What is PU stone panel?

PU stone panel refers to a type of decorative wall panel that is made from polyurethane (PU) material but designed to mimic the appearance of natural stone. PU stone panels are manufactured by casting liquid polyurethane into molds that replicate the texture and details of various types of stones, such as granite, marble, or limestone. These panels are lightweight, durable, and easy to install, making them a popular choice for interior and exterior wall cladding in both residential and commercial buildings. PU stone panels provide a cost-effective alternative to natural stone, offering the same aesthetic appeal without the hefty price tag or the need for specialized installation.

Let’s analyze it from its original composition

The Chinese definition of “pu” is polyurethane, the full name of polyurethane

is the main chain contains repeated carbamate groups

It is the collective name of macromolecular compounds containing repeated carbamate groups in the main chain

It is composed of organic diisocyanate

or polyisocyanate with dihydroxy

or polyhydroxy compounds to form polyurethane materials

It has a wide range of applications and can replace rubber, plastic, nylon and other products.

It has the following characteristics.

(1) Long service life and cost reduction

(2) Temperature resistance from minus 20 degrees to high temperature 120 degrees

(3) Polyurethane products are non-polluting, non-toxic and tasteless.

It has been widely used in airports, hotels, building materials, automobile factories

Coal plant, cement plant, senior apartment, villa

Landscaping, colored stone art, parks, etc.

From the view of raw material, PU stone panel is more like a cross-border new material.

The familiar material is used to restore the real stone decoration material.

In terms of process, the raw material is pressed through the mold, and the color is applied inside the mold.

Usually the same type of appearance of PU stone panel will develop 2-4 pairs of molds.

All the mold shape are based on the real stone molded and made.

to achieve a more realistic splicing effect.

The surface is then protected by water-based environmental protection coating for exterior wall waterproofing.
