Grivory® is the trade name for a group of technical thermoplastics manufactured and distributed by EMS-GRIVORY. Grivory HT is a semi-crystalline thermoplastic construction material based on polyphthalamide (PPA).

EMS-GRIVORY, based in Domat/Ems (Switzerland), developed its own innovative process to manufacture, polymerise and compound Grivory HT. Production capacity has been adjusted to meet strong demand. EMS-GRIVORY has grown to become one of the world’s leading providers of polyphthalamides and leads the field on the European market.

Grivory HT is characterised by its high-performance properties. Technical injection-moulded parts made from Grivory HT retain their shape even at high operating temperatures. Thanks to its properties, Grivory HT is undoubtedly a high-performance plastic. In terms of characteristics such as stiffness and strength, among the most important in metal replacement, Grivory HT outperforms materials such as PPS or PEEK at operating temperatures up to 120°C.

Grivory HT is supplied in granulate form for injection moulding and can be processed using conventional, commercially available machinery and tools.

Grivory HT is used for the efficient manufacture of high-quality technical components that are characterised by:

  • stiffness and strength at high operating temperatures
  • little change in property values after absorption of water
  • good dimensional stability and low warpage
  • good chemical resistance
  • good surface quality
  • economical production

The Grivory HT grades:

The Grivory HT product range includes a number of groups with different base polymers.

  • Grivory HT1:PA6T/6I
  • Grivory HT2:PA6T/66
  • Grivory HT3:PA10T/X

 

Grivory GV and Grivory HT products are supplied ready for injection-moulding processing. The Grivory HT3 product range also includes extrusion grades.

The groups contain a wide range of grades, which vary in terms of the type and concentration of the reinforcing agents (glass fibers, minerals) used, the stabilisers and the processing aids.

Grivory FWA products are physiologically harmless and are also used in sensitive application areas with direct contact to drinking water and foodstuffs.
