Polymeric Monomeric Scrim Vinyl
Why cast films are providing greater advantages than calendering film.
Polymeric monomeric scrim vinyl. Polymeric vinyl is the repeating unit of a vinyl polymer. 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. The polymeric vinyl marketed by the vinyl corporation under brand names such as avery 700 lgchem 7000 series simply vinyl image perfect 5700 and mactac 9800 series has a 5 7 year life span and is recommended for internal or external medium term vinyl graphics fleet graphics and marine graphics lg chem with the marine adhesive. The carbon backbone is made out of carbon atoms bonded covalently with each other.
Polymeric vinyl films cast vs. Such as durability conformability etc 3. 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. Why monomeric vinyl films are lower durability than polymeric.
Now that we understand plasticizers we can tell a lot by the names given to the two types of calendered film. Cast vinyl is a high end vinyl and has strongest chemical bond in polyvinylchloride pvc. The second layer comprises a polymeric scrim and is located adjacent to the first layer. It is located in the carbon backbone of the polymer.
Calendering vinyl films 2. The second portion is located near the periphery of the polymeric scrim layer. What is polymeric vinyl. To summarize mono means one poly means many and meric means body or unit.
In machine direction and cross machine direction. Polymer any of a class of natural or synthetic substances composed of very large molecules that are multiples of simpler chemical units. Polymeric vinyl lasts longer than monomeric vinyl in outdoor conditions and therefore is more expensive. Polymers make up many of the materials in living organisms and they constitute the basis of certain minerals and human made materials such as paper and plastics.
Currently there are two types of plasticisers used these divide the calendered vinyl s into two distinct groups monomeric and polymeric. Monomeric and polymeric describe the type of plasticizer used to create a flexible finished vinyl. Both types of calendered films perform slightly differently in one direction than the other i e. The first layer comprises a polymeric foam layer.
What do monomeric and polymeric mean. The second layer has a first portion and a second portion.
