POLYMERIC BLEND FOR DOMESTIC SWITCHES
Presently in India the urea and
Phenyl Formaldehyde are used in Electrical accessories like switches,
plugs, sockets etc. These material
are brittle while most of the developed countries uses Polycarbonate
which are resilient material and expensive. ERDA
in Vadodara has developed a Polymeric blend that is economical as
Formaldehyde and having properties similar to Polycarbonate. It has
withstood the tracking resistance at 250 Volts. Other properties are
as follows: ·
Mechanical strength( Specimens were subjected to 10
blows of suitable impact test
apparatus), the result
was that no cracks were observed ·
Ball Pressure Test at 125 deg Celsius: The Depth of
indentation was less than 2mm. ·
Water absorption at ambient temperature for 24
hours, (%): 0.7. |
