Clarifying Agent for Polypropylene
FDA Approval, FCN No. 000828
Based on DCBS, NA-2 is the third generation clarifying agent for polypropylene. Comparing with the second
generation clarifying agent NA-1, while keeping the perfect performance in reducing the haze value and
increasing transparency, NA-2 has better performance in odor issue of final polypropylene products. NA-2 is
widely used in high-grade PP products, especially for food contact substances and healthcare stuffs.
NA-2 is listed by FDA of America with FCN No. 828.
