3. In this presentation we are going
to let you know about :
The material that used to produce a Non-
stick frying pan.
The properties of the materials.
The reason of using those material.
The environmental issue that the
material bring to us.
5. Chemical Composition:
Chromium - 18-20%
Nickel - 8-10.50%
Manganese - 2.00% max
Carbon - 0.08% max
Sulfur - 0.030% max
Silicon - 1.00% max
Phosphorus - 0.045% max
Structure:
Austenitic metallurgical structure.
6. Synthetic polymers obtained by the
reaction of phenol or substituted
phenol with formaldehyde.
In the form of Bakelite, they are the
earliest commercial synthetic resin.
7. Formed by a step-growth
polymerization reaction that can
be either acid- or base- catalysed.
Found in myriad industrial
products.
First plastic made from synthetic
components.
Widely used for its heat-resistant
properties in kitchenware.

does not bend and break under
normal use.
Reasonable manufacturing cost.
27. 2) PHENOLIC RESINS:
Wont break, deform or melt under
high temperatures.
Will not burn user’s hands.
Durable.
Will not slip out of user’s hands.
Promote sales.
