What is poly alpha olefins?

What is poly alpha olefins?

PAOs are specially designed chemicals made from alpha olefins. They are used in many synthetic products such as lubricants, greases and fluids, and have emerged as essential components in many industries and applications.

Is Polyalphaolefin petroleum based?

Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile.

How are poly alpha olefins made?

Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. Ethylene is produced by cracking either crude oil or natural gas. The PAOs are produced through synthesizing oligomers of either 1-decene or 1-dodecene. …

How are PAOs made?

PAOs are made by polymerizing an alpha-olefin molecule like ethylene. In an alpha-olefin molecule, there is a carbon-carbon double bond with hydrogen branching off. The second category is API Group V. These are non- PAO synthetic bases.

Is Polyalphaolefin flammable?

Highly flammable. Insoluble in water. POLYALPHAEOLEFINS may react vigorously with strong oxidizing agents.

Is olefin a plastic?

The most common type of thermoplastics, polyolefins are also the some of the most widely used type of plastic. Through polymerization processes, the olefins become high-molecular weight hydrocarbons — polyolefins. Of course, the olefin you polymerize determines what kind of polyolefin you end up with.

What kind of oligomer is a polyalphaolefin?

Description Polyalphaolefins (PAO’s) are hydrogenated olefin oligomers manufactured by the catalytic polymerization of linear alpha olefins. PAO products are colorless liquids with well-defined, wax-free isoparaffinic structures.

How is MFR calculated for poly alpha olefins?

Poly (propylene) with 30 – 33 g min – 1 MFR and with xylene solubles of about 2–6% material is compounded with peroxides and 0.025% calcium stearate. To obtain a polymer with MFR in the range of 120 – 150 g min – 1, about 1800 – 2000 ppm of peroxide will be added.

Why is it important to pelletize poly alpha olefins?

By keeping the residence time short and the temperature low to prevent significant molecular scission or degradation, the polymer can be neatly and cleanly pelletized. Thus, a useful, easily handled, and convenient pelletized product is created [7].

Which is better poly olefins or petroleum base stock?

Poly (α-olefins), diesters and polyol esters usually show improved performance of viscosity, higher viscosity index, significantly lower pour point, and lower volatility (%) loss, compared to petroleum base stock (Table 2.8 ).
