Grivory HT is a high-performance, semi-crystalline thermoplastic construction material based on polyphthalamide (PPA).
The Swiss company EMS-GRIVORY has developed its own innovative process for the polymerization and compounding of Grivory HT. EMS-GRIVORY has grown to become one of the world’s leading manufacturers of PPA, and the foremost producer on the European market.
The material is characterized by properties that result in very high performance across a number of application areas. Plastic details made of Grivory HT retain their shape even at high operating temperatures. Thanks to its characteristic properties, such as high stiffness and good strength, it is one of the most commonly used materials for metal replacement.
Grivory HT is supplied in granulate form for injection-molding, and can be processed using conventional, commercially available machines and tools.
The material is characterized by the following properties:
- Good stiffness and high strength even at high temperatures
- Low moisture absorption
- Good dimensional stability
- Good resistance to oils and chemicals
The Grivory HT family consists of the following products:
Grivory HT1 PA6T/6I
Grivory HT2 PA6T/66
Grivory HT3 PA10T/X (GreenLine)
The materials are available with different reinforcing agents and varying concentrations. It is approved for contact with foodstuffs and drinking water (FWA).
Grivory HT is used in application areas such as vehicles, sanitation, and household appliances.
