Proven ProductsCelite® functional additives have been used for antiblocking in polyethylene film for over 50 years. Celite® antiblock additives reduce the tendency of thermoplastic film to adhere when compounded as plastic packaging or tightly wound rolls. Addition rates as low as 2,000 ppm provide significant reductions in block/re-block forces. This efficiency results from the unique, irregular particle shapes of the diatoms. Films containing Celite® antiblock additives exhibit exceptional clarity. A range of products with different particle

sizes and shapes is available to optimize efficiency and cost effectiveness. The original grade of Celite® antiblock was Super Floss®. Super Floss® is still the preferred grade and is recommended for most film applications. Super Fine Super Floss® is the grade to consider if your application requires a fine or narrower particle size distribution. Micro Ken® 801, White Mist® PF, Super Floss® MX, Super Floss® A and Super Floss® E complete the product line.

Features and BenefitsCelite® diatomaceous earth antiblock additives exhibit minimal interactions with other additives in most LDPE and LLDPE resin systems. This assures that the optimal amount of processing aids and other organic additives are used.

C e l i t e ® a d d i t i v e s o f f e r s u p e r i o r economic performance in higher alpha olefin LLDPE systems in which synthetic silica might otherwise be specified. One study, presented by a leading resin producer at ANTEC ‘99, showed the statistical equivalence of Super Floss® to synthetic silica in a 1-octene LLDPE system.

A primary objective of our R&D efforts is a continuing product development program, directed at enhancing product performance and assuring multi-plant sources to a growing worldwide market. The latest result of this intense effort is the successful introduction of Super Floss® MX in North America, and further significant breakthroughs in antiblock technology are on the horizon.

Antiblock Basics and ApplicationsThe theory of antiblocking is that varied particle shapes of diatomite particles protrudes from, or are at the surface of, the polyethylene film. The irregular shaped particles of Celite® diatomite silica are extremely efficient for this application in all types of polyolefin films including LLDPE, metallocene PE and polypropylene. Depending on the type of resin used to make the film and the end use application, the amount of Celite® antiblock required usually ranges from 0.2% to 0.5% by weight of the resin. Due to the critical nature of incorporating a solid into a solid plastic film, Celite® products meet exacting quality control standards. This allows the end user to be assured of a consistent quality antiblock additive batch after batch.

In addition to traditional applications in film, Celite® additives are used in a wide variety of plastic, plastomer and compounded polymer systems: • Antiblocking, prevention of plate out and gloss control in PVC sheets • Silica nucleation site for polyurethane • Reinforcement and dimensional stability in siloxane (RTV) and extension of the pyrogenic silica • Mold release and gloss/sheen control of various other resin systems
