Antiblock Mineral Additives
for the Plastic Film Industry
Proven Products
Celite® 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 Benefits
Celite® 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.

Celite® additives offer superior
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 Applications
The 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
