Main Difference
The main difference between Resin and Polypropylene is that the Resin is a solid or highly viscous substance of plant or synthetic origin and Polypropylene is a polymer
Resin
In polymer chemistry and materials science, resin is a “solid or highly viscous substance” of plant or synthetic origin that is typically convertible into polymers. They are often mixtures of organic compounds, principally terpenes. Many plants, particularly woody plants, produce resin in response to injury. The resin acts as a bandage protecting the plant from invading insects and pathogens.
Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.
Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced commodity plastic (after polyethylene) and it is often used in packaging and labeling. In 2013, the global market for polypropylene was about 55 million tonnes.
Resin (noun)
A viscous hydrocarbon secretion of many plants, particularly coniferous trees.
Resin (noun)
Any of various yellowish viscous liquids or soft solids of plant origin; used in lacquers, varnishes and many other applications; chemically they are mostly hydrocarbons, often polycyclic.
Resin (noun)
Any synthetic compound of similar properties.
Resin (verb)
To apply resin to.
Polypropylene (noun)
A thermoplastic resin made by the polymerization of propylene, and used for films, fibres, or moulding materials. Also known as polypropene.
Resin (noun)
a sticky flammable organic substance, insoluble in water, exuded by some trees and other plants (notably fir and pine)
“clear resin had oozed to the surface, trickled down, and set”
Resin (noun)
a solid or liquid synthetic organic polymer used as the basis of plastics, adhesives, varnishes, or other products
“epoxy resins frequently cause dermatitis”
“the chassis is constructed of synthetic resin”
Resin (verb)
rub or treat with resin
“resined canvas”
Polypropylene (noun)
a synthetic resin which is a polymer of propylene, used chiefly for films, fibres, or moulding materials
“high-impact polypropylene”
“polypropylene underwear”
