Nantong Xingchen Synthetic Materials Co., Ltd. (NTXC), the largest engineering
plastics production and R&D site owned by China National Bluestar Group, has
introduced a filament grade PBT (Polybutylene Terephthalate) resin with the
grade of Starester®1100A FL. It is mainly applied to tooth brush filaments
and cosmetic filaments.

With the unique and innovative polymerization technology to precisely
controlling the crystallization and rheology behavior of PBT polyester
materials, Starester®1100A FL exhibits excellent elasticity and high
transparency after melt spinning, and this innovative technology of production
process controlling by means of RTDB contributes to the excellent stability in
product’s quality.

Compared with traditional polyamide (nylon6,12) materials used in the filament
area, Starester®PBT have more superior physical properties such as elasticity
and softness after being applied to the filament field, moreover, PBT filament
can be tapered to about 18μm diameter, which creating best tactile experience
for people during teeth brushing. It has been applied to the filament products
by many well-known global and several toothbrushes brands, further enriching
the product line of Starester®.
