Density is an easily overlooked parameter in TPE raw materials, ranging from 0.3 g/cm³ in foamed grades to 2.0 g/cm³ in highly filled grades. It affects product weight, material cost, elasticity, tensile strength, and wear resistance. Understanding which density range fits which application helps narrow down material selection.

Since new energy equipment is often exposed to outdoor conditions for long periods, soft rubber components need to provide sealing, cushioning, and weather resistance. This article reviews how TPE products are used in four application areas: charging stations, energy storage, photovoltaics, and new energy vehicles. It also highlights the key specifications to verify during material selection.

When customizing TPE materials, one trade-off is hard to avoid. To achieve a softer feel, more oil must be added. However, the more oil added, the harder it becomes to maintain strength, resilience, and long-term stability.

From traditional vulcanized rubber to PVC, and now to TPE raw materials, every shift reflects the manufacturing industry’s reevaluation of performance, environmental sustainability, and cost. When discussing whether TPE materials are worth recommending, the focus is not on a specific polymer alone, but on a material solution that balances elasticity, processing efficiency, and compliance.

A high or low MFI does not directly indicate the quality of the material. Rather, it determines which molding methods and product structures the material is suitable for. If the compatibility between the MFI and the molding process is overlooked during material selection, avoidable problems may occur during injection molding.

As a thermoplastic material, TPE granules are relatively sensitive to temperature. Its temperature resistance is not a fixed value but rather a comprehensive indicator determined by its chemical structure, formulation, processing methods, and operating environment. Understanding these influencing factors helps make more appropriate decisions during the material selection and process design stages.
