1. Silaplast™ vs Oleamide/Erucamide
Top 13 Reasons for Silaplast™
# Reason Answer Comment Reference
1 It is thermally stable? Yes
Silaplast™ has a flat COF curve from 20ºC to 60ºC, whereas
oleamide/erucamide based additives show 4 times the variation
2
Will I be able to down-gauge the thickness of my
film?
Yes
Silaplast™ will help in reducing material costs by lowering the
thickness of the film
3 Will my extrusion rate increase? Yes
You can extrude at faster speeds providing lowering of manufacturing
costs
4
Will film treatment immediately after extruding
(corona treatment) get easier?
Yes
Low percentage loading only in the required composite layer greatly
enhances the ability of corona treatment
5
Does it work well with blown as well as cast films?
What about extrusion coating?
Yes
Silaplast™ works very well in the blown film and cast film
manufacturing process. They work well in the extrusion coating
process as well
Primary amide slips have thermal limitations. While they
work well in blown films processed at 400 F, they tend to
volatilize at higher temperatures. They are not suitable for
use with cast films, which are typically made at 500 F to 550
F, or in extrusion coating, which is commonly done at 600 F
6
Does it undergo chemical change, decompose and/or
migrate back into the film?
No
Silaplast™ is very stable even at elevated temperatures >55ºC.
Oleamides and erucamides on the other hand show decomposition
and migrate back into the film hence losing its COF functionality

7 Does it migrate? No
Since Silaplast™ is extremely stable and inert, it does not migrate
between composite layers
8
Will I encounter winding difficulties and
"telescoping" of rolls?
No
Consistent COF values will greatly reduce this issue which arises with
higher chain length amides
9
Will its performance be adversely affected if used in
conjunction with anti-blocks?
No
Some antiblocks absorb erucamide slip molecules and adversely
affect ther diffusion
We also offer a composite slip and antiblock additive under
the Silaplast™-AB tradename that customers can consider
using instead of using two separate additives
10 Is the COF affected during adhesive lamination ? No
Erucamide is attracted to polar substrates and is drawn out and
hence increases the COF. Polar substrates have no effect on
Silaplast™
11
Does it interact with polar polymers like EVA, PET or
EMA?
No
Polar polymers like EVA or EMA can interact with the functional
groups of erucamide slip and retard its migration. Polar substrates
have no effect on Silaplast™
12 Does it interfere with printing and heat sealing? No
Primary erucamide slips interfere with printing and heat sealing
whereas Silaplast™ has no such issues
13
Does it have to be added to every layer of a
multilayer film?
No
Unlike migratory erucamide slips, Silaplast(tm) is only needed in the
outer layers of multilayer films. That makes Silaplast(tm) more cost-
effective in multilayer films, even though higher levels (1% to 2%)
are required in those outer layers
