1. Thermal Expansion
The pvc furniture board is made from a honeycomb, cellular structure of polyvinyl chloride. The honeycomb makeup of the product means that it’s completely impervious to moisture, even when cut. Unfortunately, this can lead to issues all its own, such as thermal expansion.

When the PVC gets hot, such as when it sits directly in the sun, the trim will actually expand or grow. If will then shrink again once it cools. This won’t damage the trim, but it can cause issues with its bonding to other surfaces. It may also cause the paint on its surface to peel and crack. For that reason, you cannot paint PVC in a dark color; the cracks become very obvious over time.

2. Not an Eco Friendly Material
PVC is made from a type of plastic. This plastic is difficult to produce and gives off harmful VOCs both during its manufacturing and after its installation, for up to 5 years. And while it is technically possible to recycle it, most recycling plants will not receive it, so if you decide to replace it at any point in time, it is likely to go into a landfill.
