Features:

  1. ① Small particle size, low scattering rate, and very high transparency.

    ② Excellent dispersion, no pockmarks and high gloss.

    ③ Good resistance to acid, alkali and temperature can reduce the product color change.

    ④ Stable whiteness, maintain color masterbatch stability.

    ⑤ Less impurities, no harmful substances, can ensure the safety and cleanliness of products.

    ⑥ Low oil absorption, increasing the filler volume to reduce basis material and the cost.

    ⑦ Good affinity to various resins, and improve various mechanical properties of plastic products
