TPV Playground Materials

Technical Specifications

Key Features & Benefits

• Specific gravity of 1.55 g/cm³ (±0.05) delivers consistent particle mass distribution across wet-pour layers, reducing voidage and settlement in installed playground surfaces.
• Shore A hardness rated at 65°A (±5) provides a verified elasticity baseline that balances surface firmness with the compliance required for fall attenuation in public play environments.
• Tensile strength exceeding 3.0 MPa resists surface tearing and particle fragmentation under sustained foot traffic and dynamic impact loading on sport court and playground installations.
• Elongation at break greater than 400% enables the granule matrix to absorb kinetic energy from falls and impacts without brittle fracture, directly supporting drop-height safety performance requirements.
• UV resistance is confirmed across all standard pigment lines (red, black, white, yellow), preventing color degradation and surface chalking in permanently outdoor-exposed installations.
• Pre-engineered polyurethane binder compatibility ensures complete cross-linked curing integration, eliminating loose particle shedding and maintaining surface structural integrity over the installation service life.

Applications

• Wet-pour public playground safety surfaces use the 1–3mm particle fraction mixed with polyurethane binder to form a seamless, shock-attenuating layer meeting EN 1176 critical fall height parameters.
• Municipal sport court projects specify the 1–4mm fraction for high-wear traffic zones where tensile strength >3.0 MPa and elongation >400% are required to sustain surface cohesion under repeated lateral loading.
• Synthetic sports turf infill installations integrate the 0.5–2mm fraction as a resilient sub-infill layer, providing kinetic energy return and drainage passage beneath artificial grass fiber systems.
• Outdoor safety walkway borders in educational and recreational facilities use custom-pigmented TPV granules to define zoning while maintaining the Shore A 65°A compliance profile across pedestrian impact areas.
• Shock-attenuation zones beneath fixed play equipment structures in school fields use the 1–3mm or 1–4mm fraction in bonded rubber tile or poured-in-place configurations to meet ASTM F1487 impact attenuation targets.

FAQ

Q1: How should the correct particle size fraction be selected for a given installation type?

The 0.5–2mm fraction suits infill and fine-layer applications; the 1–3mm fraction is the standard for wet-pour playground surfaces; the 1–4mm fraction is used where drainage flow rate and surface texture tolerance allow coarser distribution. Final selection should be confirmed against the binder system's specified aggregate range and the installation depth design.

Q2: How do the Shore A 65°A hardness and >400% elongation at break values support drop impact safety compliance?

Shore A 65°A hardness positions the compound in the compliant elastomer range, allowing surface deformation under impact without rebound rigidity; elongation at break exceeding 400% ensures the particle matrix stretches and recovers rather than fracturing under sudden loading. Together these properties underpin critical fall height performance in bonded rubber surface systems.

Q3: What are the structural requirements for polyurethane binder integration with these granules?

TPV Playground Materials granules are formulated for direct compatibility with standard single- and two-component polyurethane binders used in wet-pour surfacing systems. Binder-to-aggregate ratio, ambient temperature, and substrate preparation should follow the binder manufacturer's installation specification to ensure complete cross-linked cure and surface bond integrity.

Q4: Does UV resistance apply uniformly across all available colors, including red, black, white, and yellow?

UV resistance is confirmed across all four standard production colors (red, black, white, yellow), preventing pigment fading, surface chalking, and color migration under continuous outdoor exposure. Custom bespoke pigment orders should include UV resistance verification against the specific colorant batch prior to large-scale procurement.
