At Ultra Limited for Industrial Development, calcium carbonate offers an innovative solution for improving the safety and performance of cable manufacturing. Traditionally, cable sheaths were made using PVC plastics, which, while durable, are flammable and release toxic gases when exposed to fire—posing a serious risk to human safety. Incorporating calcium carbonate into cable formulations addresses these challenges effectively.

Calcium carbonate is a non-toxic, odorless, and tasteless material that is environmentally friendly and safe for manufacturing. With a high thermal decomposition temperature of over 800°C, it significantly improves fire resistance in cable sheaths. In contrast, standard plastics typically ignite at around 400°C. This means that in the early stages of a fire, calcium carbonate does not decompose into harmful gases, ensuring a safer environment and reducing risks.

Beyond its fire-resistant properties, calcium carbonate offers significant economic advantages as a cost-effective filler. By reducing the reliance on more expensive raw materials, it lowers production costs without compromising the quality or durability of the cables. Additionally, calcium carbonate enhances the mechanical properties of the cable sheath, providing strength and stability while maintaining flexibility.

At Ultra Limited, we provide a range of high-purity calcium carbonate products tailored for cable manufacturing. Our solutions help manufacturers create safer, more cost-efficient cables that meet modern safety and environmental standards. Whether for fire-resistant cables or standard applications, our calcium carbonate ensures reliable performance and sustainability.
