EPDM rubber granules are the top choice for running tracks, playground safety flooring and outdoor landscape paving, thanks to outstanding elasticity, weather resistance and safety.
Most construction projects always have leftover EPDM granules upon completion. Yet many project managers and workers lack proper storage methods, causing serious quality deterioration, performance loss and huge material waste.
Bad storage easily leads to EPDM fading, hardening, loss of elasticity and caking — making the granules totally useless for later construction and repairs.
As a professional EPDM manufacturer with years of production and export experience, we’ve summed up practical standard storage guidelines. Protect your leftover EPDM quality perfectly and greatly extend its service life.
Optimal Storage Conditions for Unused EPDM Granules
the EPDM granules storage environment must meet these three core conditions, which are the basis of proper EPDM granules storage:1. Constant Temperature & Avoid Extreme Heat/Cold
Store unused EPDM granules in a cool, dry indoor special storage area with a constant temperature controlled between 5°C and 30°C.
It is strictly forbidden to place EPDM rubber granules in direct sunlight, near heaters, fire sources or places with sharp temperature fluctuations.
High temperature environment will accelerate the aging speed of unused EPDM granules, while low temperature will make EPDM granules brittle and easy to break during later construction and use.
2. Dry & Ventilated Storage Space
Humidity is the biggest enemy of EPDM granules storage.
When storing unused EPDM granules, you must choose a well-ventilated, professional moisture-proof warehouse with ambient humidity stably kept below 60%.
A damp storage environment will cause unused EPDM granules to absorb a lot of moisture, grow mold on the surface, or stick together into agglomerates, which will seriously affect the bonding effect and construction quality of EPDM rubber granules during later use.
3. Stay Away from Corrosive Chemicals & Sharp Objects
Store unused EPDM granules separately from oils, acids, alkalis, organic solvents and other corrosive chemicals,
these harmful substances will directly corrode the surface of EPDM granules and permanently damage their physical performance.
At the same time, keep EPDM rubber granules away from sharp objects to prevent the waterproof packaging from being punctured, resulting in a large amount of moisture and dust intrusion into the packaging and damaging unused EPDM granules.
Step-by-Step Proper Storage Method for Leftover Unused EPDM Granules
1. Seal Unused EPDM Granules Tightly ImmediatelyAfter finishing the daily construction work, pour all leftover unused EPDM granules back into the original special waterproof packaging bag at the first time, squeeze out all excess air inside the packaging bag, and seal the bag firmly with a high-viscosity sealing tape or a special sealing clip.
For EPDM granules that need long-term storage, it is recommended to carry out double-layer waterproof sealing treatment to completely isolate external moisture and dust.
Place the fully sealed unused EPDM granules on a raised plastic or wooden pallet, never put EPDM rubber granules directly on the damp ground.
Direct contact with the ground will quickly transfer ground moisture to the packaging, causing unused EPDM granules to become damp and agglomerate, directly scrapping high-quality EPDM granules.
Stack the packaged unused EPDM granules neatly in a classified manner, and do not stack the packaging bags too high to prevent the bottom EPDM rubber granules from being crushed and deformed by heavy pressure.
Do not place any heavy objects on the EPDM granules packaging bags, so as to keep the unused EPDM granules in a loose state and avoid irreversible agglomeration.
4. Label Clearly for Standardized EPDM Granules Management
Stick a clear identification label on each bag of sealed unused EPDM granules, mark the exact storage date, color and specific specifications of EPDM granules, which is convenient for regular inspection and sequential use.
In the process of EPDM granules long-term storage, remember to use the earlier stored unused EPDM granules first to avoid long-term idle storage leading to performance degradation.
Choose High-Quality EPDM Granules for Easier Storage
Our factory specializes in producing high-quality EPDM rubber granules with stable and mature formula, added high-efficiency anti-aging and UV stabilizers, which are more resistant to long-term storage and not easy to deteriorate.
Even if stored for a long time under proper EPDM granules storage conditions, our unused EPDM granules can still maintain excellent physical performance, greatly reducing the loss of leftover materials for your project.
We also provide customized thickened professional packaging for EPDM granules, with super strong waterproof and moisture-proof performance, further simplifying your unused EPDM granules storage work and making material preservation more worry-free.Conclusion
Correct and proper storage of unused EPDM granules is the top priority to maintain EPDM rubber granules performance and avoid material waste.
The core of effective EPDM granules storage lies in strict sealing, comprehensive moisture-proof, constant temperature control and effective sun protection.
Following the above EPDM granules storage methods and key precautions can perfectly preserve the quality of leftover unused EPDM granules, ensuring that these EPDM rubber granules can be used normally in subsequent construction and repair projects.
