Durethan® BKV30XTS3

30% Glass Reinforced, Injection Molding, Heat Stabilized

General Information

Durethan® is the trade name for our range of engineering thermoplastics based on polyamide 6 and polyamide 66. These polyamides are partially crystalline thermoplastics which offer an ideal combination of properties, especially for technical applications. They provide high mechanical strength and stiffness, good dielectric properties, high resistance to both heat and chemical attack, and good friction and wear properties.
