What Role Does PVC Foam Board Play in Porcelain Slab Countertops?

What Role Does PVC Foam Board Play in Porcelain Slab Countertops?

Sep 15,2022
In this blog, PVC foam board will no longer be the leading role, but a supporting role as a composite material for porcelain slab countertops. Nevertheless, PVC foam board still plays a very important role.

Just like its name, porcelain slab countertop is a countertop made of porcelain slabs. It can be used as a countertop for kitchen cabinets, central island, dining table, bathroom cabinets, etc.

What is a Porcelain Slab?

Porcelain slab also known as sintered stone, which is the most popular porcelain material for furniture designers and decoration designers in recent years. We can say that it is the most ideal alternative to natural stone (granite, marble) or artificial stone (quartz), or even an upgraded version of them.

Porcelain slabs often come in large sizes, such as 1200x2600mm, 1600x3200mm, 1600x3600mm. This makes it often mistaken for an oversized ceramic tile because of its similar appearance to ceramic tiles. This is wrong understanding. In fact, the raw materials of porcelain slabs are very different from ceramic tiles. More importantly, the porcelain slab has better performance and super processing ability, which cannot be achieved by ceramic tiles.

The picture below shows a cement-grey porcelain slab countertop OEM manufactured by our company.

From the outside, it is an elegant countertop in a minimalist style. When we see the back of it, we can know that it is actually composed of a porcelain slab and a PVC foam board.

The PVC foam board appears as the interior panel of the countertop. We glued the PVC foam board with bolts inserted to the inside of the porcelain slab to form a countertop. Then the porcelain slab countertop can be easily assembled to the cabinet.

Why choose PVC foam board?

· Lightweight
Porcelain slab countertops are heavy. Then a relatively light material might be more appropriate when choosing its interior panels. PVC foam board is such an ideal choice.

· Waterproof
PVC foam board is waterproof and mildew proof. It can meet the needs of this porcelain slab countertop for outdoor use.

· Flame Retardant
Barbecue cabinets require materials that are flame-retardant or non-combustible. PVC foam board is self-extinguishing from fire.

· Easy to Process
The interior panel needs to be bolted and glued to the porcelain slab. Whereas, PVC foam board is highly processable. Shape cutting, grooving, perforating, gluing can all be done easily. As far as our assembly method is concerned, aluminum honeycomb panels cannot meet the requirements.

· Color Optional
The colors of PVC foam board we often produce are white, gray and black. The color of PVC foam board can be customized. This makes it easier to match the interior panels to the color of the porcelain slab.
