What are Polycarbonate Pellets

In the modern injection molding industry, polycarbonate pellets are widely used in household appliances, lighting, electronic shells and general industrial products due to their excellent optical properties, mechanical strength and processing adaptability. PC 2407, as a general-purpose PC grade under Covestro, has performed outstandingly in the mid-to-high-end injection molding market with its advantages such as low viscosity, UV resistance, and easy demolding.

01 | Highlights of material properties

PC 2407 polycarbonate pellets are designed with performance that takes into account both molding fluidity and long-term weather resistance. The following are several core features:

  ・Good light transmittance: Under different thicknesses (1-4mm), the transmittance remains at 87%-89%, making it suitable for highly transparent components.

  ・UV stabilizer addition: The polycarbonate pellets has UV resistance, which can delay the yellowing and aging of products, and is suitable for outdoor or lampshade applications.

  ・Low viscosity and easy demolding: Reduce molding pressure and cycle, and improve injection molding efficiency;

  ・Excellent mechanical properties: Tensile strength, flexural strength and notched impact performance are balanced, which can meet structural requirements.

  ・Flame retardant performance compliance: 0.75mm meets UL94 V-2, 2.7mm meets HB, meeting the flame retardant requirements of most electronic and electrical appliances.

02 | Analysis of Application Fields

Due to its versatility and stability, PC 2407 polycarbonate pellets have been widely used in the following industries:

  ・Consumer electronics shells: mobile phone stands, smart speaker shells, earphone shells, etc.

  ・Lighting fixtures: LED lampshades, diffusers, light guides, etc.

  ・Medical equipment accessories: Non-implantable transparent structural components;

  ・Transparent components of household appliances: juicer covers, water dispenser window panels, control panels, etc.

  ・Industrial transparent parts: instrument covers, Windows, guards, etc.

Its excellent refractive index (1.584) and low haze (0.8%) make it particularly suitable for products with high optical requirements. Meanwhile, its low-temperature impact resistance (the impact value remains above 12 kJ/m² at -30℃) enhances its reliability in cold regions.

04 | Forming characteristics and processing advantages

Polycarbonate pellets PC 2407 has excellent injection molding adaptability and is particularly suitable for processing transparent parts with uniform wall thickness and high appearance requirements. Its melt fluidity is excellent, allowing for rapid mold filling under moderate injection pressure, which helps control surface defects such as flow marks and air streaks on the products.

In terms of mold design, priority should be given to:

  ・Cooling balance: Ensure that the transparent parts do not suffer optical distortion due to temperature differences;

  ・Demolding structure optimization: The material has been added with demolding agent. It is recommended that the mold slope and exhaust position be reasonably arranged to further shorten the molding cycle.

  ・Suitable for multi-chamber structure: Low viscosity helps ensure uniform injection in multi-chamber molds and is suitable for large-scale production.

For scenarios requiring high-speed production, PC 2407 can maintain good fluidity at temperatures below 120℃, and it also features dimensional stability and surface consistency, making it an ideal material choice for automated injection molding lines.

05 | Industry trends and material selection references

As the global trend towards environmental protection and durability continues to advance, the performance of polycarbonate pellets in terms of "long-lasting transparency" and "low VOC" has drawn increasing attention. PC 2407, with the addition of mold release agents and UV resistance, can reduce yellowing in the later stage while maintaining transparency, which is highly suitable for the demands of the smart home, automotive interior and lighting upgrade markets.

In addition, its stable air permeability and low water absorption rate also make it the preferred material for components in electronic structures that attach equal importance to sealing and optics.
