Application

Cellulose propionate, often abbreviated as "CP," is designed to provide distinct benefits over cellulose acetate by utilizing propionic acid in its production process. This unique composition makes it internally plasticized, requiring less additional plasticizer to maintain its toughness, unlike cellulose acetate. A key advantage of cellulose propionate is its reduced moisture absorption, which leads to greater dimensional stability. This feature makes it an ideal choice for applications requiring precision and close tolerances, especially when metal inserts are involved. Its durability and stability make cellulose propionate a popular choice for manufacturing various industrial components, including automotive parts like steering wheels, armrests, and knobs. Additionally, it is used in the production of telephones, toys, fashion accessories, women's shoe heels, pen and pencil barrels, and toothbrushes, showcasing its versatility across multiple industries.
