In What Environment Can Rotomolded Products Be Used?
Rotational molded products can withstand a variety of harsh environments due to their unique manufacturing processes and material properties. Specifically, rotomolded products can withstand the following types of harsh environments:
1. High and low temperature environments
High-temperature environments: Rotational molded products, especially those made from high-temperature-resistant materials such as high-density polyethylene, can withstand higher temperatures. The high application temperature of high-density polyethylene can reach 100°C, allowing rotational molded products to maintain stability and durability in high-temperature environments.
Low temperature environment: Some rotational molded products, such as rotational molded military boxes, can be shipped by sea to places with low temperatures of -55°C, indicating that they have good low temperature resistance. This characteristic allows rotomolded products to be used normally in cold areas or extreme weather conditions.
2. Corrosive environment
Rotomolded products, especially those used in storage tanks and water tanks in the chemical industry, often have excellent corrosion resistance. Plastic materials, such as polyethylene, are resistant to most chemicals, so rotomolded products perform well in corrosive environments such as chemical plants and wastewater treatment plants.
Their corrosion resistance is not limited to common acid and alkali substances, but also includes a variety of organic solvents and chemicals. This is due to the smoothness and low friction of the plastic material surface, which reduces chemical reactions and wear with other substances.
3. Humid and underwater environments
Rotational molding products have good waterproof properties and can effectively prevent moisture penetration and leakage. This property makes rotomolded products particularly suitable for wet environments and underwater applications, such as equipment in swimming pools, aquariums and marine engineering.
The seamless one-piece molding process ensures the sealing of the rotomolded product, further improving its durability and safety in the underwater environment.
4. Harsh weather conditions
Rotational molding products usually have good weather resistance and can withstand various climatic conditions, such as strong wind, heavy rain, sun exposure, etc. This characteristic makes rotomolded products excellent in outdoor applications, such as outdoor water storage facilities, agricultural irrigation systems, etc.
5. Physical impact and collision
Rotational molding products have high impact resistance and can withstand a certain degree of physical impact and collision without being easily damaged. This feature makes rotational molded products safer and more reliable during transportation, handling and installation.
To sum up, rotational molding products can withstand a variety of harsh environments by virtue of their high temperature resistance, low temperature resistance, corrosion resistance, waterproof and moisture resistance, and weather resistance. This makes rotational molding products widely used in various fields, such as chemical industry, agriculture, military, outdoor facilities, etc.
