To screw into PVC (Polyvinyl Chloride), first select a screw that is appropriate for the thickness of the PVC to avoid cracking. Use screws designed specifically for plastic, which have a wider thread pitch and are less likely to cause damage. Before screwing in, it's important to drill a pilot hole slightly smaller than the screw diameter. This helps prevent the PVC from splitting. Ensure you're using a drill bit designed for plastic to make a clean hole. When screwing in, do so gently and avoid overtightening, as this can also crack the PVC. Using a hand screwdriver can offer more control compared to a power drill.
Polypropylene is a type of plastic that is widely recognized as vegan. It is synthesized from propylene monomers, which are derived from petroleum, a fossil fuel. Unlike materials such as leather or wool, which directly involve animals in their production, polypropylene is purely a chemical product. There is no animal involvement in its manufacturing process, making it suitable for those following a vegan lifestyle. However, it's important to consider the broader environmental implications of using plastics, which can indirectly impact animal habitats and ecosystems. As a vegan, considering sustainable and eco-friendly alternatives where possible is also valuable. Nonetheless, from a strict definition of avoiding animal products, polypropylene is considered vegan.
