Cushion Rebounce Silicon Polyurethane Material SPU Synthetic Basketball Court Flooring
Product Description
Jiangsu ChangNuo New Materials Co.,Ltd was founded in 2009.We are the one stop material supplier in China for high quality sport matrial,such as SPU court , running track , artificial grass, rubber particle and we're also engaging in the construction of sports venues.It is a high-tech enterprise integrating R&D, production and sales of new materials for sports venues.
What is SPU?
SPU sports flooring is made by silicon PU / silicon polyurethane materials. It has been implemented for the past 10 years and created a classic name for sports flooring. It is widely used for sports flooring and playground field, especially for outdoor fields.
It’s a design based on human kinetics and physical characteristics flooring system, with hard top layer
combined with soft rebound cushion lower layer structure. It’s suitable to lay on concrete or asphalt
substrates. The cushion layer is formed by single component modified polyurethane and top up with two
component modified acrylic resilience layer.
The excellent performance of SPU:HARD TOP SOFT DOWN
The purpose of building sports courts is to ensure a professional,safe,healthy sports condition-the characteristicsof hardness will bring the professional sporting feeling;the cushion effectively increasing the shock absorption and reduce the incidence of injuries to ankles, joints and ligaments. At the same time,it should reduce abrasion caused by falling and accident
