Product Introduction:
Daruwin's graphite EPS granules are an innovative foaming material that is carefully engineered to upgrade underfloor heating insulation boards. In contrast to regular EPS, EPS Graphite for Insulation Board contains more than 50% of fine graphite in the granules, which more effectively reflects and absorbs infrared heat, resulting in stronger insulation, lower heat losses, faster underfloor heating, and higher energy savings.
Product Applications:
Daruwin's graphite EPS granules are mainly used in underfloor heating insulation boards. Besides, they can be used in the production of underfloor modular boards, backfill insulation layers, heating pipes insulation, and even hot water circulation systems and floor insulation in energy-efficient buildings. The graphite technology in EPS Graphite for Insulation Board is the key to faster surface heating and more extensive energy-efficient indoor space.

Graphite Technology:
Graphite is a material that both reflects and absorbs infrared heat radiation. By incorporating graphite, the granules reflect significantly more heat and lose considerably less heat, thus achieving a thermal conductivity of 0.033 W/(m·K). Graphite EPS features a density of 15–30 g/L and is considered very light by most standards. Workers can move, place, and cut materials on the construction site more efficiently. The Daruwin factory is capable of supplying B1, B2, and other different flame retardant grades of EPS Graphite Polystyrene Raw Material to meet the safety requirements of indoor underfloor heating, public building projects, and overseas certifications (especially in Europe and the Middle East). There are strict requirements for flame retardancy in overseas projects, and graphite EPS finds it easier to pass the certification.
Daruwin Factory Advantages:
Powered by a 240,000-ton annual production capacity, Daruwin's factory serves as a new material base with a very strong supply capacity. Even during the underfloor heating peak season, which is also a period of a surge in orders, we can efficiently handle the demand, thus ensuring that there are no delays and project disruptions. Our raw material supply is plentiful and dependable, our prices are more competitive, and our logistics and transportation are more convenient. Our R&D team can formulate customized graphite EPS with the objective of underfloor heating in mind. Density, foaming ratio, and flame retardant rating can all be changed to suit the requirements of the project. We can also assist you with production process guidance if you provide us with information regarding your equipment and molds so that your factory will have more stable material performance. All EPS Graphite Polystyrene Raw Material-grade materials meet national standards such as GB50016-2014 and GB/T 29906-2013 and have been awarded ISO quality system certification. For foreign clients, this quality and system facilitateloal building energy efficiency audits, and project progress is smoother.

FAQ:
Q1: What is the biggest difference between graphite EPS and ordinary EPS?
Strong insulation, higher heat resistance, and better stability of the performance of the underfloor heating systems.
Q2: Is it possible to use ordinary EPS for underfloor heating panels?
Yes, but the performance of graphite EPS is better and the system is more energy-efficient.
Q3: Is it compatible with my foaming production line?
They are totally compatible; normal EPS foaming equipment can be used for production.
Q4: Would you be able to provide models with flame-retardant properties?
Indeed, we can provide various flame-retardant grades depending on the requirements of the project.
Q5: Can I do a small-batch trial foaming first?
Yes, we support small-batch sampling and slab testing.
