In fact, oil bleeding is not a failure of the material’s structure, but rather a physical phenomenon caused by the migration of low-molecular-weight components in the TPE formulation to the surface. When such problems arise, experienced TPE manufacturers address them at the formulation level by adjusting the white oil and additive systems to reduce surface migration.

In product categories with high softness requirements—such as yoga mats, shoe materials, and anti-slip mats—ultra-soft foam has long been a popular choice for material selection. In the past, EVA dominated this field, but in recent years, elastic TPE foam has been rapidly gaining ground. This isn’t because it’s cheaper, but because it offers an experience that EVA struggles to match in three key areas: tactile feel, resilience, and environmental friendliness.

During TPE wire extrusion, material buildup in the die and surface roughness are common issues that recur frequently in mass production. The causes of these problems are often multifaceted, involving an interplay of material, process, and mold factors. Adjusting a single aspect may provide temporary relief, but it is difficult to eliminate the problem completely.

Products such as bicycle handlebar grips, pull tubes, and diving goggles all benefit from their eco-friendly, soft, and highly resilient properties. However, after prolonged use, issues such as a sticky surface, hardening, fading, and even cracking often occur—this is due to material aging.

The formulation design of high-temperature TPEs is not simply a matter of combining raw materials; rather, it is a systematic process that balances molecular structure control, chemical protection, and physical reinforcement.To scientifically select the most suitable solution, you can proceed step by step across four dimensions. In this article, Zhongsu Wang’s editorial team shares these insights with you.

In an era of accelerating material innovation, Thermoplastic elastomer is gradually replacing traditional PVC and rubber as the preferred choice for many manufacturers and engineers thanks to its unique balance of properties. It effectively combines the high elasticity of rubber with the efficient processability of plastics, setting a new industry standard for compliance and tactile experience.
