COOKER

Rice cooker or rice steamer is an automated
kitchen appliance designed to boil or steam
rice. Rice cooker consists of heat source, non-
stick inner pot and thermostat.

The first rice cooker was introduced in Japan by
Toshiba in 1955. Due to its huge popularity,
other companies soon joined the market,
adding innovations that expanded the abilities
and features available.

WHAT IS POLYMER-THERMOPLASTIC & PTFE

THERMOPLASTIC-POLYMER PTFE

Thermoplastics are a class of polymers that can Polytetrafluoroethylene (PTFE) is a synthetic

heat, and can be processed either in the heat-
softened state (e.g. by thermoforming) or in the Polytetrafluoroethylene (PTFE), a strong, tough,
waxy, non-flammable synthetic resin produced
liquid state (e.g. by extrusion and injection by the polymerization of tetrafluoroethylene.
molding).
PTFE is distinguished by its slippery surface,
high melting point, and resistance to attack by

almost all chemicals.

APPLICATION OF PTFE IN RICE COOKER

The most frequent application of PTFE globally is in industrial coatings. It
has a very low friction coefficient and high-temperature resistance,

making it perfect for demanding conditions. Most rice cookers have an
inner pot that’s made of aluminum and coated with non-stick PTFE or
know as Teflon. This non-stick coating is used to prevent the rice from

sticking to the pot.

OTHERS APPLICATION OF PTFE

1. PTFE has applications in a huge range of industrial sectors, including
automotive, chemical, electronic, aerospace and medical.

2. PTFE is also used to make containers and pipes because it is anti-
corrosive, and non-reactive.

3. PTFE can be use as a lubricant for machinery.
4. PTFE is used to make gasket because of its strength and heat

resistance.
5. PTFE is used as a thread seal tape for plumbing.
6. PTFE use to insulate cables and connector assemblies because its

has good electric insulation properties.
7. PTFE can also be found in consumer products such as outdoor

apparel, school uniforms, footwear, insoles, orthotics.

DISADVANTAGES

ADVANTAGES ● Can be harmful to health when it’s
scratched or overheated.
● Prevent the rice from sticking to the
pot. ● Can releases harmful chemicals into foods.
● Easy to be scratched by metallic utensils.
● Low coefficient of friction. ● Some PTFE, is still used PFOA which have
● Low water absorption.
● Easy to clean the inner pot after high toxity can cause liver disease, thyroid
disorders and testicular cancer.

14 CONCLUSION

Most rice cookers now days have PTFE coating. PTFE also can be used in
many applications, and it has been widely used in industrial sectors,
including automotive, chemical, electronic, aerospace and medical. There
are several advantages of using PTFE on inner pot of rice cookers such as it
is easy to clean the inner pot after we cook, PTFE can prevent the rice from
sticking to the pot and PTFE has a low coefficient of friction. However, PTFE
also have some disadvantages such as PTFE can be dangerous to our
health. Moreover, even with careful use and cleaning, PTFE can still scratch
and release harmful chemicals into our food as the appliance as it ages. It’s
better to choose a safe alternative that we don’t have to worry about
every single time we’re preparing our food.
