First UNIPOL^® PP Technology Licensee in China to Successfully Produce Terpolymer Using CONSISTA^® C602 Catalyst System

Grace is pleased to announce the successfully produced advanced terpolymer polypropylene (PP) resins grades for heat seal packaging and rigid packaging applications. 

This success resulted from Grace’s UNIPOL^® PP technology licensee, Yunnan YunTianHua Petrochemical Co., Ltd. (YTH), using our CONSISTA^® catalyst systems. The resins were produced in YTH’s newly retrofitted UNIPOL^® PP technology plant, which can produce a full range from commodities to advanced products - including medical syringes, food storage containers, and other medical and household products.

Grace has had a presence in China since 1987 when Grace became the first wholly foreign-owned company to do business in the country. This experience has helped Grace with its knowledge of the market and the need for polypropylene resin producers to have product differentiation. Historically, specialty-grade terpolymer PP resins have been imported products, but YTH was looking to break this dependency and begin making terpolymers in-country using Grace’s UNIPOL^® PP process technology and CONSISTA^® non-phthalate polypropylene catalyst systems.

Terpolymer resins have a very low heat seal temperature with high thermal strength, which is important for both food and non-food packaging, as well as high-end medical-grade raw materials. The terpolymer PP resins that YTH manufactured exhibited excellent mechanical, optical, and processing properties with CONSISTA^® catalyst systems.

Mr. Jiang Ling, Chairman & General Manager of Yunnan YunTianHua commented, “We are so pleased to share that we had a successful initial startup of the retrofitted terpolymer plant with full capacity. I would like to express my sincere thanks to Grace for their support, hard work and professional guidance at our site. The past two years were very tough for YTH with the pandemic and unexpected difficulties. However, nothing could stop us moving forward as we figured out measures and overcame all the difficulties. We are very proud to be the first UNIPOL^® PP technology licensee in China with retrofitted terpolymer capability. This is a testament to Grace’s strong R&D capability and partnership, which enhances our confidence for future cooperation.”
