Eastman Tenite Butyrate 485A2R30016-Natural Cellulose Acetate – Frequently Asked Questions (FAQ)

Q1: What is the primary functional role of Eastman Tenite Butyrate 485A2R30016 in polymer formulations?

A: It functions primarily as a biobased plasticizer and processing aid for cellulose esters and select thermoplastics, enhancing melt flow, reducing melt viscosity, and improving impact resistance and surface gloss without significantly compromising thermal stability.

Q2: Is this grade suitable for applications requiring FDA compliance for indirect food contact?

A: Eastman Tenite Butyrate 485A2R30016 is manufactured to meet Eastman’s internal specifications for purity and consistency in food-contact applications. Customers must validate final formulation compliance per applicable regulatory requirements, including FDA 21 CFR §175.300 and §177.1010, based on end-use conditions and migration testing.

Q3: How does this butyrate grade compare to standard cellulose acetate in terms of moisture sensitivity and dimensional stability?

A: Compared to conventional cellulose acetate, Tenite Butyrate 485A2R30016 exhibits lower hygroscopicity and improved dimensional stability under variable humidity, making it better suited for precision-molded parts and thin-gauge extrusions where moisture-induced warpage or shrinkage is a concern.

Q4: Can it be used in combination with other plasticizers or polymer modifiers?

A: Yes — it is commonly blended with other compatible plasticizers (e.g., triethyl citrate or acetyl tributyl citrate) to fine-tune flexibility, processing window, and final mechanical performance. Compatibility should be confirmed via small-scale trials due to potential interactions affecting clarity or phase separation.
