PC | Policarbonate - Thermoplastic polymers, elastomers and additives

Although the main structure of the polycarbonate chain is frozen at room temperature, thanks to its phenylene, isopropylidene and carbonate groups, it has sufficient mobility to dissipate impact energy at room temperature. Mechanically it is a plastic that has great hardness. According to the Rockwell hardness tests by the UNE-EN ISO 2039-2: 200 standard, the polycarbonate resin has a hardness in the M scale of 75. It is also very resistant to traction, compression and especially impact; and even breaking it has a great resistance to fragmentation. Despite this great resistance, it scratches very easily and its scratching is not easy to repair. It is 300 times stronger than glass and 30 times stronger than acrylic. With what it offers a margin of security that does not give any other material designed for encristalado.

At 1409cm-1 the asymmetric deformation vibration of the CH3 groups appears while the symmetric deformation of the C (CH3) 2 is at 1368cm-1. Between 2000 and 1650cm-1, very weak combination bands of the polymer phenyl groups appear. At 1077cm-1 and 1008cm-1 appear under the deformation vibration bands of the CH of the phenyl group; the vibration is in the plane. The peaks corresponding to 884, 823 and 759cm-1 correspond to the deformation bands of the same CH, but the vibration is outside the plane.

The artifacts in the PC pellets are generally made by injection molding, blow molding and extrusion, and can then be processed with the standard equipment for carpentry and metallurgy without suffering cracks, pitting, breakage of any kind. The films and fibers are produced by extrusion or solution. The first can be subsequently thermoformed, and like the other PC stick semi-easily made with epoxy adhesives and ultrasonic welding.

Polycarbonate is a material that allows its use in countless applications. As we have seen its properties of transparency, impact resistance and its ability to withstand temperatures of up to 130 ° C, are common to all varieties of polycarbonate. The polymer PC is used as a basis for photographic films, on screens, a helmet and safety glasses, in lenses for glasses; electric diffusion covers, flight components, lighting systems, laminated sheets for bulletproof glass, moons and headlights for cars, lenses for glasses, solar collectors, furniture and kitchen utensils, utensils suitable for microwaves, sterilization of medical components , compact disc (CD), plates, tubes, sheets, optical fibers, plugs, coffee machines, filters, canteens, slide frames, pens, parts for office machines, cameras, projectors, photometers, binoculars, watches, supports optical computer memory. Polycarbonate is the most suitable material to replace glass in many applications, which represents an important weight saving, because polycarbonate is much lighter than glass. In addition, polycarbonate can take curved shapes very easily, can be in transparent or opaque colors and in case of breakage, it does not occur in a fragile way bursting into a thousand pieces.
