Polycarbonate is an advanced material. Thus, when considering polycarbonate profiles for an extrusion project, you need to ensure that your manufacturer has experience in extruding polycarbonate! And Keller Products can deliver. We have years of experience both designing AND manufacturing polycarbonate.
Polycarbonate is an excellent material for plastic profiles. Polycarbonate profiles have great stiffness, toughness, impact resistance and are clear. Polycarbonate profiles have excellent colorability with a beautiful gloss finish that can mimic glass and metal. Polycarbonate profiles have very good electrical insulation characteristics, do not burn readily, and some people claim that Polycarbonate can be considered “self extinguishing.” Additionally, Polycarbonate profiles have great dimensional stability and service temperatures close to 300° F.
Polycarbonate profiles can be used outdoors but some yellowing in clear Polycarbonate profiles can occur after years in use. Polycarbonate profiles have fair to good resistance to solvents, but may have a tendency to stress crack upon exposure to certain chemicals. Polycarbonate profiles have good stain resistance to coffee, tea, fruit juices, inks, soaps, detergents, and cosmetics.
Polycarbonate profiles also have excellent electrical properties and light transmittance values—typically ranging from 86-90%. In addition, flame retardant grades are available, along with special grades that are clear AND flame retardant (typically used in the transportation industry). Polycarbonate profiles present unique manufacturing challenges—they must be dried well below recommended levels to maintain maximum impact strength. In polycarbonate profiles, the gloss levels of the finished product are typically high. At Keller Products, we can overcome this by using special additives that will result in a matte finish if desired.
