The whitening that occurs on the surface of flame-retardant TPU products is caused by poor compatibility between low-molecular-weight flame retardants and the base material, leading to migration and leaching. Hydrolysis of polyester-based TPU, excessively high processing temperatures, or high-temperature storage environments can all accelerate this process. Using coated flame-retardant masterbatches can effectively block the migration pathway, thereby resolving the blooming issue at its source.
Flame-retardant TPE is rapidly replacing traditional PVC and rubber, becoming the preferred soft flame-retardant material for new energy cables, electronics & electrical appliances, and automotive parts industries. This article provides a detailed analysis of the core advantages of halogen-free flame-retardant TPE (customizable V-0 grade flame retardancy, eco-friendly and odorless, elastic hand-feel, easy processing and weather resistance), covering mainstream application scenarios such as cable jackets, EV charging station accessories, automotive interior seals, and flame-retardant components for home appliances—helping engineers and procurement professionals quickly grasp key selection criteria and industry trends.
Why does TPE flame retardancy always get stuck at V-2? Three main culprits: plasticizers are inherently flammable, the multiphase system lacks synergy, and flame retardants tend to migrate and bloom. A comprehensive analysis of TPE/TPU flame retardant selection challenges and processing pitfalls to avoid.
Why is TPE flame retardancy so challenging? Flammable plasticizers, inconsistent mechanisms across multiphase components, and flame retardant migration—seven pain points explained in one go. Understand the key criteria for selecting TPE/TPU flame retardants and avoid common pitfalls such as wire bloom, surface whitening, and processing difficulties.
