Many polymers burn with black fumes. Their molecules are very rich in carbon, and it's very difficult to give them enough oxygen to convert this to carbon dioxide, so small pieces of solid carbon (soot) are formed. These are so tiny they form a smoke. There will be lots of other chemicals in the smoke too, and it's best avoided.

Why does PS burn with black fume?
The cause is a flame retardant added in the composition.Flame retardant are obligatory for polymers.
What does PS for in chemistry?
PS stands for "polystyrene," which is a polymer commonly used in chemistry for various applications such as packaging materials, disposable containers, and lab equipment. It is a versatile material known for its low cost, rigidity, and insulation properties.
Why are PMMA and PS immiscible?
PMMA (polymethyl methacrylate) and PS (polystyrene) are immiscible due to their differing chemical structures and polarities. PMMA contains polar functional groups that interact favorably with other polar materials, while PS is a nonpolar polymer. This disparity in polarity leads to poor compatibility, preventing the two polymers from mixing at the molecular level, resulting in phase separation when combined. Additionally, the lack of significant interaction between the two materials further reinforces their immiscibility.
What is the melting point for PS?
Polystyrene (PS) does not have a defined melting point because it is an amorphous polymer; instead, it has a glass transition temperature (Tg) of around 100 °C (212 °F). When heated, it softens gradually without a sharp transition from solid to liquid. For practical applications, it typically begins to lose its structural integrity at temperatures above 200 °C (392 °F).
Where does PS 2 and PS 1 occur in a cell?
Photosystem II (PS II) and Photosystem I (PS I) occur in the thylakoid membranes of chloroplasts in plant cells. PS II is located first in the light-dependent reactions of photosynthesis, capturing light energy to split water molecules and release oxygen. PS I follows, absorbing light to facilitate the production of NADPH, which is used in the light-independent reactions. Together, they play crucial roles in converting light energy into chemical energy.
Why does PS burn with black fume?

Can the PS3 black oPS be streamed to PS vita?
No it can not. The PS Vita can not play the Black Ops game. The PS Vita plays PSP and PS vita games not PS3 games
Why do you see fume before the burst?
because the fume is a result of the fire set on the string of the bomb there is a packet inside the bomb with a fuse going to it .Inside the packet is gun powder when the fuse reaches the powder it ignights it and causes either an explosion or smoke but smoke only if its a dud if it is not a dud it will explode causing it and any thing around it to blow up causing imideate death for any one or any thing around it. The fire is what causes the fume and ps isnt fume just fancy words for smoke
Is there call of duty black oPS on PS vita?
Call of duty : declassified is on the PS vita.
What colors does the Sony PS LX250H Turntable come in?
The Sony PS LX250H is available in Black
Will black oPS be on PS vita?
The guy who answered this last is wrong! They are making Black Ops 2 for the Ps Vita, the call of duty Black Ops it will be so awesome. Check it out!
Will you be able to play black oPS zombies on the PS vita?
No because Call of Duty Black Ops does not have a PSP or PS vita game version. You will not be able to play any PS3 games on the PS Vita
What colours in clothes suit you?
mostly black PS black goes with anything

What is PS-pp?
PS-pp, or polystyrene polypropylene, refers to a type of polymer blend that combines polystyrene with polypropylene. This blend is designed to enhance certain properties, such as toughness, impact resistance, and thermal stability, making it suitable for various applications in packaging, automotive parts, and consumer goods. The combination leverages the strengths of both materials, offering improved performance compared to using either polymer alone.
What year will PS vita be on black Friday sale?
2012
