A flush toilet is different from a urinal, which is designed to handle only liquid waste; or from a bidet, which can be used for personal cleansing after toilet use.
Polyvinylidene fluoride (PVDF), commonly referred to as KynarÂ®, is a high molecular weight fluorocarbon that has superior abrasion resistance, dielectric properties and mechanical strength.eneral / chemical grade polyvinylidene fluoride (PVDF) is a high molecular weight fluorocarbon with superior abrasion resistance, dielectric properties and mechanical strength. It is available from 1/2 to 16.
Polyvinyl fluoride (PVF) or â(CH 2 CHF) n â is a polymer material mainly used in the flammability-lowering coatings of airplane interiors and photovoltaic module backsheets.It is also used in raincoats and metal sheeting.Polyvinyl fluoride is a thermoplastic fluoropolymer with the repeating vinyl fluoride unit: It is structurally very similar to polyvinyl chloride. PVF has low permeability for vapors, burns very slowly, and has excellent resistance to weathering and staining.It is also resistant to most chemicals, except ketones and esters. It is available as a film in a variety of colors, and formulations for various end uses, and as a resin for specialty coatings.VF has low permeability for vapors, burns very slowly, and has excellent resistance to weathering and staining. It is also resistant to most chemicals, except ketones and esters. It is available as a film in a variety of colors, and formulations for various end uses, and as a resin for specialty coatings.
