organics, phenol, and acid halides. Table 4.27 lists the compatibility of
halogenated polyesters with selected corrodents. Reference [1] provides
additional information.
Halogenated polyesters are widely used in the pulpand paperindustry in
bleach atmospheres.
4.10.23 Silicones
The silicone systemsa re quite expensive, beingb ased on organic silicone
compounds (which have silicon rather than carbon linkages in the structure).
They are primarilyu sed for high-temperature service,w here carbon-based
liningsw ould oxidize.
Typically, the silicon atoms will have oneormore side groups attached to
them, generally phenol(C 6 H 5
K
), methyl (CH 3
K
), or vinyl (CH 2 a CH
K
)units.
These groups impart properties such as solvent resistance, lubricity,a nd
reactivity with organic chemicals and polymers. Because these side groups
affect the corrosion resistance of the resin, it is necessary to verify with the
supplier the properties of the resin being supplied.
