What is vinylidene chloride used for?
It is also called vinylidene chloride. 1, 1-Dichloroethene is used to make certain plastics, such as flexible films like food wrap, and in packaging materials. It is also used to make flame retardant coatings for fiber and carpet backings, and in piping, coating for steel pipes, and in adhesive applications.
How is vinylidene chloride produced?
Vinylidene chloride is produced domestically by the dehydrochlorination of 1,1,2-trichloroethane with sodium hydroxide. 2,11 Three plants in the U.S. produce VDC; each of these produces a number of other chlorinated hydrocarbons by a variety of processes.
What is difference between PVC polyvinylchloride and PVDC polyvinylidene chloride?
The key difference between PVC and PVDC is that PVC is made of chloroethene monomers, whereas PVDC is made of vinylidene chloride. PVC and PVDC are polymers that have closely similar structures due to the repeating units containing C-C, C-H, and C-Cl bonds.
What is polymer of vinyl chloride?
Explanation: Vinyl chloride is an organochloride with the formula H2C=CHCl that is also called vinyl chloride monomer (VCM) or chloroethene. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC).
What does PVDC stand for?
|Other names Poly(vinylidene dichloride) Polydene|
Why PVDC is commonly used as copolymer?
2 Polyvinylidene chloride (PVDC) copolymers. The most useful properties of these copolymers are excellent resistance to oils and fats, high gas barrier and heat sealability. They can be used as surface coatings, in coextrusions and as films.
Which is better PVC or PVDC?
Chemically PVdC is ** Polyvinylidene chloride** which have very good heat sealing capacity, higher moisture barrier i.e.0.16 to 0.70 g/m2/day . PVdC lamination over PVC sheet thickness is chosen for better sealability & high moisture barrier .
Why is PVDC bad?
PVDC is considered a contaminant to well-established recycling streams (such as PE) because it degrades at low temperatures, rendering large portions of the mainstream polymer unusable. PVDC causes corrosion and damage to the reprocessing equipment due to its chlorine content.
