Blue polypropylene (PP) pipe is indeed commonly used for main water lines into houses, especially in systems designed for potable (drinkable) water distribution. This is because polypropylene pipes are known for their durability, resistance to chemical leaching, and ability to withstand high temperatures compared to other types of plastic piping. They are also less likely to corrode over time, which is particularly important for maintaining the quality of the water supply. Additionally, the blue color coding of these pipes is typically used to differentiate them from other types of pipes used in construction, such as those for gas (often yellow) or recycled water (often purple), making identification and maintenance easier for plumbers and homeowners. However, suitability and code compliance can vary by region, so it's recommended to consult local building codes and guidelines when selecting materials for water supply lines.

Adding metal additives to polymers increases their conductivity due to the intrinsic electrical properties of metals. Metals have free electrons that can move easily throughout their structure, facilitating the flow of electrical current. When metal particles are incorporated into a polymer matrix, they create a network of conductive paths. This essentially turns the insulating nature of the polymer into a more conductive composite material. The effectiveness of this process depends on the concentration and distribution of metal particles within the polymer. If the particles are well-dispersed and reach a certain threshold (percolation threshold), they form a continuous path for electron flow, significantly enhancing the material's conductivity. This method is widely used in creating conductive plastics for various applications, such as in electronics, antistatic materials, and electromagnetic shielding.
