Nylon - 20% Glass Filled & 6/6
Nylon 6/6
Nylon 6/6 has high mechanical strength and rigidity. It is resistant to chemicals and is stable at high temperatures.
Price: $
Common applications: Automotive applications, gears, bushings
20% Glass-Filled Nylon
20% Glass-Filled Nylon is much stiffer and has greater tensile strength than standard Nylon. It also has a low coefficient of friction and high thermal resistance.
Price: $$
Common applications: Bearings, washers, a lightweight substitute for metals where appropriate
PBT
Polybutylene Terephthalate (PBT) is similar to PET plastic and a member of the polyester family. PBT is better suited to lower molding and use temperatures. It also has high heat and chemical resistance.
Price: $
Common applications: Automotive applications, gears, electrical components
PC/ABS
PC/ABS is a blend of polycarbonate and ABS, meaning you get the best properties of both base materials—heat resistance and flexibility. This blend is also more easily processed during injection molding than either of the base materials.
Price: $
Common applications: Enclosures, large panels; widely used in many applications
PEEK
Polyetheretherketone (PEEK) has high temperature, chemical, and radiation resistance.
Price: $$$
Common applications: Because it is so robust, it is well suited for applications in the medical, nuclear, chemical processing, and aerospace industries.
Ultem (PEI)
Polyetherimide is a semi-transparent plastic with high temperature resistance and very high dielectric strength, making it great for medical instrument components and electrical insulation parts.
