Si-TPV 3510-65A Thermoplastic Silicone Elastomer: Soft Touch, Anti-Slip Grip, and Durable Material for Wearable Devices

Rising Demand for Human-Centered Materials in Wearable Technology

The evolution of smart devices is shifting from pure functional innovation toward human-centered design experiences. Consumers increasingly expect wearable devices, portable electronics, and sports equipment to deliver not only advanced functions but also superior comfort, premium aesthetics, and long-lasting durability.

According to IDC’s Worldwide Wearable Device Tracker, global wearable device shipments reached 145.7 million units in Q1 2026, representing year-over-year growth, with hearables maintaining strong demand while smart glasses and smart rings continued emerging as important growth categories.(Source from IDC Wearable Devices Market Insights)

At the same time, wearable technology development is facing new material challenges. Recent research highlights that next-generation flexible wearable electronics require materials that can balance softness, durability, flexibility, skin comfort, and long-term reliability.(Source from Emerging thermal management strategies for flexible wearable device - ScienceDirect)

Traditional elastomers such as conventional TPU, TPE, and silicone rubber often involve trade-offs:

TPU provides strength and abrasion resistance but may lack premium soft-touch performance.
Traditional TPE materials can experience surface aging, stickiness, or reduced tactile quality over time.
Silicone offers excellent softness but presents challenges in processing efficiency and recycling compatibility.

To address these challenges, SILIKE introduces Si-TPV 3510-65A Thermoplastic Silicone-Based Elastomer, a high-performance material designed to combine silicone-like comfort with thermoplastic processing advantages.

What Is Si-TPV 3510-65A?

Si-TPV 3510-65A is a dynamic vulcanized thermoplastic silicone-based elastomer (TPV silicone elastomer) developed through advanced compatibility technology.

Its unique sea-island microstructure integrates:

A thermoplastic TPU continuous phase for mechanical strength and processing flexibility;
Cross-linked silicone rubber particles dispersed as the soft phase for enhanced tactile properties and surface performance.

This innovative structure enables Si-TPV 3510-65A to deliver:

Premium soft-touch feel;
Skin-friendly comfort;
Excellent dry and wet grip performance;
High abrasion resistance;
Long-term surface stability;
Thermoplastic processing capability.

Unlike silicone rubber, Si-TPV can be processed using conventional thermoplastic manufacturing methods, including injection molding and overmolding, helping manufacturers simplify production while achieving advanced material performance.

Solving Key Material Challenges in Wearable Devices and Consumer Electronics

1. Premium Soft Touch Material for Enhanced User Experience

2. Anti-Slip Grip Material for Sports and Ergonomic Applications

3. Long-Term Surface Stability Without Plasticizers or Softening Oils

Modern consumers interact with devices through direct skin contact every day. Smartwatch straps, fitness trackers, earbuds, and handheld devices require materials that feel comfortable during extended use.

Si-TPV 3510-65A provides:

Silky smooth surface texture;
Soft and comfortable touch;
Skin-friendly wearing experience;
Stable tactile performance after long-term use.

Compared with coated soft-touch solutions, Si-TPV 3510-65A achieves its soft feel through material structure rather than surface coating, helping reduce concerns related to coating wear, peeling, or tactile degradation.

Supporting Sustainable and Durable Product Design Trends

Material durability has become increasingly important as industries move toward longer product lifecycles.

The European Commission’s Joint Research Centre has highlighted growing concerns around electronic waste and the importance of improving product lifespan, repairability, and resource efficiency.(Source from Why repairability matters for the future of tech products - Joint Research Centre)

For manufacturers, selecting durable soft-touch materials can help:

Extend product service life;
Maintain premium user experience;
Reduce premature material replacement;
Support more sustainable product development strategies.

Si-TPV 3510-65A provides a material pathway for brands seeking a balance between performance, aesthetics, processing efficiency, and durability.
