What is Virgin Polycarbonate

In the current plastic application market, which has increasing requirements for high transparency, high heat resistance and outdoor weather resistance, Virgin Polycarbonate materials have become the preferred choice of many manufacturers and engineers. Among the many grades, PC-1100U from Lotte Chemical has been widely used in high value-added products such as outdoor optical covers, electrical housings, and lighting accessories due to its excellent demoulding properties, UV resistance and stable thermal performance.

01 | Overview of core material properties: medium viscosity, smooth demoulding, and excellent optical performance

PC-1100U uses virgin polycarbonate resin, does not contain recycled materials, and has the following performance advantages:

  ・Excellent transparency and low haze: The transmittance is as high as 89%, and the haze is only 0.8%, which is suitable for products with high optical requirements;

  ・Medium viscosity design takes into account both fluidity and molding stability, suitable for injection molding and extrusion;

  ・Adding mold release agent and UV agent, it has excellent demoulding performance and outdoor weather resistance, UL certification is f1 level, suitable for outdoor lamps and electronic housings;

  ・Flame retardant grade reaches V-2 (1.6mm and 3.2mm), meeting the basic safety requirements of electronic appliances;

  ・The heat deformation temperature is as high as 143°C (0.45MPa), and the long-term working temperature can reach 130°C (RTI);

  ・Stable mechanical strength: flexural modulus reaches 2352 MPa, impact strength reaches 80 kJ/m², strong impact resistance;

  ・The shrinkage rate is only 0.5~0.7%, and the product size is precisely controlled, which is especially suitable for large or precision structural parts.

02 | Application positioning under industry trends: ideal choice for high-end transparent parts and weather-resistant shells

Driven by the "dual carbon policy" and the wave of "high-performance lightweight", Virgin Polycarbonate materials are accelerating the replacement of traditional metals, glass or non-weather-resistant plastics in multiple industries. Especially in the following scenarios, the advantages of PC-1100U are more prominent:

  ・Outdoor lighting lampshades, advertising light box panels: PC-1100U has f1 grade UV stability, long-term anti-yellowing, and maintains optical clarity;

  ・Electronic and electrical housing: It has V-2 flame retardancy and good dimensional stability, suitable for housing products with high requirements for thermal stability and demolding;

  ・Industrial protective masks, transparent safety protective parts: good impact strength and light transmittance, ensuring the dual needs of performance and appearance;

  ・Automobile transparent trim or sunshade structure components: suitable for injection molding/extrusion dual processes, meeting appearance and weather resistance requirements.

03 | Processing advantages: Injection molding and extrusion are compatible, helping efficient mass production

PC-1100U adopts the standard polycarbonate processing window (recommended processing temperature is about 280~310°C), the melt index is 10 g/10min, and it has excellent molding fluidity. It is suitable for:

  ・Injection molding: large-size transparent cover, precision electrical components;

  ・Extrusion molding: transparent sheet, lampshade, shield, building sunshade sheet.

In addition, the internally added release agent combination can significantly reduce demolding friction, increase mold service life and reduce processing energy consumption.
