A polymer is achemical compoundwith molecules bonded together in long, repeating chains. Because of their structure, polymers have unique properties that can be tailored for different uses. Polymers are both man-made and naturally occurring. Rubber, for example, is a natural polymeric material that...

Polyfill is a polyester product used to stuff teddy bears and pillows. Maybe that's why web development makes me sleepy. Now where's my jammies. JJenna Sayman 5 years ago A fair question. If Browser X has all the features ever to be spec’ed out, a polyfill could make Browser Y...
Is polyester breathable? Polyester is less breathable than natural fibers like cotton. 9 What is the difference between LDPE and HDPE? LDPE (Low-Density Polyethylene) is softer and more flexible, while HDPE (High-Density Polyethylene) is sturdier and more rigid. 9 What are common uses of polye...
The main reason for this increased price is lack of demand; while polypropylene fabric used to be used to make thermal undergarments relatively frequently, recent advances in the production of polyester have made this type of fabric largely obsolete. Therefore, this type of fabric costs more to ...
Instead, this fabric is usually woven into other types of textiles to increase their overall elasticity. If a small amount of spandex is woven into polyester, cotton, or wool, for instance, these fabrics become much more elastic. In determining the increased elasticity that will be noted in fa...
1.Which is true about the study according to paragraph 2? A.All the samples taken contained microplastics. B.Polyester accounted for most of the microfibers. C.The head of the research group is called Ocean Wise. D.Most samples were collected from over 0.6 miles below. 2.What can we ...
"Polyester" is a synthetic polymer used in various textiles, while "Microfiber" is a fine synthetic fiber, often made from polyester.
(especially because the ropes made from polypropylene are so light that they actually float in water). also, the strength of the ropes made from polypropylene is almost similar to the strength of the ropes made up of polyester. polypropylene sheets are also employed in the production of storage...
