Spherical silica anti-blocking agent

Using anti-blocking agents prevents layers of polymer films from sticking together – known as "blocking" in the industry. Guanqi anti-blocking agents also enhance surface structure of films resulting in improved scratch-resistance. Guanqi anti-blocking agents are non-toxic, spherical silica powders with purity exceeding 99.6 percent. Such spherical silica powders provide several advantages in polymer films and your manufacturing processes including: ​

l High efficiency - only low concentrations are needed to attain desired effects

l Excellent dispersibility and high film clarity

l Consistent and reproducible product quality

l Combination products and customizable grades

l Excellent yellowing resistance

l Dense bulk density to avoid dust flying

Combining silica with inorganic additives such as silica powder can offer additional performance benefits to Guanqi anti-blocking agents product line. In addition, high addition, average particle size, and other physical characteristics can be adapted to suit specific requirements.
