Antifog<br />
Food packaging and horticultural films<br />
used with water-containing products<br />
often fog over on their inner surface<br />
due to the condensation of tiny droplets<br />
of moisture. Droplets are particularly<br />
undesirable in greenhouse films, where<br />
good light transmission is essential for<br />
crop growth.<br />
CESA-nofog additive masterbatches<br />
eliminate the problem by lowering the<br />
surface tension of the water droplets,<br />
causing them to merge and form a<br />

This test was conducted using CESA-stat 3101 in LDPE injection molded plaques,<br />
1 mm in thickness, 3 days after manufacture.<br />
continuous transparent layer that maintains<br />
the clarity of the film. For example,<br />
CESA-nofog 2101 was developed for<br />
LDPE and LLDPE food packaging film.<br />
It does not affect the transparency of<br />
the film and withstands sudden temperature<br />
variations.<br />
Conductive<br />
While the good insulation properties of<br />
polymers are desirable in a wide range<br />
of applications, their typically very low<br />

electrical conductivity sometimes<br />
restricts their area of application. The<br />
use of CESA-conductive compounds<br />
and masterbatches improves electrical<br />
conductivity, enabling plastic parts,<br />
for example, to protect highly sensitive<br />
electronic components from damage<br />
caused by electrostatic discharge.<br />
Conductive compounds are also<br />
increasingly used in components for<br />
transporting hazardous materials.<br />
