TechnoDur Line

Extremely hard, favourable sliding and wear characteristics

TechnoDur: Braves extremely low Temperatures
Our new TechnoDur PBT compound is a thermoplastic which combines great hardness, stiffness and strength. The compound is easily processed due to its perfect flow behaviour. The favourable sliding and wear characteristics as well as extremely high tenacity in temperatures below freezing are further advantages.

TechnoDur is manufactured by poly-condensing terephthalic acid or dimethyl terephthalate containing butandiol-1,4 using special catalysts.

Product Segments
The TechnoDur compound line consists of non-reinforced, glass fibre reinforced, impact strength modified and flame retardant compounds.

Typical Applications:
TechnoDur compounds may be applied in the following areas:

• Electrical engineering: Lamp holders, micro switches, spools, brush-holder bridges, switches, cam divides, telephone housings ...
• Automobile construction: Junction boxes, petrol filters, fuel tank caps, heating folds, headlights, car body panels,
  spark plug connectors ...
• Household appliances: Hair care appliances, components for toasters, fondue makers, coffeemakers ...
• Ohter applications: pump components, gears, guide, slide bearings and components ...

Pre-drying:
We recommend to pre-dry the compounds at 120 °C for approx. 5 hours (air-dryer) in order to obtain mechanically and visually flawless injection moulded parts. The drying period must be extended accordingly when using open packaging units or ground material.

Higher tool temperatures reduce tension in the injection moulded parts, resulting in better surfaces, better embedding of the glass fibres, higher degree of crystallisation and low post-shrinkage.
