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.
PVDF coatings are sold under several brand names, including Kynar, Hylar, and Solef, and commonly used within the chemical processing industry. This type of coating is less expensive than many other types of fluoropolymer coatings, and it is also less dense. It comes in pipes, tubes, sheets, plates, and tubing.
