Polypropylene (PP) is a thermoplastic polymer known for its versatile properties, making it widely used in various applications. It boasts a high resistance to chemicals, water, and electricity, making it ideal for containers and medical equipment. Polypropylene has a low density, leading to lightweight products, yet exhibits high tensile strength, providing durability and resistance to physical impacts. Its melting point is relatively high (around 160°C), allowing for thermal resistance in applications requiring sterilization. Additionally, PP is recyclable, aligning with sustainable manufacturing practices. However, its susceptibility to UV degradation can be mitigated through additives. Overall, PP's balance of properties—cost-effectiveness, durability, and chemical resistance—accounts for its broad utility in packaging, automotive parts, textiles, and consumer goods.

Density Polyethylene Foam, commonly known as PE foam, is a durable, lightweight foam with a closed-cell structure. It's manufactured through the polymerization of ethylene, yielding a material that's highly versatile, water-resistant, and thermally insulating. This foam finds widespread use in packaging, automotive, sports equipment, and construction, thanks to its excellent shock-absorption properties and resistance to chemicals. Available in various densities, it allows for customization to specific application needs, from soft and pliable for cushioning to firm for structural support. Additionally, its compatibility with a wide range of fabrication processes, including cutting, molding, and thermoforming, makes it a preferred choice for many industries.

Strikethrough in ZipForm Digital Ink is not a directly supported feature on all platforms. To achieve a strikethrough effect, users often have to be creative. One method is using the annotation tools, specifically the line or drawing tool, to manually draw a line through the text you want to strike out. This method, while not perfect, allows you to visually indicate text modifications or deletions. Another workaround could be typing out your text in another program that supports strikethrough, such as Word, then screenshotting it and adding it as an image in ZipForm Digital Ink. Remember, the key to using workarounds effectively is ensuring clarity and maintaining professionalism in your documents.
