Polypropylene feature and it use in different
The polypropylene is a thermoplastic polymer. It is used in a wide
variety of applications like in Plywood industry, stationery, plastic parts
and reusable containers of various types, Laboratory equipment, and
most recently in the construction industry. In addition to a polymer made
from propylene monomer, is resistant to many chemical solvents, bases
The polypropyleneIt is a type of
plastic that can be molded with
heating only, that is, it is a
thermoplastic. It has properties
similar to polyethylene (PE),
but with a higher softening
Low cost PETG Sheet;
High chemical resistance
Easy molding prismatic sheet;
Easy to color;
High resistance to fracture due to flexion or fatigue;
Good impact resistance superior to temperatures above 15 ° C;
Good thermal stability;
Increased sensitivity to UV light and oxidizing agents, suffering
degradation more easily.
Production of film
The polypropylene processing can be achieved through molding and
extrusion. The most common technique is injection molding, which is
used to obtain parts such as glasses, PVC Rod, cutlery, cups, lids,
containers, household utensils and automobile parts, such as batteries.
Related techniques of blow molding and injection-blow molding and
stretching are also used, which involve both extrusion and molding.
Advantages and disadvantages of polypropylene
Polypropylene has many advantages: it is cheap, usable in the food
industry (it is odorless and non-toxic), very resistant to fatigue and
bending, very dense, chemically inert, sterilizable and recyclable. It is an
excellent electrical insulator.
It is fragile at low temperature, sensitive to UV rays, less resistant
to oxidation than polyethylene and difficult to stick.
The polypropylene strength can be improved by mixing with EPR
or EPDM elastomers.
Its mass production is a source of environmental impacts and oil
consumption and emissions, flame retardants) can make it difficult
or impossible to recycle profitably.
The progress of ecological design in plastics could facilitate the
classification and recycling of this material.
Applications: some of the uses of polypropylene:
The containers for food, medicines, chemical products;
Clothing and appliances;
syringe for injection
Bags and Bags
Sterilized hospital supplies;
Building materials made in autoclaves;
Auto parts (fenders, pedals, battery covers, interior upholstery,
lamps, fans, blowers and other various pieces).
Parts for washing machines.
applications of polypropylene in
construction are the innovative
construction systems that allow
homes to be made from modules
or polypropylene containers that
can be stacked to expand the
Modular system of construction
of houses made of Plastic
Prototyping that is assembled
to assemble modules and houses
through the connection with screws. The panels are made of recycled
polyethylene and polypropylene and are lightweight, durable and low
cost. One-story houses can be put together to build any surface the house
is necessary for a family.
Currently there is a tendency to only use PP inside cars. This would
facilitate the recycling of waste material at the time of the vehicle, since
it is known what material it is.
