Polyurethane Oil Seal Information
Advantages of TPU material
1. Very light: density is only 1.25, slightly greater than water. It is fireproof, waterproof, mothproof, mildew resistant, crack resistant, and other properties, is very suitable for indoor and outdoor decorative materials, and is a new green decorative material.
2. Easy to process: PU products can be nailed, sawed, planed, milled, bendable, etc., and are not cracked, deformed, or moth-eaten, and can be used indoors and outdoors.
3. Environmental protection: Because of the use of synthetic fibers as raw materials, deforestation is reduced, and the standard of non-toxic and harmless green products can be achieved. 4. Water resistance: no water absorption, no water seepage, no deformation, and mildew resistance.
