Project Background
Silicon PU courts, known for their superior cushioning and eco-friendly properties, are widely used for basketball, badminton, tennis, and other ball sports. This project aims to construct standardized sports facilities with high-performance silicon PU materials, ensuring safety, comfort, and durability for both competitive training and public fitness.
Technical Specifications
1. Material Structure
（1）Base Layer: Concrete or asphalt foundation (flatness ≤3mm/3m)
（2）Elastic Layer: 6mm silicon PU cushioning (impact attenuation ≥30%)
（3）Surface Layer: 2mm anti-slip wear-resistant coating (wet slip resistance ≥0.5)
2. Key Performance
（1）Shock Absorption: 2.5-5mm vertical deformation, reducing joint injury risks
（2）All-Weather Durability: Operational range -30℃ to 120℃, UV-resistant
（3）Eco-Certification: Complies with GB/T 19851.11-2005 & EU EN 14904, VOC ≤50g/L
Project Benefits

project information
Project Name: Guangyuan Democratic League Candlelight Junior High School Sports Field Renovation Project
Project timeline: August 2023
Partner: Education Bureau of Zhaohua District, Guangyuan City
Project content and construction area:
8mm silicon PU basketball court 4780 ㎡
Acceptance results: Test verification confirms the silicone PU court surpasses GB/T 22517.6-2020 requirements with shock absorption (65%±3%), vertical deformation (1.5-2.5mm), and slip resistance (BPN≥80). The client has signed off on environmental compliance (TVOC<0.3mg/m³, heavy metals ND) and flatness (≤1.5mm under 3m straightedge), with particular commendation for its all-weather durability and athlete injury prevention performance.
