Polycarbonate Grades We Work With

There are various grades and types of polycarbonate available, each tailored to specific applications and requirements. Some common polycarbonate grades include:


CNC Machining General-Purpose Polycarbonate (GPC)

This is the standard grade of polycarbonate used in many applications due to its excellent impact resistance, transparency, and high-temperature resistance. GPC is often used in consumer goods, automotive parts, and construction.

CNC Machining UV-Resistant Polycarbonate

This grade contains additives that enhance its resistance to ultraviolet (UV) radiation, making it suitable for outdoor applications where prolonged exposure to sunlight may occur. It helps prevent yellowing or degradation caused by UV rays.

CNC Machining Flame-Retardant Polycarbonate

This type of polycarbonate includes additives that improve its fire resistance, making it suitable for applications where fire safety is crucial, such as in electrical enclosures or components.

CNC Machining Glass-Filled Polycarbonate

By incorporating glass fibers into the polycarbonate resin, this grade enhances stiffness, strength, and dimensional stability. It is often used in applications that require higher mechanical strength and rigidity.

CNC Machining Bullet-Resistant Polycarbonate

Engineered to provide extremely high impact resistance, this grade of polycarbonate is used in applications where protection against ballistic threats is necessary, such as security glazing or armored vehicles.

CNC Machining Medical-Grade Polycarbonate

Designed to meet stringent requirements for biocompatibility, sterilization, and transparency, this grade is used in medical devices, including surgical instruments and medical equipment housings.

Food-Grade Polycarbonate complies with regulations set for food-contact applications, ensuring safety for use in items like food containers, kitchenware, and equipment used in the food industry.

The choice of polycarbonate grade depends on the specific properties required for the intended application. CNC machining can be applied to various polycarbonate grades, allowing for precise shaping, cutting, and milling according to the needs of the project or product. When working with CNC machining for polycarbonate, it’s essential to select the appropriate grade based on factors such as mechanical properties, environmental conditions, regulatory requirements, and end-use applications.
