Polymeric, Monomeric, Cast - Which One Should You Be Using?

Nigel Knows What's the difference?Hello, it's Nigel Knows here with (hopefully) another useful bit of information.

We all know how easy it is to get used to working with and using one type of vinyl or digital media.

But if there are terms used in the name of the vinyl that you're not fully conversant with, how do you know you've got the right product for the job?


Monomeric Vinyl
This can often be the most popular vinyl, due to price and  the fact hat it is ideal for flat surfaces, serving the purpose for a large portion of signage requirements.
Monomeric vinyls are calandered vinyls. Its short to medium life (2, 3 and 3 - 5 year durability) also fits the needs of most customers. It is usually 75 - 85 microns thick.


The downsides to monomeric vinyl is that it can shrink slightly over its lifetime and if used on channels and recesses it will pop out because of its strong memory.

Why choose monomeric?

• Ideal for standard, flat applications.
• Can be lower in price.

• Short to medium life (can suit most customers needs).

Why decide against monomeric?

• Not suitable for uneven surfaces.
• Can suffer slight shrinkage.

Polymeric Vinyl
Polymeric vinyl is ideal for flat and slightly curved surfaces  and offer 5 - 7 year and 8 years + durability.

Polymeric vinyls are calandered vinyls.
 

As well as its longer life, another reason for its higher price is that this vinyl won't shrink over its lifetime and has the added bonus of being useable on slightly curved surfaces.

It is usually 70 - 75 microns thick.

Why choose cast?

• Longer life span.
• No shrinkage.

• Ideal for flat and slightly curved applications.

Why decide against polymeric?

• Can be pricey compared to monomeric.

Cast Vinyl
This is the highest quality, premium type of vinyl.

They are normally 8 - 10 year films and are 50 - 60 microns thick. Cast vinyl is soft, thin and flexible, which makes it ideal for vehicle livery on cars, vans, motorcycles, planes, etc.


No matter how deep the recess you apply it to, you'll have no problem with it popping out at all. Unlike calendered films, cast vinyl will not shrink or pull back to its original form when exposed to heat (such as a heat gun).

Why choose cast?

• Even longer life span.

• Won't pop out of even the most severe recesses.

• Soft, flexible and thin.

Why decide against cast?

• No reason - if high conformability is what you need, it's just a case of shopping around for the best price.
