Isotactic polypropylene is a resin material used in the production of pharmaceutical packaging, etc. It is also called isotactic polypropylene. It is a type of polypropylene, and the methyl group in the molecule is on one side of the main chain. According to the arrangement of the methyl group, it is divided into three types: isotactic polypropylene, random polypropylene and syndiotactic polypropylene. In the general industrial production of polypropylene resin, the isotactic structure content is about 95%, and the rest is random or syndiotactic polypropylene. Industrial products are mainly composed of isotactic substances.
A type of polypropylene (the other two are syndiotactic polypropylene SPP and random polypropylene APP). Polypropylene is a thermoplastic resin made by propylene polymerization. According to the arrangement of the methyl group, it is divided into three types: isotactic polypropylene, random polypropylene and syndiotactic polypropylene. The methyl group (-CH3) in the molecular chain is distributed on one side of the main chain, so it is called isotactic polypropylene.
In the general industrial production of polypropylene resin, the isotactic structure content is about 95%, and the rest is random or syndiotactic polypropylene. Industrial products are mainly composed of isotactic substances.
