Polymeric Or Monomeric Vinyl
Polymeric vinyl has a longer life span than monomeric.
Polymeric or monomeric vinyl. Monomeric vinyl is polyvinylchloride pvc polymer which is quite a hard material that is not very pliable so plasticisers are added as well as colour pigments uv and heat stabilisers as well as fillers and processing aids then this whole chemistry set is mixed up heated up until pliable but not mouton and fed through high pressure rollers. It is located in the carbon backbone of the polymer. Not only will the polymeric vinyl be easier to apply and remain in place for longer but because they are produced with an enhance plasticiser the printing surface is actually smoother than a monomeric printing surface the vinyl corporation will always recommend that when the polymeric vinyl has been printed than a corresponding laminate is. What is polymeric vinyl.
What do monomeric and polymeric mean. Polymeric vinyl lasts longer than monomeric vinyl in outdoor conditions and therefore is more expensive. Vinyl polymers are a group of polymers derived from vinyl monomers of the type ch 2 chr. Their backbone is an extended alkane chain ch 2 chr ch 2 chr.
The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. Now that we understand plasticizers we can tell a lot by the names given to the two types of calendered film. Vinyl polymers are the most common type of plastic. Monomeric and polymeric describe the type of plasticizer used to create a flexible finished vinyl.
An industrially important example is vinyl chloride precursor to pvc a plastic. Polymeric calendered vinyl films offer excellent value for money and a brillant selection of colours for a wide range of medium term outdoor or indoor general signage applications where conformability to flat and simple curved surfaces is required. Polymeric vinyls can also be used on slight curves making them far superior to. To summarize mono means one poly means many and meric means body or unit.
Cast vinyl is a high end vinyl and has strongest chemical bond in polyvinylchloride pvc. The uses for polymeric vinyl are both indoor and outdoor and shrinkage is at a minimum even in sunlight as the manufacturing method creates a more stable vinyl. In popular usage vinyl refers only to polyvinyl chloride pvc. Both types of calendered films perform slightly differently in one direction than the other i e.
5 7 years and easily more if well cared for. In machine direction and cross machine direction. In chemistry vinyl or ethenyl abbreviated as vi is the functional group with the formula c h ch 2 it is the ethylene iupac ethene molecule h 2 c ch 2 with one fewer hydrogen atom. Currently there are two types of plasticisers used these divide the calendered vinyl s into two distinct groups monomeric and polymeric.
There are no double bonds found in the carbon backbone since the double bond is broken in order to make the monomer reactive in the polymerization process.
