EPDM Playground Surface Structure and Benefits

1. General Structure of EPDM Playground Surface
An EPDM rubber playground typically consists of three main layers:
- Layer 1: EPDM Wear Layer with PU Binder
The top layer consists of EPDM (Ethylene Propylene Diene Monomer) granules mixed with PU binder, with a thickness of 8-10mm. This layer is responsible for the surface color and patterns, while also offering wear resistance and weather durability.
- Layer 2: SBR Rubber Cushion Layer with PU Binder
This layer is composed of SBR (Styrene Butadiene Rubber) granules mixed with PU binder, with a thickness ranging from 10-20mm. It provides elasticity and shock absorption, ensuring child safety.

- Layer 3: Adhesive Primer
A PU primer is applied evenly to the base surface (concrete or asphalt) using a roller, enhancing adhesion between the foundation and the rubber layers.

2. Detailed Composition of Each Layer
- Adhesive Primer Layer:

• Uses PU Primer, applied as a thin and even layer over the base surface to create a strong bond between the foundation and rubber layers.

- SBR Rubber Cushion Layer with PU Binder:

• Material: SBR rubber granules (1-4mm in size).
• Mixing Ratio: Approximately 12-14% PU binder relative to the rubber granules.
• Application: The SBR granules are mixed with PU binder and then spread and leveled evenly over the primed base.

- EPDM Wear Layer with PU Binder:

• Material: EPDM rubber granules (1-4mm in size), available in various colors.
• Mixing Ratio: Approximately 16-20% PU binder relative to the rubber granules.
• Application: The EPDM granules are mixed with PU binder and then spread and leveled over the pre-installed SBR cushion layer.

3. Overall Thickness
The total thickness of an EPDM playground surface typically ranges from 20mm to 50mm, depending on specific safety and design requirements. The thickness is determined based on the height of playground equipment and safety standards to ensure effective shock absorption.
4. Safety Standards
The design and construction of EPDM rubber playground surfaces must comply with international safety standards such as EN 1177:2018 or ASTM F1292, ensuring optimal impact absorption and child protection.
Proper selection and installation of EPDM playground layers not only guarantee child safety but also enhance the durability and aesthetic appeal of the playground.

5. Key Benefits of EPDM Playground Flooring
- Safety & Injury Prevention

• Shock Absorption: Reduces impact from falls, minimizing injuries such as fractures or sprains.
• Non-Slip Surface: Provides excellent grip, preventing slips and falls, even in wet conditions.

- Durability & Weather Resistance

• High Wear Resistance: Withstands heavy foot traffic and impact without deteriorating.
• UV and Heat Resistant: Maintains color vibrancy and performance in outdoor conditions.

- Aesthetic & Customization Options

• Variety of Colors & Designs: Available in over 62 colors for creative playground designs.
• Customizable Shapes & Patterns: Can be tailored to any design requirement.

- Eco-Friendly & Health-Safe

• Non-Toxic Materials: Free from harmful chemicals, ensuring child safety.
• Environmentally Friendly: Uses recycled rubber, contributing to sustainability.

- Easy Maintenance & Cleaning

• Low Maintenance: Excellent water drainage, easy to clean, and cost-effective upkeep.
• Self-Cleaning Properties: Resistant to dirt and stains, maintaining its appearance.

Conclusion
EPDM playground surfaces provide a perfect combination of safety, durability, and visual appeal. With a multi-layered structure that ensures excellent shock absorption, weather resistance, and customization options, these surfaces meet international safety standards and are ideal for children’s play areas. Choosing high-quality EPDM flooring guarantees long-lasting performance, reducing maintenance costs while enhancing the overall play experience.
