EPDM Coloured Rubber Granules
Tianyou's EPDM Coloured Rubber Granules are engineered for high‑safety sports and play surfaces. With rubber content options from 10% to 17%, you can match durability and elasticity to your specific application – from kindergarten playgrounds to professional basketball courts. UV‑stable pigments ensure through‑body colour that won't fade or chalk, even under intense sunlight. Available in multiple particle sizes (0.5–3 mm) to suit different finish textures. When paired with our high‑strength, clear‑curing binder, the system delivers excellent adhesion, vibrant colour, slip resistance, and superior drainage – making it the ideal choice for running tracks, play areas, fitness trails, and parks.

EPDM Coloured Rubber Granules
Precision‑Engineered for Durable, Safe & Vibrant Surfaces
Choose the right rubber content, particle size, and binder to create a surface that performs, protects, and remains beautiful for years – from playgrounds to professional sports courts.
Understanding EPDM Granules – The Material Science
EPDM (Ethylene‑Propylene‑Diene Monomer) is a high‑performance synthetic elastomer known for its excellent chemical stability, outstanding wear resistance, elasticity, oil resistance, anti‑aging properties, and UV protection. When processed into coloured granules, EPDM becomes the ideal surfacing material for applications that demand safety, durability, and visual appeal.
The performance of an EPDM granule system is determined by four critical factors: the rubber content of the granules, the quality of the colour pigments, the particle size (mesh) selection, and the binder (adhesive) used. Making the right choices in each area ensures a surface that is cost‑effective, long‑lasting, and visually stunning – with no premature fading, particle loss, or structural failure.
✔ Key Features
- 🧪 Rubber content 10–17% – match performance to use
- 🎨 Through‑body colour – UV‑stable, no fading
- 📏 Multiple particle sizes – 0.5–3 mm
- 🔗 High‑strength binder – for adhesion & clarity
- 💧 Excellent drainage – no standing water
- 🛡️ Slip‑resistant & shock‑absorbing
Four Critical Factors for a Perfect EPDM Surface
1. Rubber Content – The Heart of Performance
The proportion of EPDM polymer in the granule determines its elasticity, abrasion resistance, and durability. Higher rubber content delivers better resilience and longer life – but also increases cost. Choose according to the impact intensity of your venue.
| Rubber Content | Recommended Application | Performance Benefit |
|---|---|---|
| 10% | Kindergarten playgrounds, basic track top layers | Cost‑effective for light‑duty use |
| 13% | Hybrid running track surface layers | Balanced resilience and wear resistance |
| 17% | Basketball, tennis, high‑impact sports courts | Maximum elasticity, impact absorption, and longevity |
Principle: Use the highest content necessary for your application – never compromise performance, but avoid overspecifying and wasting budget.
2. Colour Stability – Pigmented Through, Not Just Coated
- ✓ High‑quality dyes – pigments are mixed into the EPDM compound before curing, not applied after granulation.
- ✓ Through‑body colour – even after surface wear or abrasion, the colour remains consistent – no white or faded spots.
- ✓ UV‑stabilised pigments – resist degradation from sunlight, ozone, and acid rain – ensuring long‑term vibrancy.
- ✓ Avoid coated granules – cheap products only colour the surface; wear exposes the dull base material.
3. Particle Size (Mesh) – Texture and Coverage
EPDM granules are manufactured in sheets and then crushed to specific particle sizes. While the production cost is the same regardless of size, the final surface texture and visual effect differ significantly.
- • 0.5–1.5 mm – fine texture, smooth finish, used for some spray‑on track surfaces.
- • 1–2 mm – popular for kindergarten playgrounds and running track top layers – good balance of texture and cushioning.
- • 1–3 mm – coarser texture, preferred for some court surfaces; offers higher slip resistance.
- • Choice – there is no universal "best" size; it depends on the installer's technique and the client's aesthetic preference.
4. Binder (Adhesive) – The Glue That Determines Longevity
The binder binds the EPDM granules together and to the substrate. Even the best granules will fail if the binder is poor.
- ✓ Strength – a high‑quality binder ensures granules stay firmly anchored – no particle loss or delamination.
- ✓ Flexibility – after curing, the binder should be tough but not brittle. Brittle binders crack under impact, causing surface wear.
- ✓ Clarity – premium binders cure transparent, allowing the vibrant granule colours to shine through. Poor binders turn yellowish or dark, dulling the final appearance.
- ✓ Application – use a single‑component eco‑friendly PU binder, mixed on‑site as per instructions for consistent results.
System Structure & Performance Benefits
🧱 Layer Structure
- • Single or double layer – depending on application.
- • Top layer – EPDM granules mixed with single‑component eco‑PU binder, trowelled or sprayed.
- • Base (optional) – rubber cushion layer for added shock absorption.
- • Substrate – asphalt or concrete, properly prepared.
🏅 Key Performance Advantages
- 🛡️ Elastic & shock‑absorbing – protects joints.
- 👟 High slip resistance – excellent friction coefficient.
- ☀️ UV & aging resistant – no fading or chalking.
- 💧 Excellent water permeability – no puddling.
- 🎨 Vibrant, customisable colours – patterns available.
- 🔧 Simple substrate requirements – bonds well even to less‑than‑perfect bases.
- 🧹 Low blistering – good vapour breathability.
