High Heat Resistance Bakelite Parts Supplier
-
We are surrounded by objects, most of which, some way or the other
have a polymer associated with them. The ease of moulding polymers into
different shapes and their relatively low cost of production has been The main
reason for their universal usage. As such, Bakelite is one of the commercial
manufactured polymers that we witness in our daily lives.
Bakelite is the
commercial name for the polymer obtained by the polymerization of phenol and
formaldehyde. These are one of the oldest polymers that were synthesized by man.
Phenol is made to react with formaldehyde. The condensation reaction of the two
reactants in a controlled acidic or Basic medium results in the formation of
ortho and para hydroxymethyl phenols and their derivatives.
When the phenol
is taken in excess and the reaction medium is made acidic, the product of the
condensation reaction obtained is acidic. Whereas, when the quantity of
formaldehyde taken is is acidic. Basic medium, the condensation product is known
as resol.
Bakelite is obtained when novolac is allowed to undergo
cross-linking in the presence of a cross-linking agent. In general, phenol taken
in middle acts as the cross-linking agent. Cross-linked product of phenol and
formaldehyde have the following structure.
Cross-linked product of phenol and
formaldehyde
Uses of Bakelite
Now coming to the uses of Bakelite, since
this element has a low electrical conductivity and high heat resistance it can
be used in manufacturing electrical switches and machine parts of electrical
systems. It is a thermosetting polymer and Bakelite has high strength meaning it
basically retains its Form even after extensive moulding. Phenolic resins are
also extensively used as adhesives and binding agents. They are further used for
protective purposes as well as in coating industry.
Further, Bakelite has
been used for making the handles of variety of utensils. It is one of the most
common and important polymers that are used to make different parts of many
objects.
