News - SILIKE Introduces Soft Modified TPU Particle 3135 to Enable Stable Matte Finish and High-Performance TPU Film Surfaces

Stable matte TPU film enabled by 3135 technology.

TPU film matte technology is becoming increasingly important in high-performance film manufacturing, where both aesthetic appearance and processing stability are required. Traditional matte solutions often rely on surface coatings or mineral fillers, which may lead to migration, inconsistent gloss levels, or reduced long-term durability.

SILIKE silicone modified TPU particle technology provides a structural approach to TPU film surface modification, enabling stable matte finish, improved anti-blocking performance, and reliable extrusion behavior without compromising material flexibility.

SILIKE has highlighted its Soft Modified TPU Particle 3135 as an advanced material solution designed to enable stable matte surface control, improved processing stability, and enhanced tactile performance in TPU film systems. The technology responds to increasing industry demand for premium surface aesthetics and reliable large-scale TPU film production.

As TPU films continue to expand across packaging, automotive interiors, consumer electronics, and flexible functional materials, manufacturers are facing growing pressure to balance optical appearance, processing efficiency, and long-term surface stability. According to recent industry reporting, TPU films are increasingly used in applications such as automotive interior components, acoustic systems, and flexible functional laminates due to their durability and design adaptability.

At the same time, new developments in TPU film technologies—particularly in printed electronics and automotive haptics—are accelerating demand for materials that deliver both functional performance and consistent surface aesthetics. Recent collaborations in the automotive sector highlight TPU films as key substrates for next-generation flexible interior systems integrating sensing, touch control, and adaptive interfaces.

Structural Approach to Matte TPU Surface Design

SILIKE’s Soft Modified TPU Particle 3135 adopts a structural modification approach based on silicone elastomer dispersion within a TPU-compatible polyester carrier system. Instead of relying on surface coatings, external fillers, or migrating slip agents, the technology modifies the internal micro-phase structure of TPU during processing.

This structural design enables controlled light scattering within the material matrix, resulting in a stable matte appearance that is intrinsic to the TPU film rather than applied externally. The system is designed to maintain surface consistency during continuous extrusion and roll-to-roll processing.

Key Functional Characteristics (Based on Product Design)

According to SILIKE’s product design framework, Soft Modified TPU Particle 3135 is engineered to deliver:

Stable matte surface appearance in TPU film systems
Improved surface touch perception with reduced stickiness
Non-migrating performance stability
Enhanced anti-blocking behavior in film winding processes
Compatibility with TPU extrusion and film processing systems

The material is supplied in pellet form and designed for direct incorporation into TPU processing workflows without the need for additional surface treatment steps.

Industry Challenges Driving Adoption

Traditional matte TPU film solutions often rely on mineral fillers, coatings, or external additives. However, these approaches can introduce trade-offs such as surface degradation, inconsistent gloss levels, or additive migration over time.

In contrast, structural modification technologies are gaining attention as the industry shifts toward long-term performance stability and scalable manufacturing efficiency. Recent technical discussions in polymer processing highlight that TPU film surface quality is increasingly dependent on formulation-level control rather than post-processing treatments.

Application Expansion in TPU Film Markets

Soft Modified TPU Particle 3135 is designed for TPU film applications where both visual quality and functional reliability are critical, including:

Functional TPU films
Flexible packaging films
Industrial protective films
Laminated and composite TPU film systems
High-end surface design films requiring matte aesthetics

The growing TPU film market, projected to expand steadily through 2030s driven by automotive, electronics, and packaging sectors, is reinforcing demand for advanced surface engineering materials capable of delivering stable aesthetics under industrial-scale production conditions.

From Surface Treatment to Material-Level Design

SILIKE emphasizes that Soft Modified TPU Particle 3135 represents a shift from traditional surface modification methods toward material-intrinsic surface engineering. By integrating matte effect formation into the TPU matrix itself, manufacturers can reduce reliance on coatings and improve consistency in high-volume production environments.

Test Data & Performance Validation

To evaluate the performance of Soft Modified TPU Particle 3135 in TPU film applications, SILIKE conducted a comparative film extrusion test using a standard formulation. In the evaluation, 10% of 3135 was uniformly blended with polyester TPU, followed by direct casting to produce a 10-micron TPU film. The resulting samples were then analyzed for key optical and surface performance indicators, including haze, light transmittance, and surface gloss, and compared against a conventional matte TPU material.

The results demonstrate that the incorporation of 3135 effectively modifies the internal micro-phase structure of TPU, enabling a more controlled light scattering behavior that contributes to a stable matte surface appearance. At the same time, the material maintains good processing compatibility in standard melt blending and extrusion systems without requiring additional granulation steps. According to SILIKE’s technical data, the product is designed with a Shore A hardness of 85 and a polyester TPU carrier system, supporting balanced mechanical integrity while enhancing surface aesthetics and anti-blocking performance. These results confirm its suitability for high-consistency TPU film production where both visual uniformity and processing stability are critical.

SILIKE is a materials technology company specializing in silicone-based polymer modification systems, including functional masterbatches and elastomeric additives designed to improve processing performance, surface quality, and durability across TPU, plastics, and engineered polymer systems.

Soft Modified TPU Particle 3135 represents a significant step forward in TPU film surface engineering by integrating matte appearance control, soft-touch enhancement, and non-migrating structural stability within a single material system. By shifting from traditional surface treatments to internal micro-phase design, SILIKE provides manufacturers with a more consistent and scalable approach to achieving premium TPU film aesthetics. As demand continues to grow for high-performance, visually refined, and process-stable TPU films across automotive, packaging, and consumer applications, this technology offers a practical pathway toward more reliable and design-driven material solutions in advanced polymer processing.
