In 2026, the demand for TPE materials in the automotive industry will continue to grow, driven by vehicle interior upgrades and the rapid development of new energy vehicles.
Major application areas include:
Soft-touch interior components such as steering wheels and dashboards
Door, window, and lighting sealing systems
New energy vehicle cable and wire protection
Battery pack sealing components
These applications require materials that can provide better comfort, durability, and safety performance.
TPE materials for automotive applications are expected to meet several critical requirements:
Low VOC and low odor performance to comply with stricter automotive interior standards
Excellent weather and aging resistance for long-term performance under temperature changes, UV exposure, and ozone conditions
Low compression set to maintain sealing performance over long service periods
Strong adhesion with PP, ABS, and other substrates for over-molding applications
Good chemical and wear resistance against oils, coolants, and daily environmental exposure
SEBS used in automotive TPE applications requires a balanced combination of elasticity, processability, and durability.
Key considerations include:
Low volatile components and low odor characteristics
Optimized styrene content and molecular structure to achieve different hardness and bonding requirements
Suitable molecular weight and structure design for soft-touch applications, sealing parts, and durable components
Excellent compatibility with fillers and additives used in automotive formulations
With the rapid development of humanoid robots and service robots, TPE materials are becoming increasingly important for human-machine interaction.
Main applications include:
Bionic skin
Joint over-molding
Soft robotic grippers
Foot cushioning systems
The key objective is to provide a safer, more flexible, and more human-like interaction experience.
TPE materials for robotics applications require:
Soft touch and low modulus properties for human-contact applications
High elasticity and resilience to support repeated movement
Excellent dynamic fatigue resistance for long-term mechanical operation
Stable performance across a wide temperature range
Good compatibility with functional additives, including conductive or sensing materials
SEBS for robotics applications should provide:
