CAP is a crucial polymer cellulose ester that is made from cellulose acetate. It is a strong polymer with minimal to no odour that is also simple to process. Between cellulose acetate (CAc) and cellulose acetate butyrate (CAB) resins, CAP exhibits characteristics in the middle.
Its solubility and compatibility are more comparable to CAB than cellulose acetate, but it is tougher and more expensive.
Its performance characteristics are equivalent to those of cellulose acetate. Inks for printing, clear overprint varnishes, and topcoats for nail lacquers are the primary applications for CAP as a film former.
CAP is compatible with many other resins used in these goods and has excellent solubility in a variety of ink and coating solvents.
The Global EV Cellulose acetate propionate (CAP) market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A free-flowing powder with a mild scent is EastmanTM Cellulose Acetate Propionate CAP-482-0.5. Because of its high melting point, broad solubility in ink solvents, compatibility with other resins used in printing inks, and suitability for use in printing inks and transparent overprint varnishes, it is particularly suited for these applications.
Eastman CAP-482-0.5 produces films that are superior to those produced by other film-formers in terms of grease resistance, fast solvent release, and outstanding antiblocking capabilities.
The CAP-482-0.5 resin works well as a topcoat for manicure lacquer because of its solubility and hardness. To maximise the formulation’s stiffness, it is frequently used in conjunction with Eastman CAP-482-20. It produces a transparent, colourless solution when CAP-482-0.5 is dissolved in the proper solvents.
Cellulose is one of the most plentiful natural renewable materials and is the basis of Eastman CAP-482-0.5. By dividing the total amount of carbon atoms per anhydroglucose unit by the six carbon atoms derived from biomaterials per anhydroglucose unit, the estimated bio-content value of 45% for Eastman CAP-482-0.5 was calculated.
Even though the reported value is not explicitly measured for bio-carbon, it can be inferred from usual partition data. Eastman CAP-482-0.5, Food Contact, should be consulted for uses that need to be compliant with laws governing food contact.
