Triacetate Cellulose: A High-Performance Polymer for Films & Textiles
Triacetate Cellulose (CTA) is a modified cellulose polymer derived from natural wood pulp or cotton linters, where at least 92% of the hydroxyl groups are replaced with acetyl groups. This makes it more heat-resistant, durable, and chemical-resistant than regular cellulose acetate. It is widely used in optical films, textiles, and specialty applications.
🌟 Key Properties of Triacetate Cellulose
✅ High Transparency – Ideal for optical applications like LCD screens and polarizing films.✅ Excellent Heat Resistance – More thermally stable than standard cellulose acetate.✅ Chemical & Moisture Resistance – Resistant to acids, oils, and solvents, making it durable in various environments.✅ Dimensional Stability – Maintains its shape and structure under different conditions.✅ Biodegradable & Sustainable – Derived from renewable plant sources, making it an eco-friendly alternative to synthetic polymers.
