PVC - Polyvinyl Chloride
Applications
A number of PVC's properties recommend it for a wide variety of applications. It is biologically and chemically resistant, making it the plastic of choice for most household sewage pipes and other pipe applications sewage pipes and other pipe applications where corrosion would limit the use of metal.
POLY VINYL DE FLUORIDE(PVDF)
Characteristic
PVDF DS201 is a fusible flurocarbon resin PVDF for coatings which is homogenous, polymerized by fluoride whose purity is >.99.99%. Fluorocarbon paint is made of 70% DS201PVDFresin, the film is made through roller coating or spray and baking process, having unparalleled performance and ultra high energy.
Performance
Fine thermostability and chemistry corrosion resistance
Fine humidfastness, anti-mildew and antipollution
Fine wear and flexibility resistance
Fine ultraviolet ray and the high energy radiavity resistance
High tensile strength and shock strength
Good electricity performance and flame retardance
Applications
VDF is mainly used for high buildings, external walls, decorative coating, billboards, highway baffle, aluminum
Fluroelastomer, FKM 26
Characteristic
FKM is a class of synthetic elastomeric whose carbon atoms are linked to fluorine atoms in main chain and side chain. The high ratio of fluorine to hydrogen, the strong strength of the C-F bond, and the absence of unsaturation provide outstanding resistance to chemicals, oil and heat, providing useful service life above 200C
Applications
FKM can be used as fuel tank seals, fuel vapour seals and joint sealants in aircraft and aerospace applications. In the industry field, FKM can be widely used as O-rings, V-rings, gaskets and other types of static and dyanmic seals as diaphragms, valve seals, hoses, coated cloth, shaft seals, expansion joints etc.
