Product Introduction:
EPS Geofoam Blocks for Construction by Daruwin is an environmentally-friendly product made from an EPS granule specially designed for structural modules with added flame-retardant properties. This product looks like regular white pellets; however, the inside of the pellet has been specially designed for modular systems. The innovation is based on the fact it has a high closed-cell ratio, low water absorption, and a very stable foaming structure, which makes the modules less likely to swell and break even after being taken out of the mold. Moreover, EPS Beads Resin Raw Material complies with flame-retardant standards like B1/B2, which ensures that the flame-retardant performance is stable and that safety is preserved during the construction phase as well as in the long run. The product, EPS Geofoam Blocks for Construction from Daruwin, is a building module that is specifically designed to be used as a flame-retardant one.
Product Applications:
Though it is made up of small EPS granules only, the production lines are capable of transforming these granules into different types of flame-retardant building modules. For the manufacture of common flame-retardant building modules, EPS Geofoam Blocks for Construction plays the role of the lightweight insulation core of the module, which in this way is still able to offer good thermal insulation, yet has enough structural strength. Besides, EPS Geofoam Blocks for Construction is also suitable for use as a non-removable insulation formwork, in which case it brings together the features of lightness, stability, low water absorption, and flame-retardant characteristics, thereby allowing for easier outer shell molding and safer installation. Prefabricated exterior wall modules is one area where it serves as an effective tool for weight reduction of the total wall, thereby offering easy and quick construction, and large area assembly and lifting are especially suitable for it now.
Product Advantages:
Closed-cell ratio ≥90%, almost non-absorbent, and is not affected by dampness or deformation in humid environments.
Flame retardant performance can be regulated, thus stable accomplishment of B1/B2 and other flame retardant levels can be achieved depending on the clients' requirements.
Foaming ratio can be from 40 to 70 times with the result that the modules would be lighter and insulation capabilities stronger.
Good and even distribution of the foam material and tight structural texture; no hollows or crumbles are found in the molding process.
The density is also customizable, thus the users will be able to flexibly change it if different structural strength needs arise.
Flame Retardant EPS Certification Requirements in Different Countries:
Various countries have different standards for fire retardant grades. Consequently, if you are producing modules, panels, and formwork systems, it is very important to adhere to the regulations of the market you are targeting to save yourself a huge deal of trouble.
European Union - Regarded as typical building EPS, it is verbose that one has to comply with EN 13501-1 combustion classification where the most commom requirements are grades E and D. Thus, the grade required of an external wall or structural insulation system might be even B or above. Simply put, besides being flame retardant, EPS Beads Resin Raw Material also need to go through tests related to smoke density and burning droplets.
The American system characterizes mostly heavily on use-case scenarios with each of the states having its own set of fire safety regulations. Nevertheless, EPS for house heating is commonly linked with ASTM E84 (flame spread/smoke generation rating), typically Class A or Class B as requirements. In the US, ICF modules have gained immense popularity, so they are very particular about such things as drips after combustion and the stability of the flame retardant.
Canada is almost identical to the US standard as it also refers to ASTM E84 but has extra requirements for ICF module products besides a few provinces mandating CAN/ULC-S102 testing as well.
Countries in the Southeast Asian region have quite lenient criteria for the fire retardant feature. In most cases, projects stipulate ASTM E84 or BS 476 as standards, however, large commercial buildings and the government projects would set stricter requirements.
Our Factory Capabilities
Daruwin is a state-of-the-art production base that spans 185 acres with an annual production capacity of 240,000 tons that is enough to ensure a very sufficient supply. Raw materials are sourced from the Fushun petrochemical area, ensuring a stable supply, controllable costs, and quick delivery, thus, avoiding the issues of large fluctuations and inconsistent batches. The Daruwin plant is fully equipped with a self-contained tank farm, automated conveyor lines, finished product warehouse, and weighing system, thus, making the whole process very efficient, especially for long-term, large-volume production of building modules. We have a full-fledged R&D and design team and can performance aspects like flame retardancy, foaming ratio, density, closed-cell structure, etc. be customized as per the mold, process, and panel design of the module factory.
Packaging, Stacking, and Transportation Suggestions
We recommend the normal combination of 25kg woven bags with a PE moisture-proof inner lining for use. This kind of packaging is pressure-resistant as well as moisture-proof, and even if the bags are stacked to a great height, it is less likely for them to bulge. If the orders are large, or if the customers are willing to use ton bags, we can provide 500-1000kg bulk bags along with pallets, stretch wrap, and reinforcing straps.
Most Frequently Asked Questions from Import Customers
1. Are your EPS raw materials capable of meeting the flame retardancy requirements of our country? We are open to support the adjustment of the flame retardant system per project requirements and can switch to various testing standards such as EN, ASTM. Third-party testing reports or sample tests may be provided before export.
2. How is the export packaging? Are you able to produce pallets or labels to our specifications?
Both standard 25kg woven bags (with PE liner) and 500-1000kg bulk bags can be produced. Pallets, stretch film, wooden pallets, labels, barcodes, and color coding can all be customized according to your export standards.
3. What is the normal delivery time? Is it possible to supply large orders continuously?
The standard models are ready for shipment within 15-20 days; the carrying out of large export orders will be scheduled according to quantity.
Annual production capacity is 240,000 tons, thus there is more than enough supply. Long-term project stable supply agreement can be made.
4. If I require EPS Expandable Polystyrene Beads with different densities or particle sizes, are you able to make that?
Of course. Density, particle size, and the flame retardant system are elements that can be altered depending on the production line and mold parameters that you give the factory.
About Us:
Daruwin's factory base is the result of a total investment of 350 million yuan, has a huge raw material storage capacity, and is located near the ethylene production core of Fushun Petrochemical, thus, ensuring a stable supply of raw materials. On the production line, foaming, screening, and conveying are all automated, thus, the product stability is easily controlled. The finished product warehouse has implemented a barcode system, thus, shipping and inventory management are transparent and time-saving.
