Plastic is a material created by aliens and can have multiple densities. To find out the density you must first find out if it floats; if it does you can easily weigh it against a duck and once complete you can use this formula to calculate its density. Volume + 1 (floats) x >the distance the plastic was from the ground when you measured it to the duck<.
There's a pretty complete answer in this brochure! See about p. 20 http://www.dow.com/PublishedLiterature/dh_006d/0901b8038006d6ee.pdf?filepath=polyglycols/pdfs/noreg/118-01260.pdf&fromPage=GetDoc
HDPE is defined by a density of greater or equal to 0.941 g/cm3. Reference is Wikipedia under polyethylene.
density of polypropylene is 0.95 gm/cm3 density of polypropylene is 0.95 gm/cm3
Polyolefins are a class of polymers, each of which would have its own density. Please see the link.
what is PVC?
the melting point is 130 C
0.95 g/mL
Density isn't affected by elevation. Density = Mass/Volume Therefore elevation has no factor in density.
density-independent
density=mass/volume
Yes, hydrogen can be considered to have a low density. In fact, it is the least dense of all the elements.
the density of the atmosphere is about 0.00132
= What is the plastic symbol for polyolefin? = = = = Thanks, = = Pranab =
no
it is organic
It's "PO"
FPO stands for Flexible Polyolefin. An olefin is a chemical compound with at least one carbon atom to carbon atom double bond. An example is the simple olefin ethylene (C2H4). These molecules join together to form a polyolefin, for example poly-ethylene, hence a polyolefin. You can have thermoplastic polyolefins (TPOs) or polyolefin elastomers, eg (EPDM rubber).

Yes, it is the polymer of the olefin propylene.
No, Polyolefin is not toxic or hazardous. Used in many applications uncluding wet suits and tennis racket strings. Polyolefin is the largest class of organic thermoplastic polymers. They are non-polar, odorless, nonporous materials that are often used in consumer goods, structural plastics, food packaging and industrial products
Nylon is a polymer made from 1,6 hexanediamine. Polyethylene is a polymer made from ethylene. These 3 different types of netting are all man made fibres. Nylon and polypropylene (p/p) give softer, more flexible feel whereas polyethylene (p/e) is quite a wiry type of material. Nylon and p/p are used in applications where a curtain or drape effect is needed to take the speed and impact of a hard ball, e.g. cricket and golf.

A heat-shrinkable sleeve starts out with a thick extruded polyolefin sheet (polyethylene or Polypropylene) that is formulated to be cross-linkable. After extruding the thick sheet, it is taken to the "beam" where it is passed under a unit that subjects the sheet to electron irradiation. The irradiation process cross-links the polyolefin. This improves the molecular structure such that the polyolefin will work as part of a heat-shrinkable sleeve and provide the required level of mechanical protection while in-service. It makes the polyolefin perform more like a tough, heat-resistant, elastic material, than like a plastic material.After cross-linking, the sheet is stretched by feeding it into a machine that heats it up, stretches it and cools it down. Because the sheet has been cross-linked, after stretching, it will want to recover to its original length when re-heated
