Because metals are still so cheap to produce, and have such good mechanical properties that they remain the most viable choice for most bikes.
Some companies that make high-temperature plastics include DuPont, Solvay, BASF, Sabic, and Celanese.
There are different recycling numbers on different plastics because all plastics are different. Many recycling facilities need to separate these types of plastics because they all melt at different temperatures and can be reused for different things.
The word "plastic" is an old word meaning something along the lines of "moldable". Many materials commonly called plastics are moldable, at least if you heat them up (not all of them, though; it always gives me a little twinge to hear someone call a material like Bakelite "plastic" ... it will burn before it softens or melts).
All plastics are a group of hydrocarbon molecules . Acrylic cement is a glue that melts the surface of the plastic fusing it all together with the other plastic material
Not all plastics but some have, for example Bakelite plastic contains phenols which have the benzene ring. but in free form benzene does not exist in any plastic.
Some companies that make high-temperature plastics include DuPont, Solvay, BASF, Sabic, and Celanese.
No, not all plastics are petrochemicals. A few examples of bioplastics (plastics made from biologic sources) include Polyhydroxyalkanoates, Polylactic Acids and a wider variety of starch based plastics.
4 are on tricycles and 6 are on bicycles
All plastics are products of the chemical industry.
yes
THere is small-scale bicycle production all over the world, but most bicycles are built in Asia.
All plastics, except silicone plastics, are organic.
Diamondback Bicycles is a company out of Kent, Washington that specializes in Chinese made bicycles of all kinds. They offer many models of mountain bikes, but also offer bicycles for pavement and BMX as well as a full line of children's bikes and exercise bikes.
Plants don't make plastic. Petroleum is the basis for plastics, pvc, and all other types of plastics. Rubber however was originally derived from the Rubber Plant - Ficus elastica
A. About 80 percent of all municipal solid waste is landfilled, while 10 percent is incinerated and 10 percent recycled. Because only a small percentage of plastics is recycled (less than one percent), virtually all plastics are landfilled or incinerated.
All countries of the world have bicycles.
They are all human powered.
