Cellulose Acetate (CA)

 

Cellulose acetate products have a warm feel, are sweat-resistant, and self-luminous. It is a traditional polymer with bright colors and a syrup-like transparency. Its development began in the early 20th century, even before Bakelite. Due to its marble-like effect, cellulose acetate is often used in products such as tool handles, eyeglass frames, and hair clips, making it one of the most easily recognizable polymers.

 

Using it as a material for hand tools combines its excellent compressive strength with a good feel. Other materials, such as polypropylene, have better compressive strength but feel slippery. The self-luminous quality of cellulose acetate comes from its softness; minor surface scratches can be polished away. It contains cotton and wood (cellulose) components and can be processed by injection molding, transfer molding, and extrusion. Sheet products are also available.
