ROTUBA CP808 Cellulose Acetate

ROTUBA CP808 (12% Plasticizer) Cellulose Acetate Propionate is a high - quality thermoplastic cellulose organic acid ester, synthesized by acetylation and propionylation, presented as powder. It has balanced medium toughness and rigidity, with Izod notched impact strength of 350J/M and water absorption rate of only 1.5%, suitable for injection molding, extrusion and other molding processes.

Features Of ROTUBA CP808 Cellulose Acetate

  1. Balanced Medium Toughness & Impact Resistance - Izod notched impact strength of 350J/M, shatter - resistant and not easy to break, suitable for packaging and thin - walled parts, improving use safety and durability.

  2. Low Water Absorption & Dimensional Stability - Water absorption rate of 1.5%, not easy to deform after molding, suitable for precision parts and sealing components, ensuring assembly accuracy and appearance consistency.

  3. Efficient Molding Processing - Powder form for easy dispersion, suitable for injection molding, extrusion and thermoforming, helping efficient mass production of complex structural parts and thin - walled parts.

  4. Stable Mechanical Performance - Tensile strength at break of 34.5MPa and flexural modulus of 1170MPa, balanced rigidity and toughness, suitable for structural and appearance parts in various scenarios
