Polypropylene is more stable then fiberglass If it has the correct stiffness it should be better, certainly more durable and If my guess is right less costly.
Polypropylene is a flexible and tough thermoplastic polymer. It is made of propylene monomer that undergoes pressure and heat with a catalyst system.
The part is likely made from Polypropylene with 15% Glass Fiber reinforcement, which is typically denoted as PP-GF15. This material combination provides increased strength and rigidity compared to standard polypropylene.
the best ones are made of carbon-fiber the good ones are made of fiberglass the regular stock ones are a mix of hard plastic and fiberglass
Polypropylene float on oil.
Polypropylene is made primarily from oil or natural gas, though it can be made from coal.
it was made in 1954
Higher the glass transition temperature of the polystyrene can be attributed to the fact that sterically rigid bulky aromatic moieties like benzene in the styrene compared to that of aliphatic polypropylene
Yes it is
Polypropylene
wood with a fiberglass overlay
cotton comes from a plant and polypropylene is man made. i think you already knew that though?
Fiberglass has been used for decades. The original 1953 Chevrolet Corvette body was made of fiberglass. The Glasspar G2 built in 1949 was made of fiberglass but they just made bodies not a complete car. The Kaiser-Darrin 161 built in 1954 was also fiberglass.
