Description
Premium Engineering Grade Extruded Clear Polycarbonate Sheet is a high-performance, amorphous thermoplastic characterized by its high dimensional stability, low moisture absorption, and excellent rigidity. This versatile material can withstand long-term service temperatures ranging from -40°C to 115°C, with a short-term maximum service temperature of 140°C. It has a water absorption factor of just 0.2%, ensuring dimensional stability even in humid environments.
Typical applications for this Premium Polycarbonate Sheet include industries such as electrical and electronics, safety engineering, and vehicle construction. It is well-suited for CNC routing, CNC milling, and CNC turning, making it a preferred choice for various manufacturing processes.
It is important to note that Engineering Grade Polycarbonate is not optically clear and should be selected for its technical and mechanical properties rather than aesthetic qualities.
