Modified Polycarbonate Plastic Resin: Engineered for superior impact resistance, high - temperature resistance, and flexibility. Ideal for automotive and electronics applications

Light Diffusion PC product models in the LED lighting field

Production Description:

Modified Polycarbonate (PC) is engineered through a meticulous process to enhance the inherent properties of standard PC

Key Advantages Over Standard PC:

• 1. Raw Material Selection: High - purity polycarbonate resin is chosen as the base material. This resin is known for its transparency, impact resistance, and thermal stability.
  2. Modification Process: Additives such as impact modifiers, heat stabilizers, UV absorbers, flame retardants, and reinforcing agents are added according to specific requirements. These additives are blended with the PC resin using high - efficiency mixers to ensure uniform distribution.
  3. Compounding Extrusion: The mixture is fed into a twin - screw extruder. Under high - temperature and high - shear conditions, the materials are fully melted, mixed, and plasticized into a homogeneous compound. The extruder's temperature profile is carefully controlled to maintain the quality and properties of the material.
  4. Pelletizing: The extruded compound is cooled and cut into uniform pellets. These pellets are the final form of the modified PC material and are ready for further processing.
  5. Quality Control: Throughout the production process, strict quality control measures are implemented. Tests such as mechanical property evaluation, thermal analysis, and optical property measurement are conducted to ensure the modified PC meets the desired specifications and performance criteria.
