Which technical coatings are best suited for filler application processes in the textile industry?
Sofiplast provides anti-abrasion and anti-clogging technical coatings for equipment handling mineral fillers, pigments, conductive additives, and flame-retardant materials used in technical textile production. These treatments help reduce wear on hoppers, screw conveyors, metering rollers, and duct systems while limiting buildup, improving material flow, and optimizing production efficiency.
In technical textile processes involving the addition of fillers or additives, equipment is exposed to demanding operating conditions caused by the continuous handling of powdered and granulated materials. These substances can generate adhesion, abrasion, and clogging issues, particularly on hoppers, screw conveyors, dosing rollers, and conveying systems.
Without suitable protection, these operating conditions may lead to dosing irregularities, material loss, premature equipment wear, and frequent production downtime. High-performance technical coatings are therefore essential to ensure smooth material flow, facilitate cleaning operations, and improve equipment durability.
Coating solutions for filler application equipment in the textile industry
Technical coatings and anti-abrasion solutions for filler application processes
In technical textile filler application systems, equipment is continuously exposed to abrasive materials such as mineral powders, flame-retardant additives, and pigments. The continuous flow of these substances accelerates surface wear, affecting equipment precision, reliability, and lifespan.
To effectively protect these critical areas, Sofiplast offers anti-abrasion coatings such as:
- Fluoropolymer coatings reinforced with PEEK additives (Victrex®)
These treatments provide excellent wear resistance, even in the presence of highly abrasive fillers, while maintaining strong chemical and thermal stability.
Technical coatings and anti-clogging treatments for filler addition processes
Clogging is a common issue in filler application systems used in technical textile production, especially when handling fine, hygroscopic, or slightly sticky materials. Progressive buildup inside hoppers, ducts, screw conveyors, and nozzles can disrupt material flow, causing dosing irregularities, unplanned downtime, and increased cleaning requirements.
To prevent these issues, Sofiplast applies anti-clogging coatings such as:
- Fluoropolymers (FEP or PFA, known under the trademarks Teflon® or Xylan®).
These treatments create an ultra-smooth, non-stick surface that prevents particles from adhering to internal equipment surfaces. The result is smooth and consistent material flow, significantly reduced buildup, fewer cleaning operations, and improved production efficiency.
Our eco-friendly stripping processes
Equipment used in filler application processes, including mineral, pigment, conductive, and flame-retardant additives operates under demanding conditions involving mechanical abrasion, persistent buildup, and progressive clogging. To protect these critical areas, Sofiplast develops technical coatings designed to withstand the harshest operating environments.
Before applying these treatments, we work with you to define the most suitable eco-friendly stripping process for your operating requirements.
This method uses natural, reusable plant-based media such as corn starch, wheat, and fruit shells, ensuring effective surface preparation without the need for aggressive chemical solutions. This approach preserves component geometries while ensuring optimal coating adhesion and long-term treatment performance.
