What is PC and what is it for? Polycarbonate plastics (PC) are a naturally transparent amorphous thermoplastic. What is polycarbonate? Although they are commercially available in a variety of colors (perhaps translucent and perhaps not), the raw material allows the internal transmission of light almost in the same capacity as glass. Polycarbonate polymers are used to produce a variety of materials and are particularly useful when impact resistance and / or transparency is a product requirement (for example in the ball test glass). The PC is commonly used for plastic lenses in glasses, in medical devices, car components, protective equipment, greenhouses, digital discs (CD, DVD and Blu-ray) and lighting lights . Polycarbonate also has very good heat resistance and can be combined with materials from flames without significant degradation of materials. Polycarbonate plastics are engineering plastics in that they are generally used for more capable and robust materials such as in "glass" surfaces resistant to impact. The following diagram shows the relative impact resistance of polycarbonate compared to the impact resistance of other commonly used plastics such as ABS, polystyrene (PS) or nylon.

It can generally be formed at room temperature without cracking or breaking, similar to aluminum sheet. Although deformation can be simpler with the application of heat, even small corner turns are possible without it. This characteristic makes the stock of polycarbonate sheets particularly useful in prototyping applications where the sheet has no viability (for example, when transparency is required or when a non -conductive material with good electrical insulation properties is necessary). What are the characteristics of polycarbonate? Now that we know what it is used for, let's examine some of the key properties of polycarbonate. The PC is classified as a "thermoplastic" (as opposed to "thermodoste"), and the name has to do with the way plastic reacts to heat. Thermoplastic materials become liquid at their melting point (155 degrees Celsius in the case of polycarbonat). A major useful attribute on thermoplastics is that they can be heated to their melting point, cooled and heated without significant degradation. Instead of burning, thermoplastics like Liquefy polycarbonate, which allows them to be easily molded by injection and then recycled. On the other hand, thermoducis plastics can only be heated once (generally during the injection molding process). The first heating causes the adjustment of thermosetting materials (similar to an epoxy in 2 parts) resulting in a chemical change which cannot be reversed. If you were trying to heat a high temperature thermosetting plastic for a second time, it would just burn. This characteristic makes thermoducted materials poor candidates for recycling.

Amorphous plastics generally show a tendency to soften gradually (that is to say that they have a wider range between their glass transition temperature and their melting point) rather than presenting a clear transition from the solid liquid as is the case in crystalline polymers. Copolymer in that it is made up of several different types of monomers in combination with each other. Why is polycarbonate used so often? Polycarbonate is an incredibly useful plastic for applications requiring transparency and resistance to high impact. It is a lighter alternative to glass and a natural UV filter, so it is often used in glasses. At Creative Mechanisms, we used polycarbonate in a number of applications in a range of industries. Some examples include the following elements: Erase windows on prototype models Colored translucent prototypes Transparent tubes for sports equipment pr
