Polytrack G+ Unblocked -

| Component | Typical proportion (by weight) | Function | |-----------|------------------------------|----------| | | 45–55 % | Provides skeletal structure, load‑bearing capacity | | Rubber granules (recycled tire crumb) | 15–20 % | Energy‑absorbing matrix, contributes to shock absorption | | Synthetic fibers (polypropylene/ polyester) | 5–10 % | Stabilises the aggregate, reduces migration | | Polymer binder (high‑density epoxy‑based) | 8–12 % | Bonds all particles into a durable, waterproof matrix | | Silica fume / micro‑silica | 2–4 % | Increases density and reduces porosity | | Additives (UV‑stabiliser, anti‑fungal agents) | ≤1 % | Extends lifespan, prevents biological growth |

| Property | Typical Value | Testing Standard | |----------|---------------|------------------| | | 25‑30 | ASTM D2240 | | Dynamic load modulus | 1.6–2.1 GPa | AASHTO T307 | | Coefficient of restitution | 0.55‑0.62 (horse hoof impact) | ISO 10891 | | Water permeability | 2.5 × 10⁻⁴ m s⁻¹ | EN 12568 | | Temperature stability | 0 °C – 40 °C (no loss of elasticity) | ASTM D395 | | Wear rate (kg m⁻² yr⁻¹) | ≤ 0.3 (after 5 yr) | In‑house accelerated wear test | polytrack g+ unblocked
