Other Characteristics of PP:
PP is a polymer prepared catalytically from propylene with an isostatic replacement of a hydrogen atom by a methyl group on alternate carbon atoms in the main chain. The material surface of PP (Polypropylene) is soft, almost wax-like and tends to scratch easily. PP Shares many of the same characteristics as HDPE though PP is a stiffer material with a higher melting point. PP is manufactured in the same ways as all other thermal plastics. The presence of the methyl group makes PP slightly more susceptible to attacks by oxidizing agents than HDPE.
Chemical Resistance:
| Acids – Dilute | Excellent |
| Acids – Concentrated | Excellent |
| Alcohols | Excellent |
| Aldehydes | Good |
| Bases | Good |
| Esters | Good |
| Ethers | Low |
| Hydrocarbons, Aliphatic | Good |
| Hydrocarbons, Aromatics | Limited |
| Hydrocarbons, Halogenated | Limited |
| Ketones | Good |
| Oils, Minerals | Good |
| Oil, Vegetable | Good |
PP for Laboratories:
PP is a good choice for product packaging because it is a highly durable material in both container and closure forms, and is a good barrier against moisture, oil, and alcohol. PP is resistant to many chemicals. PP can be sterilized by autoclaving, gas and chemical disinfectant.
Other uses of PP:
PP is often used to produce many products including ketchup bottles, yogurt containers, medicine bottles, and syrup bottles.
