Rotational molding is a versatile manufacturing process that allows for the creation of a wide variety of plastic products, including battery boxes, water tanks, oil tanks, and other containers. One of the most commonly used resins in rotational molding is polyethylene, a type of thermoplastic polymer known for its excellent properties, including resistance to impact, weathering, and chemicals. In this article, we will explore the characteristics of polyethylene in rotational molding, the types of polyethylene used, and the powders used in the process.

What Type of Powder is Used in Rotational Molding?
In rotational molding, the powder used is typically a fine particle size resin that can be easily melted and distributed throughout the mold. The powder must also have a consistent particle size distribution and be free of any contaminants or foreign particles that could affect the final product’s quality. Roto Dynamics, an experienced rotomolding company, uses only the highest quality powders in their rotational molding process, ensuring consistent quality and performance in their plastic products.
What are the Characteristics of Polyethylene in Rotational Molding?
Polyethylene is a popular choice for rotational molding due to its excellent properties. It has good impact resistance making it ideal for producing durable products such as water tanks and oil tanks. Polyethylene is also resistant to most chemicals, including acids and alkalis, and is resistant to UV radiation, making it suitable for outdoor use. In addition, it is easy to mold and can be made into complex shapes, making it an ideal material for rotational molding.
What Types of Polyethylene are Used in Rotational Molding?
There are several types of polyethylene used in rotational molding, including low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and high-density polyethylene (HDPE). LDPE is the most commonly used polyethylene in rotational molding due to its flexibility, toughness, and ease of molding. LLDPE is similar to LDPE but has higher strength and puncture resistance, making it ideal for applications that require greater durability. HDPE is a stiffer and more rigid polyethylene than LDPE or LLDPE and is commonly used in applications where greater stiffness and rigidity are required.
The Advantages of Using Polyethylene in Rotational Molding
Using polyethylene in rotational molding offers several advantages over other plastic manufacturing techniques. The process allows for the creation of complex shapes and designs, making it ideal for creating unique and customized products such as water tanks and oil tanks. Polyethylene is also lightweight and durable, making it ideal for outdoor use. Additionally, it is a cost-effective material, allowing for the production of large or small quantities of products at a low cost.
Conclusion
In conclusion, polyethylene is a versatile and cost-effective material for rotational molding that offers excellent physical and chemical properties. There are several types of polyethylene resins available, each with its unique characteristics and properties.
