Premium Milky White Diffuser PC Profile
High-performance building-grade polycarbonate profiles for architectural and construction applications
Dachang's polycarbonate extruded profiles are precision-engineered building-grade PC profiles featuring a distinctive milky white diffuser finish. Unlike standard transparent or opaque polycarbonate profiles, our milky diffuser profiles provide optimal light transmission with soft, even light distribution-making them ideal for architectural glazing systems, glass partition edge trim, decorative building moldings, and interior light diffusion applications.
As a leading custom polycarbonate profile manufacturer with over 27 years of plastic extrusion expertise, we specialize in OEM/ODM production for global construction material suppliers, LED lighting fixture manufacturers, and building component distributors. Our advanced extrusion lines and in-house mold workshop enable 72-hour custom mold delivery-significantly faster than the industry average of 2-3 weeks.
What Makes Our PC Profiles Different?
Milky White Diffuser Finish
Unique light-diffusing surface provides 85%+ transmittance with uniform distribution-superior to standard frosted or clear PC profiles.
Ultra-Lightweight Design
At only 90g/meter, our profiles are 15-20% lighter than comparable products, reducing shipping costs and simplifying installation.
Precision Building Dimensions
28mm × 12mm cross-section engineered for standard glass partition systems and architectural edge trim applications.
Construction-Grade Durability
Virtually unbreakable polycarbonate material withstands mechanical stress in high-traffic building environments.

FAQ
Q: What is the difference between polycarbonate and acrylic profiles?
A: Polycarbonate (PC) offers approximately 30x higher impact resistance than acrylic (PMMA). PC profiles are virtually unbreakable and maintain structural integrity under mechanical stress, making them ideal for safety-critical building applications. Acrylic provides better optical clarity and scratch resistance but is more brittle.
Q: Can you produce custom polycarbonate profile shapes?
A: Yes, we specialize in custom profile extrusion. Provide dimensional drawings (DWG, DXF, PDF, or hand sketches) or physical samples. We can produce complex geometries including hollow sections, multiple chambers, and co-extruded multi-material designs.
Q: What is the MOQ for custom polycarbonate profiles?
A: Minimum order for custom profiles is 500 meters. Standard catalog profiles start at 200 meters. Contact us to discuss sample orders for testing and validation before production runs.
Q: How long does custom mold fabrication take?
A: Standard-complexity molds complete within 72 hours-one of the fastest turnarounds in the industry. Complex profiles may require 5-7 working days. First samples are produced within 3-5 days after mold completion.
Q: What surface finishes are available?
A: We offer clear/transparent, milky white diffuser, frosted/matte, opal translucent, and opaque in standard or custom colors. Special finishes including textured, high-gloss polished, and soft-touch coatings are also available.
Q: Are your profiles suitable for outdoor use?
A: Yes, our UV-stabilized formulations are designed for exterior applications. UV stabilizers prevent yellowing and degradation from prolonged sun exposure, ensuring long-term clarity and performance.
