Characteristics of PFOS & PFOA-free PTFE Emulsion

As a professional manufacturer of PTFE high temperature fabrics, Jiangsu Aokai New Materials brings you professional introductions.

Against the backdrop of increasingly stringent environmental regulations, PFOS/PFOA-free PTFE emulsion is an upgraded product developed to replace traditional PFOA-containing polymerization processes. It maintains the core properties of PTFE while greatly enhancing environmental friendliness and health safety.

1. Eco-friendliness & Health Safety

Its most prominent advantage is the elimination of persistent organic pollutants such as PFOA used or remained in conventional production. Different from traditional emulsifiers like PFOA that are hard to degrade and persist in the environment for a long time, this new-type emulsion adopts eco-friendly surfactant systems which can degrade rapidly and avoid substance accumulation. Qualified products are widely applied in food-contact scenarios such as non-stick cookware coatings and fully comply with global food safety standards.

2. Retained Core PTFE Properties

● Superior non-stick & release performance: Extremely low surface energy and friction coefficient, capable of forming high-gloss coatings with excellent anti-stick and demolding effects.

●  Outstanding chemical inertness: Highly resistant to nearly all industrial chemicals and solvents with stable chemical properties.

●  Excellent thermal stability: Maintains stable performance across a wide temperature range.

●  Good dielectric property: Ideal insulating material for electrical insulation applications.

3. Stable Physical Properties

●  Appearance & system: Milky white liquid with PTFE micro/nano particles evenly dispersed in water via non-ionic surfactants.

●  Excellent storage stability: Long shelf life without easy stratification and low sedimentation rate, requiring no complicated stirring before use.

· Good process adaptability: Formulas can be adjusted flexibly per actual demands; featuring great wettability and permeability for efficient impregnation of porous substrates.

● Low residue & superior film-forming property: The adopted new surfactants leave minimal residue after curing, improving product purity and overall performance. Certain grades are specially formulated for uniform and full coating film formation.

4. Main Application Fields

● Non-stick coating: The most mainstream application, widely used for cookware, industrial mold anti-stick coating. Optimized models including 4DC-A1, 4DC-A2 and JF-4DCT deliver high gloss and strong adhesion.

● Material impregnation: Impregnate glass fiber, asbestos, metal parts and sealing fillers to improve chemical resistance, heat resistance and wear resistance.

● Additive for paints & inks: Effectively boost wear resistance and scratch resistance, and endow surfaces with smooth touch.

● Battery materials: Used as binder component in electrode slurry for lithium batteries.

● Special coatings & demolding: Applied for yarn coating, high-performance anti-corrosion & release coatings, and cast PTFE film production.
