What is polycarbonate?
Polycarbonate is a high-performance tough and transparent amorphous thermoplastic engineering plastic. It has organic functional groups linked together by carbonate groups (–O–(C=O)–O–).
What are the Characteristics of Polycarbonate?
High Impact Strength – Polycarbonate has a high strength that makes it resistant to impact and fracture.
Optical clarity – Polycarbonate can transmit around 90% of light as good as glass.
Lightweight – Polycarbonate has a density of 1.2 – 1.22 make it an excellent alternative to glass.
Chemical Resistance – Good chemical resistance against diluted acids, aliphatic hydrocarbons, and alcohols.
High temperature resistance – Polycarbonate have high heat resistance up to 135°C.
UV resistant – Polycarbonate can be designed to UV resistant with 100% protection from harmful UV rays.
Optical Nature – Polycarbonate offers excellent optical properties with refractive index 1.584.
Dimensional stability – Polycarbonate maintains Dimensional stability between -20°C to 140°C.
Polycarbonate sheet, tube, rod, film
Polycarbonate is available in sheet stock and rod stock, making it a good option for subtractive machining processes on a mill or lathe.

What Are The Different grades of Polycarbonate?
Polycarbonate was developed in the middle 20th century by GE in the United States and Bayer in Germany. Well known Trade names are Lexan® by SABIC, and Makrolon® by Bayer MaterialScience. There are different industry grades of polycarbonate available. Most are typically differentiated by the amount of glass fiber reinforcing they contain and the variance in melt flow between them.
how is Polycarbonate processed?
Polycarbonate sheets can be bent or deformed by both hot and cold bending method.
We Use a fine-tooth blade with table saw to cut polycarbonate sheets with a small tolerance around +/- 1mm.
We provides vacuum formig service with Polycarbonate sheets which is ideal for custom trays and panels.
We provide both low and high volume polycarbonate injection molding service in a short time tooling building.
We manufacture cutomed polycarbonate sheets, rods, tubes, profiles through our Polycarbonate Extrusion service.
Our CNC Machining for Polycarbonate Parts offers excellent dimensional stability and mechanical properties.
Is Polycarbonate recyclable?
Yes, Polycarbonate plastic is 100% recyclable and identified by recycling code “7”.
Is Polycarbonate Toxic?
BPA Free Polycarbonate plastic is a perfect material for baby bottles, refillable water bottles, sippy cups, and other food and beverage containers. so it is not toxic, but there is a potential that certain types of polycarbonate could be hazardous in food contact situations due to the release BPA.
What are the Disadvantages of Polycarbonate?
Polycarbonate is very susceptible to scratching. For this reason, clear polycarbonate lenses will typically be coated with a scratch-resistant layer for protection.
