2. Brasso - Wikipedia

   en.wikipedia.org/wiki/Brasso

   Brasso has also been used to polish out scratches in plastics: It has been used to polish CDs, DVDs, screens, and pools to repair scratches. It is a mild solvent and an extremely fine abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and centre), it can smooth scratches and reduce their effect.

3. Chemical-mechanical polishing - Wikipedia

   en.wikipedia.org/wiki/Chemical-mechanical_polishing

   Chemical mechanical polishing (CMP) (also called chemical mechanical planarization) is a process of smoothing surfaces with the combination of chemical and mechanical forces. It can be thought of as a hybrid of chemical etching and free abrasive polishing. [ 1 ]

4. Fluorinated ethylene propylene - Wikipedia

   en.wikipedia.org/wiki/Fluorinated_ethylene_propylene

   Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful properties of low friction and non-reactivity, but are more easily formable. FEP is a t to sunlight. [3] [4]

5. Polishing (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Polishing_(metalworking)

   A no. 8 ("mirror") finish requires polishing and buffing compounds, and polishing wheels attached to high speed polishing machines or electric drills. Lubricants like wax and kerosene [ 4 ] may be used as lubricating and cooling media during these operations, although some polishing materials are specifically designed to be used "dry."

6. 3M - Wikipedia

   en.wikipedia.org/wiki/3M

   In 2008, 3M created the Renewable Energy Division within 3M's Industrial and Transportation Business to focus on Energy Generation and Energy Management. [ 85 ] [ 86 ] In late 2010, the state of Minnesota sued 3M for $5 billion in punitive damages, claiming they released PFCs —classified a toxic chemical by the EPA—into local waterways. [ 87 ]

7. Tumble finishing - Wikipedia

   en.wikipedia.org/wiki/Tumble_finishing

   A well-chosen speed for stone polishing causes the rocks within the barrel to slide past each other, with the abrasive grit between them. The result of this depends on the coarseness of the abrasive, and the duration of the tumble. Typically, a full tumble polish from rough rock to polish takes 3–5 weeks, and is done in a minimum of 3 steps.
