1097) Master Files have been created for them.
Aerospace Wing and Leading Edge Nose
Fiber-reinforced composites based on ’s high performance polyphenylene sulfide (PPS) make an important contribution to weight reduction of the Airbus A340 and A380. This helps lower fuel consumption and increase range and passenger capacity.
Composites based on PPS are now being used for numerous applications in airplane construction, including the wing nose, the ailerons and the aircraft keel beam. In comparison with aluminum, use of the PPS composites increases design freedom, reduces weight by 20% to 50% and eliminates the possibility of corrosion.PPS already had all the basic characteristics for use in aircraft construction – resistance to high temperatures and aggressive chemicals, hardness, impact strength, dimensional stability and inherent flame-retardancy.
The trick was to create suitable structural elements embodying these attributes. This is done by extruding the PPS into film, combining it with chosen fibrous reinforcements and forming the final part under high pressure at 300°C (572°F). Individual parts are then fabricated from the pressed composites and welded together in an autoclave to form the final component as one piece.

has been working closely with systems and cable manufacturers to develop a number of special (PPS) grades tailored specifically to the requirements of fibre optic technology. The 8670A61 grade has outstanding flow properties, making it ideal for fine-structured design components such as plug connectors, known as ferrules.
Other essential properties for this application are very low water absorption, low creep at high temperatures, good dimensional stability and even shrinkage in both flow and transverse directions. Vectra liquid crystal polymer is also used in fibre optics – particularly for connectors. The crucial factors here are Vectra’s good mechanical properties, even in thin wall sections, and the extreme precision with which ferrules can be made. Ferrules can be injection moulded to incorporate holes to carry the 125 μm thick glass fibres to tolerances of 1-2 μm. These ferrules use Vectra grade A460, specially developed for such applications.
