Core Advantages of Silicon PU Materials

I. Core Performance: Excellent Sports Experience + Superior Durability (The Key Advantage)

1. Professional Sports Experience (Hard Surface + Elastic Bottom Structure)

• Hard Surface Layer: Ensures stable ball rebound with a rebound rate ≥ 90%, no ball sinking or sticking, making it ideal for competitive sports such as basketball and tennis.

• Elastic Bottom Layer: Delivers about 63% shock absorption and meets standard vertical deformation requirements, greatly reducing the risk of ankle and knee injuries during sports.

• Moderate Anti-Slip Performance: Friction coefficient ranges from 0.4 to 0.7, enabling safe emergency stops and direction changes, even in wet and humid environments.

2. Durability & Weather Resistance: Long Outdoor Service Life, Sturdy & Wear-Resistant

• Long Service Life: 8-10 years of normal outdoor use, far exceeding the service life of acrylic materials (5-6 years).

• Strong Weather Resistance: UV-resistant, withstands extreme temperatures from -30℃ to 80℃, and resists rain and ozone erosion; no fading, cracking or whitening.

• Wear-Resistant & Stain-Resistant: High surface wear resistance with Taber abrasion ≤ 30mg/1000 revolutions, stains cannot penetrate the surface, and daily cleaning only requires clean water.

II. Environmental Protection & Safety: Meets Strict National Standards in China (Essential for Schools & Public Venues)

• Water-Based & Low VOC: Free of benzene, TDI and heavy metals, fully compliant with national standards including GB 36246 and GB 18583.

• Non-Toxic During Construction & Use: No harmful residues after curing, suitable for densely populated places such as schools, kindergartens and residential communities.

III. Construction & Cost: Ultra-High Cost-Effectiveness (Top Choice for Engineering Projects)

• Low Foundation Requirements: Can be directly constructed on cement bases without rebuilding the foundation, cutting costs significantly for old venue renovation.

• Simple Construction: Available in single-component or two-component formulas, only requires proportional mixing before use; short construction period and moderate requirements for construction teams.

• Optimal Comprehensive Cost: Long service life, low maintenance demand and long renovation cycle, making it more cost-effective than acrylic and traditional PU materials in the long run.
