What is it?
Daruwin's Polystyrene Beads for Insulation foam holds a different meaning and value to the people in the company than that of the common packaging foam that you may easily find in the market. It is a highly specialized raw material with a specially formulated and structurally designed to work in the cold storage insulation panel systems. When foaming and molding, Polystyrene Beads for Insulation turns into the main material of the cold storage insulation panels which will be in charge of the heat insulation, temperature locking, and stabilizing the overall temperature of the cold storage.
Where can EPS granules be used?
Polystyrene Beads for Insulation's high closed-cell structure has prevented water from entering the material completely, therefore it is a cold storage material perfect fit because cold storage is a place with very high humidity; its low thermal conductivity is the reason why the cold storage can still hold cold even though the equipment is consuming energy; its density is very convenient as that is the reason why one can easily adjust the density in one panel to different thicknesses and grades; and its uniform foaming is the reason why they are stronger and more stable and hence they do not collapse or crimp even after many years of usage.
Why are EPS granules suitable for cold storage insulation panels?
1. High closed-cell structure once Polystyrene Beads for Insulation are foamed, thus the material being less likely to assimilate water. The greatest cold storage enemy is definitely moisture. Once the materials are filled with water, their heat insulation ability will be reduced significantly. Our EPS is with a closed-cell level of more than 90%, hence, "every bubble is tightly sealed" which means that it is almost impossible for moisture to penetrate.
2. Low thermal conductivity of the individually tightly foamed bead of EPS can drastically reduce the energy consumption of cold storages. EPS is a product with very low thermal conductivity. When converted to panels, it becomes a highly efficient insulation layer.
3. Good foaming of the evenly distributed spherical particles of Cavity Wall Insulation bead retains the foaming of the particle structure, thus providing a stable core density.

Daruwin's expanded polystyrene bead is capable of producing a foamed material with a compressive strength ranging from 6 to 8 kg/cm², and also with a bulk density of ≤18 kg/m³, thus the resulting panels are not only light in weight but also have good resistance to compression, hence the panels will not collapse when used for a long time in a low-temperature condition of cold storage. The foaming factor of the expanded polystyrene bead can be between 40 and 70 times, thus, it not only satisfies the requirement for lightness of the material but also ensures that the overall structural strength of the panels is maintained, which is a very important point for cold storage materials.
Packaging and Logistics
We are willing to explore various packaging options to cater to the requirements of our engineering clients, manufacturers of cold storage facilities, and export customers, and at the same time, we make sure operations run smoothly. Our regular packing consists of 25kg woven bags with an inner PE moisture-proof bag for the protection of the product against moisture during shipment. Big orders can also be supplied with 500kg-1000kg ton bags, which are ideal for direct loading to the cold storage panel production line.
Export customers may choose to use pallets and stretch wraps as their method of container loading, sorting, and customs clearance. The Daruwin factory is equipped with weighbridges and a large warehouse for loading, weighing, unloading, and delivering full and less-than-truckloads rapidly and effectively.
FAQs:
1. Will expanded polystyrene bead be affected by moisture?
Daruwin's expanded polystyrene bead has a high closed-cell rate, which makes it less susceptible to water penetration, and it keeps its long-term stability after production.
2. Is it possible to customize the density of expanded polystyrene bead?
Different densities of expanded polystyrene bead are required for various cold storage levels and panel thicknesses, and Daruwin is willing to make the density adjustment perfectly according to your process requirements.
3. Is it possible to use expanded polystyrene bead in extremely low-temperature cold storage?
Sure, expanded polystyrene bead is very resistant to low temperatures and it remains very stable and non-brittle even at temperatures that are tens of degrees below zero.
4. Will the foamed sheets collapse?
The uniformity of the foaming of the expanded polystyrene bead as well as the consistent density result in good stability over a long period making it unlikely to collapse.
R&D Capabilities
The main reason for the uninterrupted supply of raw materials and the easily controlled quality is the location of the Daruwin base near the Fushun Petrochemical Industrial Zone.
The entire project, which covers 185 acres and has an annual capacity of 240,000 tons, is a 350 million yuan investment, and it is one of the largest EPS new material production bases in China.
The factory is equipped with independent tank areas, automated conveyor lines, a large finished product warehouse, a testing center, a weighbridge system, and other supporting facilities, having a mature quality system from foaming performance to density control.
