There is a density of 4.506 g/cc in 20C Titanium. The weight depends on the size and type of titanium used.

Polypropylene is considered a good insulator for both electrical and thermal purposes. Its molecular structure provides low thermal conductivity, making it efficient in minimizing heat transfer. In the electrical context, polypropylene exhibits high resistivity, preventing the flow of electric current and making it an ideal choice for insulation in electrical components and systems. Additionally, its moisture resistance enhances its insulating properties by preventing water absorption, which can lead to a decrease in insulating capability. Polypropylene's lightweight, durability, and chemical resistance further contribute to its effectiveness as an insulator in various applications, including packaging, automotive, and construction. However, the insulating effectiveness of polypropylene can be influenced by factors such as thickness and environmental conditions.

Yes, PVC can crack in cold weather due to its decreased flexibility in lower temperatures. PVC (Polyvinyl Chloride) is a widely used plastic that becomes less pliable and more brittle as the temperature drops, making it more susceptible to cracking under impact or stress. This vulnerability is especially pronounced in regions with severe cold spells. As a preventative measure, it’s advisable to use PVC materials rated for cold temperatures or to consider alternatives like ABS (Acrylonitrile Butadiene Styrene) which maintain better toughness in cold climates. Regular inspections for damage and proper installation according to manufacturer guidelines can also mitigate risk.
