Embedded components; Material selection for inserts: 1. Good thermal conductivity; 2. Sufficient mechanical strength (details will be elaborated in the next section).

In the development history of rotational molding, there are two mainstream processing techniques, namely granulation process and dry mixing process. The overall process has significant differences, being two distinct pre-treatment methods for product processing materials.

With the global emphasis on energy conservation and emission reduction, plastic fuel tanks are gradually replacing traditional metal ones due to their light weight and high efficiency.

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.

Roto grade elastic materials have revolutionized industrial applications by offering superior flexibility, durability, and performance. In this article, we explore what makes Roto grade materials exceptional, their benefits across different industries, the technical specifications, comparisons with traditional materials, and how companies like Zhejiang Rotoun Plastic Technology Corp. are leading the market with innovative solutions.
