Polyamide
Polyamide - PolyJARID
Polyamide 6 (PA6), Polyamide 6.6 (PA66), Polyamide 12 (PA12)
Polyamides are semi-crystalline thermoplastics, the properties of which (especially PA6 and PA66) depend very strongly on the water content . No other thermoplastic contains such a combination of hardness and strength with such tenacity and tensile strength. Their balanced characteristics make Polyamides one of the most widely used plastics in engineering. Download PolyJARID Catalogue
