China LLDPE Manufacturer, Supplier, Factory

At present, customers use mold etching, silk screen printing, spray painting, and in mold transfer printing methods to produce company logos, but they are not firm and easy to fall off. To solve this problem, you can try our company's laser marking PE rotational molding material!

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 the afternoon of January 18, 2025, Zhejiang Rotoun Plastic Technology Corp held a significant board meeting, attended by all board members and subsidiary general managers, aimed at reviewing past work, planning future development directions, and jointly exploring Zhejiang Rotoun Plastic Technology Corp's response strategies in the complex and ever-changing market environment.

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. This cooperation aims to fully leverage the respective advantages of the school and the enterprise to create a high-quality platform that closely integrates industry, academia and research.

Linear low-density polyethylene (PE-LLD) was selected as the base material. The melt blending was carried out by a twin-screw extruder, and the powder material suitable for rotational molding process was prepared by using a mechanical grinding mill.

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.
