How to Choose the Right Black Masterbatch for UV Protection in Outdoor Products
5 Critical Factors to Select UV-Resistant Black Masterbatch (90% Durability Boost) Choosing the right UV protection black masterbatch prevents color fading, cracking, and premature failure in outdoor plastic products. Over 85% of plastic degradation under sunlight is caused by ineffective UV stabilization. Key factors include carbon black particle size, polymer compatibility, and specialized UV stabilizers. Products with optimized formulations last 5-8 years outdoors versus 1-2 years for standard options. This guide simplifies the selection process using technical data and industry benchmarks. 1. Carbon Black Type & Performance Carbon black determines UV resistance and jetness. Smaller particles (under 20nm) absorb 95% of UV radiation, while larger particles (over 100nm) absorb only 60-70%. High-surface-area carbon blacks (≥ 150 m²/g) enhance black intensity and reduce required dosage by 30-50%. Dispersion quality...
