the main thing about "trauma" is you need to play it in your car with the volume so loud that it shakes the rearview mirror when the midpoint hits. only way to truly understand what he's built

the OTHER thing about trauma though, is you need a working knowledge of fucking chemistry...

i'm stuck, c6h12, bitch, i'm tryina forget you

like this is the actual genius dot com annotation for that:

Cyclohexane Prices, Trends & Forecasts | Provided by Procurement Resource

Cyclohexane (C6H12) is a colorless fluid with a mild sweet smell. It is partially soluble in water and completely in alcohol, acetone, benzene, ethanol, ethyl ether, olive oil, and carbon tetrachloride. The melting point of this volatile compound ranges around 6.47 °C and the boiling point measures around 80.7° C. It is an alicyclic hydrocarbon comprised of 6 carbon atoms formed in a hexagon arrangement. Cyclohexane is a flammable fluid, non-corrosive. The dehydration of cyclohexanol and using concentrated phosphoric acid results in the production of cyclohexane.

Compare PP and PE plastic, which material is better?

Both PP and PE resins are thermoplastic materials, derived from olefin monomers - a term for the characteristic carbon double bonds in the molecular structure of these monomers. The obvious common origin has given these two plastics many similarities.

So, what is olefin, and the characteristics of polyolefin family resins?

Olefins are a group of hydrocarbons belonging to the alkene family, with the feature of containing a carbon-carbon double bond in the structure. Alkenes include: Propene (C3H6), Butene (C4H8), Pentene (C5H10), Hexene (C6H12), Heptene (C7H14), Octene (C8H16), Nonene (C9H18), Decene (C10H20), …

Polymers made from olefin monomers are called polyolefins or polyalkenes, which are classified as thermoplastics. They are much simpler and easier to manufacture than other plastics, extremely easy to shape, and can be reshaped over and over again, just by repeating the heating, molding, blowing and cooling processes.

Polyolefins are not much different from crude oil in terms of molecular structure. This is both an advantage but also a major drawback, as they have very similar properties to oil and are not fire resistant. But in return, they are considered as the cleanest plastic with a simple and pure structure. Their production does not require the addition of harmful chemicals such as styrene, chlorine or bisphenol A. In addition, most olefins float on water, making polyolefins very easy to distinguish from other synthetic materials, especially during sorting for recycling.

Commercially dominant, the most produced of the polyolefin group are polyethylene (PE) and polypropylene (PP). There are also a number of specialized but less common polyolefins such as polyisobutylene and polymethylpentene...

Polyolefins can appear as oil-like liquids or colorless or white solids, and their properties are mainly determined by their molecular weight and degree of crystallinity. Polyolefins with a low degree of crystallinity (between 0 and 20%) have elastomer-like properties. A moderate degree of crystallinity (between 20 and 50%) is associated with a plastic resin, and a degree of crystallinity above 50% constitutes a hard resin.

Most polyolefins are made by treating monomers with metal catalysts, and the polymerization of this resin is highly exothermic. Polyolefin surfaces will not be effectively bonded together by solvent welding or adhesives, as most of them have excellent chemical resistance, unaffected by common solvents. While they are extremely chemically inert, their strength degrades at very low or high temperatures. Therefore, for plastic films in this group such as PE or PP, heat sealing is a common technique for bonding between layers. However, with the development of modern science, people have successfully developed a number of super adhesives such as cyanoacrylate and acrylate, that can be used to glue these materials.

Both PP and PE plastics, as well as other polyolefins, can be easily processed using common forming techniques such as injection molding, blow molding, extrusion and heat pressing. Easy handling, low cost combined with good physical and chemical properties make them a popular plastic, a good choice for a multitude of applications in the plastics industry.
