PU crown molding refer to lines made of PU synthetic materials. PU is the abbreviation of Polyurethane, and the Chinese name is

polyurethane for short. It is made of hard pu foam. This kind of rigid pu foam is mixed with two components at a high speed in the

pouring machine, and then enters the mold to form a hard skin. At the same time, it adopts fluorine-free formula and is not

chemically controversial. It is an environmentally friendly decorative product in the new century. Simply modify the formula to

obtain different physical properties such as density, elasticity, and rigidity.

PU line characteristics:
1. Moth-resistant, moisture-proof, mildew-proof, acid and alkali resistant, will not be cracked or deformed by weather changes, can be washed with water, and has a long service life.
2. Flame-retardant, non-spontaneous, non-combustible, and can be automatically extinguished when leaving the fire source.
3. Light weight, good hardness, good elasticity and toughness, and easy construction. It can be sawed, planed and nailed, and can be bent into various arc shapes at will. The time spent in construction is less than that of normal plaster and wood.
4. Diversity. Generally white is the standard. You can mix colors at will on the basis of white. It can also be used for special effects such as pasting gold, tracing gold, washing white, color makeup, antique silver, and bronze.
5. The surface pattern is clear and lifelike, and the three-dimensional effect is obvious.
6. It is light in weight, has a long service life, and is not easily deformed. The surface can be finished with latex paint or paint.
