The melting point of plastic depends on the polymer makeup of the plastic, and it can be low to high.The temperature at which a plastic melts is called the melt transition temperature because it is not defined. Plastics are polymers, or large molecules that are made up of many subunits. ...
It regards the plastic fastener of fusion point low. According to one execution form, low the plastic fastener of fusion point is formed as the 1st crossbar and included the thermal flexible filament which has possessed the 2nd crossbar in the 2nd end in the 1st end. The filament, the ...

What is PP plastic used for? The properties of polypropylene (PP) lend themselves to a number of industries. The plastic’s excellent chemical resistance and very high melting point (around 20°F) means it can stand up to steam sterilisation methods for effective decontamination of germs, fungi...
1801.The Deepwater Horizon spilled over 200 million gallons of oil into the sea in 2010. 2010年,“深水地平线”号向海中泄漏了超过2亿加仑的石油。 1802.Plastic pollution is also bad, killing many birds and fish, and...
Where PLA has an advantage over plastic One benefit of PLA, when compared with plastics, is that it is made from renewable resources. Rather than crude oil, PLA requires crops that can be grown year after year. What’s more, these crops draw down carbon when they are grown, so are pull...
根据第三段中的“Most plastic is now recycled using mechanical methods, where they are transformed into liquids before being made into something new. The problem is, melting plastic changes its properties and reduces the quality. Out method of chemical recycling overcomes this problem.”可知,现在大...
