Product Introduction:
Daruwin's P-series EPS beads for Electronic Product Packaging are engineered to respond to the highest demands of shock resistance, cushioning, and moldability. These specially treated EPS granules have the capability of being expanded to four times, which results in the EPS beads being full and elastic. It cleverly combines a lightweight structure with efficient absorption of the shocks and vibrations it receives during transportation, thus, it can be used as a perfect protective packaging for various precision electronic devices, home appliances, and digital products.
Where is EPS beads for Electronic Product Packaging used?
Inner trays for various electronic product packaging
Shock-absorbing cushioning blocks and positioning structures
Cushioning pads for electronic equipment transportation
Inner liners for lightweight electronic packaging boxes
Packaging boards for weight-sensitive electronic products
Why are these EPS particles more suitable for electronic product packaging?
Daruwin's Lightweight Packaging EPS beads can be expansion repeated 4 times thus resulting in round and full foam beads that are less prone to collapse. During the foaming process, the material is dry, loose, and does not clump showing good flowability. After molding, the product has a smooth surface, good sealing and complete edges, avoiding common material defects in electronic packaging. In the molded Lightweight Packaging EPS beads, the enhanced resilience property is the most visible change thus impact forces are absorbed effectively resulting in fewer vibrations and drops, hence, the electronic product is safe, no direct impact is transferred to it. It is most important for the protection of displays, electronic control components, and small home appliances.
Model display and recommendations
| Model | Particle size (mm) | Foaming ratio (times) | Typical Application Scenarios: |
| P-103 | 1.2–1.6 | 70–90 | Ultra-lightweight electronic product packaging, lightweight panels, precision electronic cushioning components |
| P-104 | 0.8–1.2 | 65–85 | Conventional electronic product packaging liners, balancing cushioning and strength requirements |
| P-105 | 0.6–0.9 | 55–70 | Electronic packaging requiring higher structural stability |
| P-106 | 0.4–0.7 | 40–60 | Small-sized, highly conforming precision electronic trays |
Why is this material ideal for electronic product packaging?
Lightweight EPS beads for Packaging are compatible with a number of popular pre-foaming machines and forming devices, thus, they have excellent compatibility with both new and old equipment. The pre-foaming is less susceptible to clumping, and the curing time is relatively short, generally within 4–12 hours, faster in summer and slightly longer in winter. When molding, the heating time is short, and the molding window is wide, so there is no need to do repeated mold trials and parameter adjustments. This contributes to a very low rate of production fluctuations and defect rates of factories that require long-term, stable mass production of electronic packaging components.
Practical storage and usage recommendations:
Helpful storage and usage tips: Store EPS granules in a well-ventilated environment not hotter than 25℃. Use the raw materials on a first-in, first-out basis to preserve freshness. When carrying out multiple foaming operations, take care of the foaming interval to prevent excessive shrinkage. Make sure fire safety and anti-static measures are in place in the storage and processing area.
FAQs:
1. Is this EPS suitable for ultra-light electronic packaging?
Yes, especially P-103 and P-104, which can keep cushioning performance at low densities.
2. Will Lightweight EPS beads for Packaging be too soft and not provide enough protection?
No, the product is designed to absorb the impact energy through its cushioning and energy-absorbing properties and not to resist the impact by its hardness. So, the product is very suitable for electronic devices.
3. Is it suitable for automated molding production lines?
Yes, the foam granules have good fluidity and are compatible with automated equipment.
4. Can you provide long-term stable supply?
Yes, we are strategically located near a petrochemical base, supporting long-term cooperation and continuous delivery.
