Introduction: The Challenge of TPU Cable Jackets

TPU cable jackets are widely used in consumer electronics, wearable devices, and industrial cabling, offering flexibility, durability, and soft-touch aesthetics. However, manufacturers often face persistent challenges:

→ Matte surfaces turning glossy after extrusion

→ Micro-scratches appearing during winding or daily use

→ Blooming or additive precipitation reducing surface quality

→ Difficulty balancing surface appearance, wear resistance, and process efficiency

→ Achieving a stable matte finish while maintaining scratch and wear resistance is a top priority for R&D engineers in cable production.

TPU Engineers and  TPU compound formulators frequently search for solutions to questions like:

How to improve matte effect in TPU compounds?

What additives enhance scratch resistance without affecting surface finish?

Why do TPU cable jackets bloom over time?

How to achieve a durable matte surface in high-performance TPU applications?
SILIKE Matt Effect Masterbatch — A High-Performance Solution for TPU Compounds in Cable Jackets

SILIKE Matte Effect Masterbatch 3135 is a high-value functional matte additive formulated with TPU as the carrier.

SILIKE Matte Effect Masterbatch not only solves common matte stability and scratch issues but also ensures process efficiency and product aesthetics.

FAQ: How to Optimize TPU Matte Formulations？

Q1: How to prevent gloss drift in TPU cable jackets?
A1: Use a SIIKE TPU based Matte Effect Masterbatch to stabilize the surface microstructure and reduce friction during extrusion.

Q2: Why do TPU matte surfaces bloom or show white specks?
A2: Blooming often occurs due to migration of incompatible additives or oils. A well-formulated High-Performance Matt Flatting Agent ensures encapsulation and stability.

Q3: How to enhance scratch resistance without losing matte finish?
A3: Introduce wear-resistant micro-particles within a silicone-modified masterbatch to balance friction reduction and matte aesthetics.

Q4: What is the recommended dosage for SILIKE Matt Effect Masterbatch?
A4: Typically 1–10 wt% depending on TPU grade and desired matte effect. Pre-compounding ensures uniform distribution.

Q5: Can this Anti-blocking Matt Effect masterbatch be used in high-speed extrusion for cable jackets?
A5: Yes. It is designed to maintain surface consistency and avoid defects even under high shear and thermal stress.
