At present, the use of rotational molding mobile toilets is becoming increasingly widespread, and its presence can be seen in both cities and tourist attractions. In this issue, we will introduce the advantages of rotational molding mobile toilets!

At present, the intelligent power grid project is flourishing, and the construction of distributed power stations is also vigorously promoted, which puts forward higher requirements for the electrical safety performance of high-voltage cable joints. The original conventional coating materials can no longer meet the higher performance requirements of flame retardancy and voltage breakdown resistance.

On August 7, 2025, our company officially signed a cooperation agreement with Xingzhi College of Zhejiang Normal University to jointly establish a practical education base, marking a solid step forward for both sides in deepening the integration of industry and education and collaborative education.Ruitang Technology has joined hands with Zhejiang Normal University Xingzhi College to jointly build a practical education base, opening a new chapter in the integration of industry and education On August 7, 2025, our company officially signed a cooperation agreement with Xingzhi College of Zhejiang Normal University to jointly establish a practical education base, marking a solid step forward for both sides in deepening the integration of industry and education and collaborative education.

Rotomolding HDPE, short for rotationally molded high-density polyethylene, is a specialized thermoplastic material used in the production of large, seamless, and durable hollow products. The rotomolding process involves heating powdered HDPE resin inside a rotating mold, ensuring even material distribution and the formation of stress-free structures. This technique has gained immense popularity across industries such as automotive, agriculture, marine, and chemical storage due to its ability to produce complex shapes with exceptional strength and longevity.

Among rotomolding materials, Nylon 12 (PA12) stands out with its unique performance combination. As a key member of the long-carbon-chain nylon family, Nylon 12 features longer molecular chains and lower amide bond density, resulting in an extremely low water absorption rate of approximately 0.25% — the lowest among all nylon products. Additionally, it boasts low density, excellent low-temperature toughness, and outstanding oil and chemical resistance. It maintains good toughness even in extreme cold environments as low as -70°C, with a long-term service temperature reaching 80-90°C.
