Super-bright (SBC) Polyester Chips

It does not contain TiO2, and the appearance standard is colorless and transparent particles.

The content of titanium dioxide in the Super-bright polyester chips is 0%, and the content of titanium dioxide in the Semi-dull polyester chips is 0. 30% ± 0 . 05%. In the Full dull polyester chips is up to 2 . 5% ±0 . 1%。The main difference between Semi-dull polyester chips and Full dull polyester chips is the different titanium dioxide content, which is more than 8 times that of the former. Full dull polyester chips are high value-added products. It can not only reduce the reflection and flickering phenomenon of fibers, but also make the subsequent fibers have the advantages of soft luster, good deep dyeing, high fabric drape, strong masking performance, etc., which can meet the needs of high-end clothing.

Product Introduction

Super-bright polyester chips are suitable for making the terylene filament, industrious filament,terylene staple fiber, PET film, injection mould and the other packing materials etc.

The brand of product is a special kind of super-bright chip with good color values, excellent diaphaneity, less impurity and constant viscosity. For applying the unique process recipe and production technology, the chips possess excellent processing property, high rate of the finish product, less broken fiber and less rate of blown film. So the chips are especially used to produce the lustrous fine denier filament and high-speed polyester film.
