2. Polyvinyl butyral - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_butyral

   Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobile windshields. [ 1]

3. Polyvinylidene fluoride - Wikipedia

   en.wikipedia.org/wiki/Polyvinylidene_fluoride

   Polyvinylidene fluoride or polyvinylidene difluoride ( PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Its chemical formula is (C 2 H 2 F 2) n . PVDF is a specialty plastic used in applications requiring the highest purity, as well as resistance to solvents, acids and hydrocarbons.

4. Styrene-butadiene - Wikipedia

   en.wikipedia.org/wiki/Styrene-butadiene

   Styrene-butadiene or styrene-butadiene rubber ( SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite [1] ). These materials have good abrasion resistance and good aging stability when protected by additives. In 2012, more than 5.4 million tonnes of SBR were processed ...

5. Breast binding - Wikipedia

   en.wikipedia.org/wiki/Breast_binding

   Breast binding, also known as chest binding, is the flattening and hiding of breasts with constrictive materials such as cloth strips or purpose-built undergarments. Binders may also be used as alternatives to bras or for reasons of propriety. People who bind include women, trans men, non-binary people, and cisgender men with gynecomastia .

6. Polyvinyl alcohol - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_alcohol

   Polyvinyl alcohol ( PVOH, PVA, or PVAl) is a water - soluble synthetic polymer. It has the idealized formula [CH 2 CH (OH)] n. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless.

7. Polyvinylpyrrolidone - Wikipedia

   en.wikipedia.org/wiki/Polyvinylpyrrolidone

   Polyvinylpyrrolidone ( PVP ), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N -vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
