EPDM rubber granules are the core material for high-quality running tracks, playgrounds, and sports surfaces.
However, many buyers unknowingly purchase long-stored EPDM granules (kept in warehouses for years) at low prices, leading to serious quality and safety issues.
As a professional EPDM manufacturer, we strictly adhere to the principle of “production only after order confirmation”—we never sell aged or expired inventory.
In this article, we explain the severe impacts of using long-stored EPDM granules and why fresh production is critical for your project.
5 Major Impacts of Using Long-Stored EPDM Granules
1. Severe Loss of Elasticity & Shock Absorption
EPDM granules rely on their rubber elasticity to provide cushioning and shock absorption. When stored for years (especially in improper conditions), the rubber ages, hardens, and loses elasticity.
• Result: The track becomes rigid, fails to protect athletes’ joints, and increases injury risks.
2. Reduced Tensile Strength & Easy Cracking
Long-term storage causes EPDM granules to become brittle. Their tensile strength and elongation drop sharply, failing to meet industry standards.
• Result: The track cracks, peels, and breaks under heavy use or temperature changes—requiring costly repairs or full replacement within 1–2 years.
3. Fading & Discoloration (Aesthetic & Safety Issues)
Stored EPDM granules lose UV stabilizers over time. Even if they look normal, their color fades rapidly after installation.
• Result: The track turns pale or uneven, losing visual appeal. Faded surfaces also reduce traction, increasing slip risks.
4. Odor & Toxicity Risks
Aged EPDM granules may release harmful volatile organic compounds (VOCs) due to material degradation.
• Result: Strong, unpleasant odors linger for months, and toxic substances pose health risks to students and athletes—especially in closed or poorly ventilated areas.
5. Poor Adhesion & Short Lifespan
Old EPDM granules have reduced bonding ability with adhesives.
• Result: The track surface delaminates, bubbles, or detaches easily. The lifespan is shortened to 3–5 years (vs. 10–15 years for fresh EPDM).
Our Factory: Fresh Production for Every Order—No Stored Inventory
To avoid these risks, our factory operates on a “made-to-order” model:
1. No long-term storage: We produce EPDM granules only after receiving customer orders, ensuring 100% freshness.
2. Strict quality control: Fresh granules meet all elasticity, tensile strength, and safety standards.
3. Customizable production: Tailor particle size, color, and thickness to your project needs.
4. Fast delivery: Efficient production lines ensure on-time delivery without inventory delays.
Why Choose Fresh EPDM Granules from Our Factory?
• Guaranteed performance: Fresh EPDM maintains elasticity, durability, and color for 10–15 years.
• Safe & eco-friendly: Non-toxic, odorless, and compliant with REACH/RoHS standards.
• Cost-effective: Avoids frequent repairs and replacements, saving long-term costs.
• Factory direct: Competitive prices with no middlemen or hidden inventory risks.
Conclusion
Using long-stored EPDM granules for running tracks leads to poor performance, safety hazards, and high maintenance costs. Our factory's fresh, made-to-order EPDM granules ensure your track is safe, durable, and long-lasting.
