Heat Deflection Temperature(℉): 280°F
Optical Grade Polycarbonate
Optical Grade Polycarbonate is specially engineered for applications requiring exceptional optical clarity and transparency. This material is highly regarded in industries such as eyewear, optical lenses, and displays because it combines high light transmission, resistance to yellowing, and impact strength, making it a reliable choice for injection molded precision optical components.
Tensile Modulus(MPa): 2400 MPa
Tensile Strain (Yield): 6%
Rockwell Hardness(M-Scale and R-Scale): M75, R110
Heat Deflection Temperature(℉): 280°F
UV-Resistant Polycarbonate
UV-Resistant Polycarbonate incorporates additives that protect the material from ultraviolet (UV) degradation, ensuring a longer service life when exposed to outdoor conditions. This variant maintains its mechanical properties, clarity, and dimensional stability even in harsh sunlight, making it ideal for outdoor injection molded products such as signage, skylights, and protective covers.
Tensile Modulus(MPa): 2400 MPa
Tensile Strain (Yield): 6%
Rockwell Hardness(M-Scale and R-Scale): M75, R110
Heat Deflection Temperature(℉): 280°F
Flame-Retardant Polycarbonate
Flame-Retardant Polycarbonate is formulated with fire-resistant additives that reduce flammability and self-extinguish when exposed to flame. This enhanced safety feature makes it suitable for injection molded electrical and electronic housings, lighting fixtures, and automotive components, where fire safety and compliance with stringent regulations are essential.
Tensile Modulus(MPa): 2300 MPa
Tensile Strain (Yield): 6-7%
Rockwell Hardness(M-Scale and R-Scale): M75 – M85, R110
Heat Deflection Temperature(℉): 270°F
Glass-Filled Polycarbonate
Glass-Filled Polycarbonate is reinforced with glass fibers, improving its mechanical strength, rigidity, and thermal stability. This composite material is ideal for high-performance injection molding applications that require increased structural support, such as automotive, industrial, and electrical components, offering enhanced load-bearing capacity and resistance to deformation under stress.
Tensile Modulus(MPa): 4500-5000 MPa
Tensile Strain (Yield): 3-5 %
Rockwell Hardness(M-Scale and R-Scale): M90 – M100, R120 – R130
Heat Deflection Temperature(℉): 320°F
Impact-Resistant Polycarbonate
Impact-Resistant Polycarbonate is engineered for superior toughness and resistance to physical impact. Known for its ability to withstand harsh conditions, this material is widely used in injection molded safety equipment, eyewear, protective covers, and automotive parts, where durability and protection against high-impact forces are crucial.

Surface Finishing Options for Polycarbonate Injection Molding
NOBLE offers a range of surface treatments as part of its polycarbonate injection molding services to enhance the quality of each molded product. Each surface treatment is tailored to improve the mechanical properties, durability, and aesthetic appearance of molded polycarbonate parts.
Polishing
Working on metal and hard plastics, our polishing uses highly efficient machinery to get our parts between Ra 0.8~Ra0.1 for a cleaner surface.
Electroplating
Electroplating reduces metal cations in the electrolyte solution, producing a metallic coating on a metal surface. This process can be used for purposes of corrosion and wear resistance, as well as for decorative purposes.
Powder coating
We apply a thin layer of protective polymer with the corona discharge phenomenon to give our part a lasting finish that protects from impacts and prevents wearing down.
Sand Blasting
Band blasting cleans the surface of any impurities and peels coating through the propelling of blast media streams over the parts.
Laser Carving
Helpful in brand recognition or parts organization, we use laser carving that applies various printing methods during full-scale production to quickly embed barcodes, lettering and logos on the parts.
