Process: Biaxial stretching functional film manufacturing technology
Width: 100 cm (customizable upon customer requirements)
Roll length: 20 m per roll (customizable upon request)

Product Features
Realize cooling without electricity, with excellent properties of ultra-high molecular weight popolyethylene.
It provides high-efficiency waterproof performance simultaneously and features convenient construction.

The radiation cooling film is particularly suitable for color steel roof,container house,the roof and body of the truck for countries with hot climates
1. Radiation cooling, passive cooling, without electricity. It can lower the indoor temperature by more than 10 degrees.

2. Strongly adheres to the metal surface, preventing moisture and air from penetrating. Protects the metal surface of the color steel sheet, extending its service life by more than 10 years. Saves the cost of replacing the color steel sheet roof and avoids affecting production in the workshop during the replacement process.

3. Made of ultra-high molecular polyethylene, it has excellent waterproofing performance, long-lasting waterproofing effect, and can resist aging with a long service life.

4.It has its own thickness. The butyl rubber and ultra-high molecular polyethylene have good elasticity, which can effectively reduce the noise caused by raindrops hitting the roof during rain.

Simulated Performance Study (Radiative Cooling Film)

Radiative cooling is a passive, zero-energy consumption technology that achieves cooling by directly emitting heat from an object as electromagnetic waves at specific wavelengths into outer space—the “ultimate heat sink.”

Workflow of Radiative Cooling Products:
Block Heat Absorption High-Efficiency Radiation Traverse the Atmosphere
Continuous Cooling
The radiative cooling film highlighted by Huacheng Hi-Tech adopts passive radiative cooling technology. Its working principle consists of two core processes:
First, the high-reflectivity layer reflects sunlight, especially near-infrared thermal radiation, back into the atmosphere, with a reflectance of over 90%.
Second, through the 8–13 μm atmospheric window, the surface heat of objects is directly dissipated into the cold outer space in the form of mid-infrared radiation.
Actual test data shows that under typical daytime conditions, this film can lower the surface temperature of covered objects by 15–30℃ compared with the ambient temperature.
The whole cooling process requires no power supply, no refrigerants and no moving components. It serves as a continuous cooling method with zero energy consumption.

Application Scenarios
Cooling for granaries, mobile base stations and petrochemical storage tanks.
Suitable for temperature reduction of various buildings and storage tanks.

Industrial Buildings

Reduces air conditioning energy consumption
Commonly achieves 20%-40% savings on air conditioning electricity
Extends the service life of air conditioning euipment
Reduces operating hours and wear, significantly extending service life

Civil Buidlings

Enhance Indoor Comfort and Build Green Cities
An office buidling of 100,000 square meters can incur annual electricity costs of up to 10 million yuan. The carbon dioxide emissions generated by urban cooling are substantial, making energy-efficient building cooling a key factor in the development of green cities.

Special Facilities
Airport：

Reduces air conditiong energy consumption in area such as boarding bridges, enhances comfort, and slows equipment aging.

Data Center：

Lowers cooling costs, improves thermal management reliability, and addresses high heat density challenges.

Hospital：

Equipment Heat Dissipation

Outdoor cabients in power, telecommunications, and energy storage industries are often exposed to prolonged direct sunlight, leading to equipment failure and aging. By applying radiative cooling products, internal temperatures can be reduced, condensation can be prevented, and equipment can be effectively protected.
