What is Plastic EPS Raw Material Beads?
Daruwin Plastic EPS Raw Material Beads is a special kind of EPS granules specially designed and developed for the manufacturing of structural insulation boards. It is not a foam product for a foaming process. The material with its density, formula, foaming stability, closed-cell structure is specially adjusted to satisfy the dual function of a structural board - both as a load carrier and as insulation. Daruwin's Plastic EPS Raw Material Beads perfectly fitted these requirements. Plastic EPS Raw Material Beads are characterized by an extremely high rate of closed cells very evenly foamed and a super dense internal structure. When structural insulation boards are based on this, the result will be higher core stability and thus, superior resistance to deformation. The phenomena of collapse, bending, and hollowing after a long period of use will thus be avoided. It is the ideal material for the manufacture of structural insulation boards.
Where can Plastic EPS Raw Material Beads be used?
To be honest, Plastic EPS Raw Material Beads may be visually just a few tiny particles, but they are revolutionizing the field of structural panels for insulation. It can be used in almost any construction system where two conditions are required, namely a) structural load bearing and b) thermal insulation. Take the case of prefabricated buildings for example, Non Flammable EPS Expandable Polystyrene Bead is used as a core material of structural panels, thus the overall weight of the panel is reduced while still providing stable insulation performance, which means that panel installation becomes easier and the whole structure more durable. Coupled with integrated exterior wall insulation and structural systems, it works as the principal insulating layer in the composite panel, thereby significantly reducing heat transfer and, at the same time, improving energy efficiency.
Why is Plastic EPS Raw Material Beads suitable for structural insulation boards?
1. Because of a very stable foaming structure, the boards do not get hollowed, do not collapse, or do not get twisted.
Uneven boning inside is the main reason why structural insulation boards become hollow, the core strength becomes unstable. Daruwin's Expandable Polystyrene EPS Granules are the right choice for load-bearing applications, they have a uniform spherical shape, a very stable foaming coefficient, and a dense, easy-to-control internal structure.
2. Extremely high closed-cell rate and the water absorption is fully negligible.
Plastic EPS Raw Material Beads is a material with a closed-cell rate of ≥90% and a water absorption rate of ≤2%. The durability of a structural board is largely determined by whether or not it is water absorbent.
3. Density can be varied for different types of boards to satisfy the different needs of the boards.
What if you want materials lighter? What if you want stronger load-bearing capacity? What if you want stronger insulation? The density and the size of a Plastic EPS Raw Material Beads piece can be changed according to the needs of the project.
The Key Concerns for Structural Insulation Board Manufacturers:
For those producing structural insulation boards, three main issues have been the biggest concern for the manufacturers: the uniformity of the foam core, the structural stability, and the resistance of the product to changing shapes after long usage. Our Expandable Polystyrene EPS Granules essentially solve these three biggest problems as the particles are almost perfect spheres, the density can be easily and accurately controlled, and the foam core is less hollow, or has less weak spots; also, the closed-cell rate can already be more than 90%, the material practically does not absorb water, and is also very resistant to moisture, so after many years of use EPS boards installed in walls will not lose their shape. The proposition of Expandable Polystyrene EPS Granules comprises that it is production-line-favorable; almost all the structural board-making technology that are presently available can be directly used without any major re-equipment.
Our Factory's Strength:
Daruwin is one of the largest EPS raw material production base with 185 acres of the land and an annual output capacity of 240.000 tons that the company can operate continuously. Together with the Fushun Petrochemical, the base is located in the neighbouring area and therefore the supply of raw materials is very stable and transportation costs are low. R&D-driven development is one of our major policies that we always maintain, thus we explore different formulations for various downstream applications (such as structural panels, panels for cold stores, safety components, and decorative panels), in this way each agent can achieve its performance advantages in the respective fields.
Packaging and Logistics:
We have always been flexible in our packaging and logistics to meet the requirements of structural insulation board manufacturers. Typically, the products are packed in 25 kg woven bags with a PE liner that protect from moisture and provide easy handling. Besides pallets, stretch film, custom shipping markings, and even export-grade wooden pallets, we can also pack 500-1000 kg ton bags for large orders or export needs to meet export standards. We are located close to Shenyang and Fushun, so we have a lot of logistics channels through which both full truckload and less-than-truckload (LTL) shipments can be conveniently and quickly loaded. Therefore, whether domestic projects or sea freight exports, we can guarantee both the efficiency and the reliability of the operations.
FAQs:
Q: Does the structural insulation board strength mainly depend on EPS (Expanded Polystyrene)?
A: The most important one is Transformable Polystyrene EPS Granules; it is the element that sets the weight, the thermal insulation capacity, and the resistance to deformation of the board.
Q:Could the material be flame-retardant
A: These materials can be used together with the flame-retardant systems, and the boards thus made can fulfill the specified standards.
Q: Is the foaming process hard to be regulated?
A: The particles are perfectly round and stable, and the density range is easy to handle, so that foaming becomes less complicated.
Q: Would it be possible for the boards to collapse over a large area?
A: High structural stability and excellent long-term load performance.
