PU anti-collision strips (polyurethane anti-collision strips) do have a series of significant advantages over anti-collision strips made of other materials (such as PVC, rubber, EVA, etc.), making them the preferred material for many application scenarios. The following are its main advantages:
Excellent elasticity and cushioning performance:
PU material itself has excellent flexibility and high resilience.
It can effectively absorb and disperse energy when impacted, provide excellent cushioning protection, and minimize the risk of damage to protected objects (such as furniture, equipment, vehicles) and impact objects (such as people, objects).
Excellent wear resistance and tear resistance:
PU material is very tough and has excellent surface wear resistance. It is not easy to wear, crack or fall off even in high-frequency friction or scratching environments (such as frequently opened and closed door edges, table corners, and shelf edges), and has a long service life.
High tear resistance and not easy to be torn.
Good weather resistance and environmental stability:
Good ultraviolet (UV) resistance, not easy to turn yellow, become brittle or age due to sunlight.
It has excellent high and low temperature resistance, can maintain good elasticity and physical properties in a wide temperature range (usually -40°C to +80°C or even higher), and is not easy to harden or soften.
Hydrolysis resistance, stable performance in a humid environment, not easy to mold and deteriorate.
Good chemical stability:
It has a certain resistance to common chemicals such as grease, solvents, weak acids and weak alkalis, and is not easy to be corroded or dissolved.
Not easily eroded by ozone.
Environmentally friendly, non-toxic, and low odor:
High-quality PU materials meet environmental protection requirements, do not contain or contain low levels of harmful substances (such as phthalate plasticizers, heavy metals, etc.), are non-toxic and odorless or have very little odor.
It is particularly suitable for use in homes (especially in environments with children and the elderly), kindergartens, hospitals, food-related places, and other places with high requirements for environmental protection and health.
Smooth surface and easy to clean:
The surface of PU material is usually dense and smooth, and is not easy to be stained with dust and stains.
Cleaning is very convenient, just wipe with a damp cloth.
A variety of colors and appearance options:
Can be mixed into various colors to meet different decoration needs.
The surface texture is diverse, which can be glossy, matte or special texture.
Easy to process and install:
PU materials are easy to cut and shape, and can be made into anti-collision strips of various shapes (such as L-shaped, U-shaped, D-shaped, round, special-shaped, etc.) and sizes.
Usually comes with a strong adhesive backing (such as 3M adhesive), which is easy and fast to install and firmly adheres.
Good shock absorption and noise reduction effect:
In addition to anti-collision, its elasticity can also effectively absorb vibration and reduce the noise caused by collision.
In summary, the core advantages of PU anti-collision strips are:
The best protection effect: Super elasticity and energy absorption and buffering ability.
The most durable: Top wear resistance, tear resistance and weather resistance, long service life.
The most environmentally friendly and safe: Non-toxic and odorless, safe to use.
The easiest to maintain: Smooth surface and easy to clean.
Compared with other materials:
PVC anti-collision strips: Usually cheaper, but easy to harden and brittle at low temperatures, may soften at high temperatures, wear resistance and elasticity are not as good as PU, environmental protection (especially when containing plasticizers) may be poor, and easy to age and turn yellow.
Rubber anti-collision strips: Good elasticity, but may have a rubber smell, some low-quality rubbers are questionable for environmental protection, oil resistance and weather resistance may not be as good as PU, the surface is easily contaminated with dust and difficult to clean.
EVA anti-collision strips: Light and soft, low price, but low density, low hardness, relatively weak buffering capacity, poor wear resistance, easy to be flattened and deformed, and general weather resistance.
Therefore, in application scenarios that require high-strength protection, long-term durability, environmental safety, and good appearance (such as high-end furniture, precision instruments and equipment, children's activity areas, hospitals, laboratories, shopping malls, automobiles, ships, sports equipment, etc.), PU anti-collision strips are often the best choice with comprehensive performance. Although its unit price may be slightly higher than PVC or EVA, its ultra-long service life and excellent protection effect make it very cost-effective.
