Cutting PVC (polyvinyl chloride) piping can be done using several tools, depending on the precision and cleanliness of the cut required. For straight, clean cuts, a PVC ratchet cutter is ideal, especially for smaller diameter pipes (up to about 1-1/2 inches). For larger pipes, a miter saw or circular saw can be used, ensuring a straight edge guide is employed for accuracy. Handsaws specifically designed for cutting plastic, such as a hacksaw, can also be used, but may require more effort to achieve a clean, straight cut. For in-place cuts or tight spaces, a cable saw, which is a wire saw designed for cutting PVC, offers a flexible solution. Regardless of the tool, measure and mark your cut line clearly, and consider deburring the cut edges with a utility knife or sandpaper to remove any roughness, ensuring a proper fit when connecting pipes.

Titanium is 60% denser than aluminum. so it is heavier.

Polypropylene, a versatile and commonly used plastic, is a polymer primarily composed of propylene monomers (C3H6). Its structure is characterized by the repeating units of propylene, which undergo polymerization to form the long chains of the material. The main chemical in polypropylene is thus propylene. However, during its manufacturing process, various additives may be incorporated to enhance its properties such as thermal resistance, flexibility, and durability. These additives can include antioxidants, UV stabilizers, colorants, and flame retardants, depending on the intended use of the final product. The specific formulation and chemical composition of polypropylene can vary, but the base chemical remains propylene.
