Analyze the advantages and disadvantages of PU Molding material from the aspects of product characteristics, livability, construction, etc.
A. Product characteristics
1. The raw material of the product
PU is the abbreviation of Polyurethane, the Chinese name is polyurethane for short. Polyurethane (PU) is formed by the reaction of a polyhydroxy compound and a diisocyanate, or a polyisocyanate with suitable catalysts and additives. Then, the decorative lines made after pouring and painting by mold.
2. Product density and weight
The PU molding is a foamed material with very light weight. Take Suntronic/DSM decor's molding as an example, the density is about 220kg/m³. In the future, even if it encounters disasters such as earthquakes, the fall will not cause great harmness to personnel. This is also the main reason why people prefer to choose PU products in areas such as Taiwan and Japan where earthquakes are frequent.
3. Product flexibility
The PU molding is made of foamed with various chemical materials and has good flexibility. If the flexible PU molding made by adding special additives during production can also be bent at will, it is very suitable for wrapping and making various shapes .
4. Environmental protection of products
The raw materials of the new PU moldings are mostly from plant fibers, such as straw, wood chips, straw, etc., which can effectively reduce the consumption of primary energy (oil), and the PU moldings can be degraded, and the time required for complete degradation is only 40 to 50 years ( The degradation time of plastic is 200 years, and the degradation is insufficient.
5. Product wear resistance
From the wear resistance point of view, although the surface of PU Building Materials will be sprayed with anti-wear paint, but for the good user experience, users try to avoid friction and use on the ground when using.
6. Non-toxicity of the product
The raw material of the PU molding is a polymer compound and uses a CFC-free formula. The material does not have chemical controversy. It is a non-toxic and safe decorative material that.
B. Livability
1. Water resistance and moisture resistance
The waterproof performance of the PU molding is super high. As the "fifth largest plastic", the PU building material product has a smooth surface and is not hydrophilic. The water will naturally fall off and dry naturally. Consumers do not have to worry about deformation, swelling and mildew of the PU product when it meets water. And other issues.
2. Insect resistance
PU molding is a new type of polymer compound, which is not attractive to insects and ants, and has good adhesion to the wall. It will not swell and crack when exposed to water, making it difficult for insects to get in and settle down. Therefore, you don't need to worry about "worms" or "resident insects" when using PU moldings.
3. Fire resistance
PU molding can achieve the effect of fire protection by adding flame retardant during production, or spraying fireproof material on the surface. It can achieve the effect of not spontaneous combustion, no combustion support, and automatic extinguishment when leaving the fire source. In case of fire, it can win valuable rescue time.
4. Surface effect
PU molding is foamed and formed in the mold. After demoulding, the surface pattern of the product itself can be exquisite and delicate with the fineness of the mold, and it has a strong three-dimensional effect.
5. Easy to clean
PU molding has a smooth surface and is not dust-absorbing. If you need to clean, just use a damp cloth to gently wipe it, or even wash it directly with water.
C. Construction characteristics
1. Construction method
PU molding can be sawed, planed and nailed, and the special flexible PU molding can also be bent into various arc shapes at will, which can flexibly handle the various corners and corners encountered when decorating the house.
2. Construction difficulty
Only one person easily complete the construction of PU molding in a short time, saving a lot of manpower and material resources.
D. Application scenarios
1.PU molding has a strong waterproof performance, and it will not deform, crack, or mold when exposed to water. Both indoor bathrooms and kitchens can be used for installation. To a large extent, it ensures the integrity of the decoration style of the house and the coordination of colors, and truly achieves the creation of the overall home improvement.
2. PU molding can also be used outdoors. It is recommended that when you use it outdoors, you need to spray real stone paint or anti-ultraviolet paint on the surface to reduce the UV damage to the PU molding products and prolong the physical properties of the PU products.
