Product Introduction:
Daruwin's EPS granules are a lightweight foamed raw material made especially for the production of thermal insulation pads. The foam formed thereby has low density, excellent thermal insulation properties, low water absorption, and will have stable compressive strength, thus it is suitable for thermal insulation pads in food delivery, household pot holders, coasters, and various other small pad products that require "heat insulation, anti-scalding, and heat preservation." In other words, it is a lightweight, durable, and cost-effective material whose thermal insulation performance is stable. When using it for thermal insulation pads, the molding efficiency is high and the end products are more visually attractive and more durable.
Why is Graphite granules EPS thermal insulation suitable for thermal insulation pads?
The addition of high-purity, high-reflectivity graphite particles is the main reason for Daruwin's Graphite granules EPS thermal insulation is better at insulating heat than ordinary white EPS. These graphite particles absorb, reflect, and weaken infrared thermal radiation, effectively insulating heat. As a result, we can achieve a thermal conductivity level of 0.033 W/(m·K), which is less than that of basic EPS and gives excellent thermal insulation.
| Density (Bulk Density) | 15–30 g/L |
| Thermal Conductivity | 0.033 W/(m·K) |
| Compressive Strength | 0.5–0.6 MPa (typical value) |
| Flexural Strength | Approximately 0.15–0.2 MPa depending on the model |
| Closed-cell content | ≥90% |
| Applicable foaming ratio | 40–70 times |
Product Features:
1. The granules are made of graphite which has the property of absorbing and reflecting the infrared heat and hence provides better temperature insulation.
2. After foaming, thermal insulation made of graphite granules EPS results in a uniform closed-cell structure, the structure is stronger due to the new formation of the thermal insulation pad.
3. Minimal water absorption; it resists getting wet. EPS in fact has a closed-cell structure and hardly takes up any moisture. It won't swell, distort, or become moldy even the floor heating environment is humid.
4. The granules have the feature of producing a very high amount of foam which is stable in size and this is the reason the resulting foam pads are the ones of excellent flatness and the production process becomes simpler.

The EPS graphite particles are capable of absorbing and reflecting infrared heat, thereby greatly enhancing the insulation performance of the insulated panels. Moreover, this feature enables the panels to comply with higher energy efficiency standards even with the same thickness. Consequently, it is very suitable for underfloor heating systems that are frequently used in foreign markets. Its lightness and durability not only help to avoid damage during transportation but also make it a good choice for long-distance sea shipment. Besides that, the closed-cell structure prevents it from absorbing water and moisture, so that it won't be deformed even after repeated freezing and thawing in cold countries. For foreign projects, installing graphite EPS insulation panels helps the clients to pass local building energy efficiency certification and at the same time, it lowers heat energy consumption, which is the reason why export projects usually prefer graphite EPS materials.
Factory Capabilities:
The Daruwin factory is capable of delivery and manufacturing on a large scale. An annual production capacity of 240,000 tons allows it to accommodate even large-sized export orders and the delivery of engineering projects in concentrated batches, which is particularly advantageous when the deadlines are tight. An order-driven R&D model is employed by the factory, and it is fitted with brand-new equipment that is specially designed for EPS and new energy-saving materials, thus production is stable and quality control is made easier. Its proximity to Fushun Petrochemical guarantees the local availability of raw materials at the best price level, and the lead times are not dependent on upstream suppliers, which is especially crucial for international customers.
About Us:
The Daruwin base is fully equipped with a large tank farm that is isolated from other installations, so it can unload full EPS Graphite Resin Beads Raw Materials directly into the system on arrival, thus it avoids environmental pollution or raw material fluctuation. The automatic conveyor belt links the foaming and screening areas, so manual material handling is not necessary and particle damage is minimized. Finished products are neatly stacked and quick dispatch capabilities are among the highlights of the warehouse system. The weighbridge captures data for every outgoing shipment in a very clear manner, thus providing large-volume customers with a rationale for security.
