What is the PC used in the PC plastic candle holders what is its purpose?

Polycarbonate (PC) plastic is a naturally transparent amorphous thermoplastic. Although they are commercially available in a variety of colors (which may may be translucent), the internal light transmittance of this raw material is almost the same as glass. Polycarbonate polymers are used to produce a variety of materials. Polycarbonate polymers are particularly useful when the product requires impact resistance / transparency (for example, in bulletproof glass). PCs are commonly used for plastic lenses in glasses, medical equipment, automotive parts, protective equipment, greenhouses, digital disks (cd, dvd, blue light), external lighting devices. Polycarbonate also has good heat resistance can be combined with flame-retardant materials without significant material degradation. Polycarbonate plastics are engineering plastics because they are often used for stronger stronger materials, such as impact-resistant "glass-like" surfaces.

What are the characteristics of polycarbonate?

Now that we know its purpose, let us examine some of the key properties of polycarbonate. PC is classified as a "thermoplastic" (as opposed to "thermoset"), this name is related to the way plastics react to heat. The thermoplastic material becomes liquid at its melting point (polycarbonate is 155 degrees Celsius). One of the main useful properties of thermoplastics is that they can be heated to the melting point, cooled, then heated again without significant degradation. Thermoplastics like polycarbonate can be easily injection molded then recycled rather than burned.

In contrast, thermoset plastics can only be heated once (usually during the injection molding process). Heating causes the thermosetting material to solidify (similar to a 2-component epoxy resin), causing irreversible chemical changes. If you heat a thermosetting plastic to a high temperature, it will burn. This characteristic makes thermoset materials unsuitable for recycling.
