CS-2512 is a high-efficiency foaming masterbatch specifically formulated for polystyrene (PS) light diffusion panels. Engineered with a PS-compatible carrier, this advanced foaming agent delivers ultra-fine cell structure, exceptional optical clarity, and unmatched processing stability, making it the ideal choice for premium light diffusion applications.


Key Features & Benefits:

✔ PS-Optimized Formulation – Eliminates screw sticking, black spots, and yellowing issues common in PS foaming.
✔ Superior Optical Performance – Enhances light diffusion uniformity and whiteness for crystal-clear LED panels.
✔ Fine & Uniform Cell Structure (200-250μm) – Ensures smooth surfaces and consistent light transmission.
✔ High Production Yield – Improves manufacturing efficiency by 5-8% compared to standard foaming agents.
✔ Excellent Thermal Stability – Decomposition range of 200-210°C, ideal for PS processing.
✔ Eco-Friendly & Low Residue – Meets environmental standards while reducing machine contamination.

Recommended Dosage: 0.2–0.5% (optimized for PS foaming processes).


Primary Applications:

1. LED Lighting Components

  • Light diffusion panels for LED bulbs, tubes, and fixtures.

  • Backlight modules for TVs, monitors, and automotive displays.

2. Decorative & Architectural Panels

  • Frosted-effect panels for modern interior design (e.g., ceilings, partitions).

  • Backlit signage with uniform brightness and no defects.

3. Consumer Electronics

  • Light guide plates for LCD/LED screens and touch panels.

  • Diffuser sheets for electronic displays and control panels.

4. Protective Packaging

  • Lightweight foam inserts for fragile items (electronics, glass, medical devices).

  • Sustainable cushioning materials with shock-absorbing properties.

5. Specialty Foam Products

  • Acoustic insulation boards (sound-damping properties due to fine cell structure).

  • Thermal insulation sheets for construction and industrial use.
