Product Introduction:
Cold storage wall insulation panels are the primary application of our Black Graphite EPS beads, an advanced raw material. When graphite is added to standard EPS, the resulting material not only has enhanced thermal insulation capabilities but also leads to greater temperature stability of the cooling. Thus, the cold air is well retained inside the room, energy consumption of the refrigeration equipment is significantly reduced. In addition, the cold storage wall panels fabricated with Black Graphite EPS beads are resistant to moisture, stable, and will not crumble even under harsh environments of freezing and high humidity.
Product Applications:
Our Black Graphite EPS beads are generally used in the manufacture of wall, ceiling, and floor insulation panels of cold storages of various nature. Since the material acts as an excellent cold air barrier thus highly resistant to moisture and freezing conditions, it is resorted to extensively in the cold storage of seafood, aquatic products, and fruits and vegetables. It is also a fine bedfellow of low-temperature rooms of food processing plants, cold chain transport containers, and insulated packaging – basically, any application that is challenged with low temperatures and demands high energy efficiency. Simply put, if you aim at temperature controlling, prevention of cold air leakages, and reduction of the power consumption of refrigeration equipment, this is your answer.
What are the differences compared to regular EPS particles?
| Graphite EPS particles | Standard EPS granules |
| Thermal conductivity | Lower thermal conductivity, achievable down to approximately 0.033 W/(m·K) | Regular grade, suitable for general building insulation |
| Low-temperature performance | Stronger resistance to low temperatures, no embrittlement or cracking | Excellent performance in normal temperature environments |
| Radiation reflection capability | Graphite particles absorb and reflect infrared radiation, reducing heat loss | Ordinary infrared blocking effect |
| Water absorption rate | More stable closed-cell structure, less susceptible to water absorption in damp and cold environments | Standard closed-cell structure, suitable for general insulation |
FAQ:
Q1: What are the key differences between graphite EPS and standard EPS?
Graphite EPS has significantly better thermal insulation performance, less absorbent to water, and more resistant to frost, thus it is an excellent material for places subject to extreme temperature variations, such as cold storage.
Q2: Can we comply with international flame retardant standards?
We have flame-retardant grades in stock and we can offer formulations based on the project specifications.
Q3: Does it fit with the existing plant?
It is completely compatible and most of the existing equipment will not require any changes.
Q4: Will the form be altered after a long-term stay in a cold storage at low temperature?
No, Our graphite EPS is homogeneous foamed and has a stable structure so it will not be affected by low temperature or moisture.
Q5: Is it possible for us to get a small order for samples?
A: Yes, we welcome sampling, mold testing, and foaming trials.
