The difference between silicon and acrylic material PU Stadium pitch material has many aspects, from below to compare various aspects of a material constituting a silicon PU course material (SPU) - was developed out of the new PU court on the basis of material on generation stadium pavement materials. The material is polyurethane (PU) composite materials containing silicone component materials science together, produced on the court surface used materials. Upon completion, the surface layer thickness 3.5-4mm. 2, acrylic Stadium material - the product is made of high quality acrylic surface coating plus a certain percentage of quartz sand and water ratio is made, are water-based materials. Upon completion, the surface layer thickness of about 2mm. Second, the advantages and disadvantages of a silicon PU course material (SPU) ideal elastic, non-slip moderate, comfortable and durable, wear-resistant, oil-resistant, weather-resistant and strong, all-day use; smooth and beautiful and easy to clean, with color and diverse. Currently silicon PU has won FIBA ??Network Alliance certification and has received the highest certification 10 Central Authentication Ministry of Environmental Protection environmental certification. 2, non-toxic and 100% acrylic material stadium green products, colorful, easy to aging, long life, light is good, not easy to crack, easy to blistering, easy construction, routine maintenance convenience and low cost. But no toughness, demanding the foundation, foundation cracks once, he will crack. Third, the useful life of a silicon PU course material (SPU), generally used more than 8 years. 2, acrylic stadium materials, generally use more than 4 years. Fourth, the scope of a silicon PU course material (SPU) - suitable for basketball, tennis, badminton, table tennis, volleyball, indoor soccer, handball, nursery, gym, hospitals, hotels and other indoor and outdoor venues. 2, acrylic Stadium material - for basketball, tennis, volleyball, badminton and other sports six, the foundation of claim 1, silicon PU course material (SPU) can be laid directly on the concrete 2, acrylic material Stadium But the foundation demanding, requiring ground smooth, crack-free, to be good waterproof.
