The shelf life of inkjet cartridges typically ranges from 18 to 24 months from the manufacture date if they remain unopened and are stored correctly in a cool, dry place. Once you open an ink cartridge, it's best to use it within 6 months to achieve optimal performance, as ink can dry out or degrade, affecting print quality. Factors such as cartridge design, manufacturer, and storage conditions can influence the exact shelf life. To extend the lifespan of your inkjet cartridges, it’s advisable to follow the manufacturer's storage guidelines and avoid exposing cartridges to extreme temperatures or direct sunlight. It's also a good practice to print regularly to prevent ink from drying out in the nozzles of the printer head.

Polymers are large molecules formed from smaller units called monomers through a process called polymerization. Two main types of polymerization reactions are addition (chain-growth) polymerization and condensation (step-growth) polymerization. In addition polymerization, monomers add to each other without the loss of atoms from the monomers. For instance, the polymerization of ethylene into polyethylene involves opening the double bond in ethylene molecules to form long chains. In contrast, condensation polymerization involves the covalent bonding of monomers along with the small molecule's elimination, such as water or methanol. An example is the formation of nylon from diamine and dicarboxylic acid, producing water as a by-product. These reactions are essential in creating various synthetic materials with a wide range of applications, including packaging, textiles, and automotive parts.
The question "which is better, plastic or polypropylene?" necessitates clarification since polypropylene (PP) is actually a type of plastic, specifically a thermoplastic polymer used extensively in a variety of applications. Comparing polypropylene to other plastics involves considering factors such as durability, chemical resistance, recyclability, and application-specific requirements. PP is renowned for its excellent chemical resistance, making it suitable for containers of liquids, including acids and bases. It also has a high melting point, which makes it ideal for items that need to withstand heat. Polypropylene is also recyclable, which is a significant environmental benefit. However, some plastics, like polyethylene (PE), might be chosen over PP for their flexibility and lower cost for specific applications. Thus, the "better" material depends on the specific requirements of the application, including factors like strength, durability, chemical resistance, and environmental impact.
