Roto moulding, or rotational moulding, is a growing manufacturing technique in India, known for producing durable and hollow plastic products like water tanks and storage containers. As the demand for lightweight, cost-effective, and durable plastic products increases, manufacturers are constantly exploring materials and additives that improve product performance and manufacturing efficiency. One of the most critical components in this process is the blowing agent.
In this article, we’ll explore the significance of blowing agents in roto moulding, how Indian manufacturers are innovating in this space, and why DPL Group of Companies stands out as a leading blowing agent manufacturer in India for roto moulding products.
What Are Blowing Agents in Roto Moulding?
Blowing agents are substances that produce a cellular structure through a foaming process in materials like plastics and rubber. In roto moulding, they help create lightweight, thermally insulating, and structurally sound products. These agents decompose under heat and release gases that expand the plastic material, leading to the formation of foam-like structures inside the product.
They are widely used in the manufacturing of:
● Roto Moulding Water Tanks
● Insulated Containers
● Hollow Plastic Goods
● Custom Industrial Moulded Products
Why India Needs Advanced Blowing Agents for Roto Moulding
India’s manufacturing sector has rapidly adopted roto moulding for both industrial and domestic applications. As the market grows more competitive, there’s a higher demand for:
● Reduced material cost per unit
● Lighter product weight
● Improved insulation (especially for water tanks and containers)
● Eco-friendly and safe production processes
To meet these requirements, manufacturers turn to advanced chemical blowing agents that provide:
● Uniform foam distribution
● Stable gas generation
● Controlled decomposition temperatures
This is where Indian innovation plays a crucial role.
Trends & Preferences for Blowing Agents
Today, Indian roto moulders prefer blowing agents that are:
● Environmentally safe
● Thermally stable
● Consistent in batch quality
● Compatible with polymers like polyethylene and PVC
Among the different types of blowing agents, endothermic blowing agents are becoming increasingly popular due to their cleaner decomposition process and minimal impact on moulding equipment.
Companies like DPL Group of Companies have been instrumental in offering reliable blowing agent solutions that cater to these specific needs.
