"WINTEC™" is a completely new PP with a homogeneous molecular structure and a variety of performance features that conventional catalysts cannot achieve.
The original metallocene catalyst technology developed by Japan Polypropylene Corporation makes it possible to create the PP polymer molecular structure as intended.

Molecular weight (length) and crystallinity are consistent, with low molecular weight and low crystallinity components.
Metallocene PP WINTEC™ is characterized by its slim molecular structure, which significantly reduces unnecessary low molecular weight and low crystallinity components by narrowing the crystallinity (regularity) and molecular weight distribution.
This results in a clean material with little smoke generation, roll staining, product stickiness, or odor during molding. It also has excellent solvent extraction resistance, making it suitable for food packaging and medical applications.
In addition, for random PP (ethylene-propylene random copolymer), we have succeeded in developing PP with an ultra-low melting point, which could not be achieved with conventional catalysts. This PP offers unprecedented and outstanding performance in applications such as heat-sealing films.
