​​​​​​​​​Anti-Blocking Agents

 ​​​Using SYLOBLOC® anti-blocking agents prevents layers of polymer films from sticking together – known as "blocking" in the industry. SYLOBLOC®  anti-blocking agents also enhance surface structure of films resulting in improved scratch-resistance.

SYLOBLOC®  anti-blocking agents are non-toxic, synthetic amorphous silica gels with purity exceeding 99%. Such synthetic silica gels provide several advantages in polymer films and your manufacturing processes including:

          • High efficiency - only low concentrations are needed to attain desired effects     
          • Excellent dispersibility and high film clarity
          • FDA and BGA compliance for the food contact
          • Consistent and reproducible product quality

Combining silica with organic additives such as fatty acid amides can offer additional performance benefits to SYLOBLOC® anti-blocking agent product line. In addition, porosity, average particle size, number of organic additives, and other physical characteristics can be adapted to suit specific requirements.
