Ilmenite sand is primarily utilized in the creation of titanium and its dioxide form.

Titanium is a durable. lightweight metal that boasts the strongest weight-to-strength ratio among all other metals. Its dioxide counterpart finds its way into numerous items such as paints. plastics. paper. and inks to impart whiteness. opacity. and brightness.

Additionally. it serves as a coloring agent in the food sector and in sunscreens for shielding against harmful UV rays.

In addition to these uses. this sand also plays a crucial role in welding and heavy mineral blasting. Furthermore. it serves as a valuable source of metal for aerospace technology. sports equipment. and medical implants.

Polypropylene, a thermoplastic polymer used in a wide range of applications from packaging to textiles, is denoted by the recycle number 5 within the resin identification code system. This code, represented by a triangle of arrows surrounding the number 5, indicates the type of plastic for efficient recycling processes. Despite its wide usage, the recycling rate of polypropylene is not as high as some other plastics, like PET (#1) and HDPE (#2), due to varying municipal recycling capabilities and the economic considerations of recycling lower volumes. However, efforts are ongoing to improve its recyclability through advancements in sorting technology and by increasing consumer awareness of proper recycling practices. Recycling polypropylene not only conserves resources but also minimizes environmental impact, making it a crucial practice in sustainable waste management.

The MFI (Melt Flow Index) of polypropylene (PP) is a critical measure indicating the material's flowability or viscosity during the molding process. It's measured in grams per 10 minutes under specified conditions of temperature and pressure, according to standards such as ASTM D1238 or ISO 1133. Polypropylene types with a higher MFI are easier to process as they flow better, making them suitable for thin-walled products or intricate mold designs. Conversely, lower MFI PP offers better mechanical properties and is preferred for applications demanding higher strength and rigidity. The specific MFI value selected for a PP grade depends on the intended application, processing technology, and performance requirements. This makes understanding the MFI crucial for manufacturers and designers in selecting the right PP grade for their products.
