Limitations of Conventional Matte Additives for TPU Cable

TPU (Thermoplastic Polyurethane Elastomer) is a commonly used material for cable protective sheathing in the market. In application, surfaces of cables and other products often require a certain matte finish. This matte effect enhances the product's premium feel and visual comfort. Functionally, it provides improved anti-slip properties and enhances wear resistance. In some scenarios, it can also reduce interference caused by light reflection.

To achieve this matte finish on TPU products, additives with low compatibility, significantly different melt flow indices, or varying plasticizing temperatures are typically incorporated into the polymer, while requiring precise control over the processing conditions. Common additives include grafted rubber, PS (Polystyrene), and inorganic fillers. However, these conventional matting agents often require very low processing temperatures, which can result in cables with poor abrasion and scratch resistance. Furthermore, improper process control or extended processing times can cause inconsistencies or variations in the final matte effect.

Discover How Si-TPV Provide Durable Finish & Skin-Friendly Feel for TPU Cables

Addressing the these challenges, SILIKE introduces its innovative matting agent—the Matte Finish Additive Si-TPV 2335-65A This specialized material utilizes unique compatibility technology and dynamic vulcanization to uniformly disperse fully vulcanized silicone rubber into the TPU matrix as fine 1-3µm particles, forming a distinct sea-island structure. The incorporation of silicone rubber effectively resolves traditional TPU issues such as sticky surface feel, plastic-like texture, and cheap glossy appearance.

It forms a uniform and fine matte coating on the cable surface, delivering a durable and high-end matte finish that successfully eliminates the plastic-like feel and cheap gloss associated with conventional TPU cables. This significantly enhances both the tactile quality and visual premiumness of the product. Simultaneously, it imparts a silky-smooth, dry, and long-lasting skin-friendly feel to the cables. Even during prolonged holding or skin contact, it maintains comfort while preventing any sticky sensation caused by moisture or sweat.

Easy-Processing Advanced Matte Additive with Enhanced Performance

In terms of performance, this product utilizes a unique vulcanization and cross-linking technology to ensure no migration or tackiness during long-term use, fundamentally addressing common issues such as oil exudation and dust attraction on the surface of ordinary TPU cables after prolonged use, thereby maintaining long-lasting cleanliness. Furthermore, due to its special cross-linked network structure, it forms a robust protective layer on the TPU surface, significantly enhancing the abrasion resistance of TPU products. This effectively reduces scratches caused by daily friction and dragging, greatly extending the service life and preserving the aesthetic appeal of the cables.

On the production and processing side, this product offers the distinct advantage of simple processing. It is available in a directly-addable grade, requiring no pelletization, complex equipment modifications, or demanding processing conditions. It can be seamlessly integrated into existing production lines, substantially improving production efficiency and product yield. It is an ideal choice for achieving high-end, functional upgrades for TPU cables
