BRIEF OVERVIEW

Polypropylene is a thermoplastic that belongs to the polyolefin group of materials. Like most polyolefins, polypropylene is approved for direct food contact. Polypropylene Homopolymer is the most widely utilized general-purpose grade. It contains only propylene monomer in a semi-crystalline solid form. Polypropylene homopolymer is the most utilized polypropylene. PPH is more rigid and stronger than the copolymer. It can run in the temperature range 30º to 180º F. It has good weldibility, has high performance in thermoforming, has good chemical resistance, and is also USDA, FDA, NSF, and 3-A Dairy compliant.

 

MANUFACTURING PROCESS

A process for Polypropylene homopolymer, wherein propylene is polymerized in the presence of a catalyst at an elevated temperature in a reaction medium in which a major part of the reaction medium is propylene and the polymerization is carried in at least one CSTR or loop reactor, where the polymerization is carried out at a temperature and a pressure which are above the corresponding critical temperature and the pressure of the reaction medium and where the residence time is at least 15 minutes. The process can also comprise a supercritical loop polymerization before the supercritical stage polymerization or a gas phase polymerization after the supercritical stage polymerization.
 

Packaging Applications

Good barrier properties, high strength, good surface finish and low cost make Polypropylene Homopolymer ideal for several packaging applications.

 

Consumer Goods

Polypropylene Homopolymer is used in several household products and consumer goods applications including translucent parts, housewares, furniture, appliances, luggage, toys etc.

 

Automotive Applications

Due to its low cost, outstanding mechanical properties and moldability, Polypropylene Homopolymer is widely used in automotive parts. Main applications include battery cases and trays, bumpers, fender liners, interior trim, instrumental panels and door trims.
