The price of a NIBCO 2-inch polypropylene fitting or pipe can vary based on the specific type of product (e.g., union, elbow, tee) and the retailer. As of my last update in 2023, you might expect to pay anywhere from $5 to $30 for such items, depending on the complexity and application of the piece. Polypropylene is favored for its resistance to chemical erosion and its suitability for use in both hot and cold water applications, making it a popular choice in plumbing, water supply, and chemical processing. Prices can fluctuate based on market conditions, availability, and advancements in polypropylene technology. For the most accurate and current pricing, it's best to consult directly with suppliers or check online marketplaces that specialize in plumbing supplies. Always consider the total cost, including shipping or additional fees, when purchasing online.

Cellulose powder does not contain gluten. Gluten is a protein found in wheat, barley, and rye, used for its elasticity in foods. Cellulose, on the other hand, is a polysaccharide (a type of carbohydrate) derived from the cell walls of plants. It's commonly used as a non-digestible fiber additive to improve texture or as a filler in processed foods. Since it's plant-based and not derived from gluten-containing grains, cellulose powder is considered safe for those with gluten sensitivities or celiac disease. Always check labels, however, as products containing cellulose could also include ingredients with gluten.

Determining whether epoxy or Gorilla Glue is stronger depends on the application and materials involved. Epoxy is renowned for its strong, durable bonds, especially on non-porous surfaces, making it ideal for tasks requiring high structural strength, like fixing ceramics or metal. It comes in two components that, when mixed, create a chemical reaction to form a hard, solid bond. Gorilla Glue, on the other hand, is a polyurethane adhesive that expands into material pores, creating a strong bond. It's waterproof and can adhere to a variety of surfaces, including wood, plastic, metal, ceramic, and more. For woodworking or porous materials, Gorilla Glue may be superior due to its expansion and versatility. For heavy-duty repairs or tasks requiring high tensile strength, epoxy might be the better choice. Always consider the specific requirements of your project when choosing between these adhesives.
