Tenite™ Butyrate 285A2R30020 Natural, Trsp
醋酸丁酸纤维素
Eastman Chemical Company
产品说明:
Tenite™ cellulosic plastics are noted for their excellent balance of properties - toughness, hardness
, strength, surface gloss, clarity, and a warm feel. The mechanical properties of Tenite™ cellulosic pl
astics differ with plasticizer levels. Lower plasticizer content yields a harder surface, higher heat resi
stance, greater rigidity, higher tensile strength, and better dimensional stability. Higher plasticizer c
ontent increases impact strength. Tenite™ cellulose plastics are available in natural, clear, selected
ambers, or smoke transparents and black translucents. Color concentrates are available in let-dow
n ratios from 10:1 to 40:1. Tenite™ Cellulose Acetate Butyrate 285-20 has a plasticizer level of 20%
and contains an odor mask.
