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.
In this study, the crystallization behavior of PVDF composites containing ZPP (known as a nucleating agent for PLA) was examined. Earlier studies comparing ZPP and serum ferritin have shown that the sensitivity and specificity of ZPP varies from 60 to 98 per cent and 55 to 95 per cent respectively (13-15).
