Product Introduction:
Our Graphite EPS Raw Materials are a variant of the foamed raw materials designed to be used in the manufacturing of hybrid wall panels, prefab wall panels, and lightweight wall panels for energy-efficient buildings. We dope graphite into the Expandable Polystyrene With Graphite (EPS) beads to enhance the insulation properties of the EPS beads and to improve their chemical stability. In this way, the EPS beads not only become more suitable for the composite wall panels that require insulation, lightness, building, pressure resistance, and durability but also multifunctional.
Product Applications:
Daruwin is a reputed EPS bead manufacturer based in Fushun, Liaoning. We are committed to continuously produce high-quality and high-performance EPS products for our customers and at the same time, we will continue to provide reliable services, stable supply, and professional technical support. Our research staff of advanced materials scientists invents Black Graphite EPS granules compositions that can accurately cater to the stringent needs of various sectors such as construction, packaging, manufacturing, and healthcare. Choosing Daruwin as your business partner will mean having a trusted partner for the long term rather than just a quick supplier.
Benefits of the product:
First of all, graphite EPS beads can be instrumental in delivering a more regular and energy-efficient overall performance. Actually, they mostly reflect and absorb the infrared heat, so the wall panel's having lower thermal conductivity and thus being more energy-saving even when the thickness remains unchanged. Besides, graphite EPS beads are evenly foamed so they have better compatibility with cement layers, mortar, metal panels, and other materials, and there is less risk of hollow, cracks, or delamination.

Storage Recommendations:
To ensure the stable performance of the EPS graphite granules, it is recommended to store the product in a dry, ventilated, and dark environment, avoiding prolonged exposure to sunlight or high temperatures to prevent affecting the foaming effect. Do not open the packaging and keep it away from moisture, rain, or ground. Granules storage should preferably be in batches and categories in a warehouse, using a first-in, first-out (FIFO) system, as it prevents granules from gathering caused by long storage. In summer or areas with high humidity, increasing the warehouse ventilation is advised to maintain a neat and dry environment which will be helpful in granules foaming stability during use.
Our Factory:
Daruwin's manufacturing plant is equipped with a large-scale EPS granules production line of 240,000 tons yearly capacity, which is more than sufficient for the composite wall panel manufacturers' large-volume supply needs and guarantees stable delivery even for a highly urgent order. Being located next to Fushun Petrochemical, Daruwin's factory is in a better position to have a more stable raw material supply, cheaper prices, and, on top of all these, a more significant level of control over delivery times. From an R&D perspective, we offer order-based customization services, such as providing customized EPS granule density curves, foaming ratios, flame retardant ratings, and production process guidance for different wall panel molds all adjusted to the client's project requirements. Daruwin products are always strictly manufactured following standards such as GB50016-2014 and GB/T 29906-2013, and supervised by the ISO quality system, thus meeting the requirements of domestic and international engineering clients, who can rely on them without any doubt.
FAQs:
Q: What are the primary differences between wall panels of graphite EPS and normal EPS?
A: The graphite EPS offers a significantly better thermal insulation, higher flatness, enhanced moisture resistance, and more stable performance in general.
Q: Are the wall panels for both the exterior and interior sides of the wall?
A: Of course. The outside walls are primarily a thermal and weather barrier, whereas the inside ones are mainly for light weight and thermal insulation; graphite EPS matches well with both scenarios.
Q: Would it be possible to make Graphite EPS Raw Materials fire-retardant?
A: We can offer different grades based on the project's needs, and this is not an issue.
Q: I don’t have the foaming equipment that is the latest model. Will I still be able to use Graphite EPS Raw Material Fire Proof?
A: Graphite EPS Raw Material Fire Proof is suitable for general EPS foaming equipment, and the process adjustment is quite simple.
Q: Are you able to provide samples and trial molding?
A: Yes, first, we can supply testing sample material.
About Us:
Production capacity of 240,000 tons per annum is the goal of Daruwin factory. Considering the scale of the factory, it is quite logical that it is huge. Tank farm facilities offer huge storage capacity, so the supply of raw materials is always guaranteed; foaming lines are automated and lengthy, granules go through aging and screening along a conveyor; different classes of finished products are neatly arranged in a warehouse, which is perfectly set for a long-term supply. Daruwin has been in the EPS bead processing industry for years, thus gaining a vast amount of experience. Please feel free to reach out to us if you require any product.
