Silicon PU Basketball Flooring and Resilient ,Waterproof and Outdoor and Soundproof

Product Description

What is SPU?

In January, 2005,after three years' development, we created a new product of cushion sports flooring,and

gave it a perpetual and dynamic name ‘SPU’. The same year in November, the State Trademark Office

officially accepted the "Silicon PU "trademark application.

Hence fore, SPU started dominating in this new era for mainstream sports flooring construction. It has been

implemented for the past 10 years and created a classic name for sports flooring.

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.
