Name: ROTUBA CP808-12H-22034 SMOKE Cellulose Acetate Propionate
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of ROTUBA CP808-12H-22034 SMOKE Cellulose Acetate Propionate

Optimized smoke-modified formulation for enhanced thermal stability and reduced visible smoke generation during processing.
High compatibility with plasticizers and other cellulose esters, enabling uniform blending in multi-component thermoplastic systems.
Excellent film-forming capability with balanced melt viscosity for reliable extrusion and calendering performance.
Improved UV resistance compared to standard cellulose acetate grades, supporting extended outdoor service life in coated applications.
Low residual solvent content and controlled acetyl/propionyl substitution ratio for consistent rheological behavior and regulatory compliance.

Typical Applications Of ROTUBA CP808-12H-22034 SMOKE Cellulose Acetate Propionate

Smoke-suppressed thermoplastic films for protective packaging of sensitive electronics and medical devices.
Base resin for flame-retardant decorative laminates used in transportation interiors (e.g., bus, rail, aircraft cabin panels).
Carrier matrix in smoke-controlled release coatings for pharmaceutical tablet film coating and nutraceutical encapsulation.
Component in engineered blends for low-smoke, halogen-free wire & cable jacketing compounds.
Functional binder in specialty nonwovens requiring thermal stability and minimal pyrolysis smoke under elevated temperature exposure.
