ROTUBA H2 Cellulose Acetate

ROTUBA H2 Cellulose Acetate is a classic thermoplastic cellulose organic acid ester, synthesized by acetylation with acetic anhydride and presented as powder. It balances rigidity and toughness, has high selectivity of porous membrane, suitable for injection molding, extrusion and other molding processes. It meets the comprehensive requirements of toys, packaging

Features Of ROTUBA H2 Cellulose Acetate

  1. Precise Separation and Permeability - The porous structure has high selectivity and large water permeability, suitable for filtration and separation scenarios, ensuring separation accuracy and efficiency.

  2. Balanced Rigidity and Toughness - Tensile strength of 33.1MPa, flexural strength of 51.7MPa, elongation rate of 35%, suitable for various structural part molding.

  3. Efficient Molding Adaptability - Good melt fluidity, suitable for injection molding/extrusion/thermoforming, shortening production cycle and reducing processing cost.

  4. Stable Environmental Resistance - Water absorption rate of 2.3%, load deformation at 50℃ is only 1%, stable size after molding, suitable for various working conditions.
