Celite functional additives have been
used for antiblocking in polyethylene
film for over 50 years. Antiblock additives
reduce the tendency of thermoplastic film
to adhere when compounded as plastic
packaging or tightly wound rolls.
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.
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.
MINIMAl INTERAcTIoNS with otheR Additives
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.
New product Super Floss MX
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 protrude 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.
Many applications
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
celite antiblocking additives added to the resin formulation of plastic film create a micro-rough surface to keep the layers from sticking together (blocking).
