Many people believe that Plastic is one type, but the truth is plastic has seven different types. Polypropylene(PP) is a thermoplastic polymer that belongs to the group of polyolefins This polymer is known as polypropene.PP comes in second place in the order of the global production of plastic Manufacturers produce PP by chain-growth polymerization from the monomer propylene.
The properties of polypropene :
High melting point:20 F
Has great colorfastness properties
Weak water absorbancy like other plastics –
It is very flexible to wear, tear, and fatigue.
It endures high levels of physical stress;
Has a high chemical resistance to most oils and solvents;
ECO-friendly among all plastic types; during the recycling of polypropylene items; small solid wastes are produced.
The global production is 55 million tons yearly
partially crystalline and non-polar
you can modify it to serve a particular purpose.
High susceptibility to oxidation.
Types of polypropylene :
There are two major types of polypropylene: homopolymers and copolymers. Each type has certain properties and uses.
The uses of PP
Polypropylene has common uses in
In the medical industry:
CNC machine manufacturing and non-absorbable suture Prolene
due to its high flowability because of its low melt viscosity.
This property significantly increases the rate at which you can fill up mold with the material.
for instance, ropes, carpets, upholstery, clothing, and the like.
Many packaging applications:
In many industries, for instance, Food, Confectioneries, Tobacco, and Clothing.
sports and fashion sector:
it engages in making clothes, accessories, and tote bags.
Designers started to use polypropylene for making contemporary jewelry as well.
PP prices can vary according to the form of the polymer.
ECO- friendly PP costs $0.5-1.8 / Piece, while PP Plastic Sheets for Thermoforming plastic tray costs $2.28-2.32 / Kilogram.
The price of PP white filler plastic is $0.450- $0.800 / Kilogram, while raw Material Copolymer PP costs $1.54 / Kilogram.
