Unplasticized Polyvinyl Chloride (uPVC) is renowned for its excellent resistance to a wide array of chemicals, including acids, alkalis, alcohols, and some oils. Its highly rigid structure, due to the lack of softening agents (plasticizers), contributes to its superior chemical resistance compared to its plasticized counterpart. However, it does have vulnerabilities; solvents and ketones can cause damage or degradation. This robust resistance makes uPVC an ideal material for pipes and fittings in construction, offering long-lasting performance in various chemical environments. Careful selection based on the specific chemical exposure is recommended to ensure the longevity and integrity of uPVC installations.

To make a deer feeder from PVC pipe, start with a large diameter PVC pipe (4-6 inches wide) for the body. Cap one end securely and cut a small feeding hole or several small holes near the bottom on the uncapped side. Attach a Y-shaped PVC connector at the capped end if you want to spread feed further. Mount the pipe vertically or at a slight angle to ensure gravity helps feed move towards the holes. Fill with deer feed from the top, capping it to keep moisture out. Mount the feeder on a stable post or tree at a height accessible to deer but not to smaller animals if possible. Regularly check and refill as needed to keep the deer returning.

Polyvinyl chloride, commonly known as PVC, is a versatile synthetic plastic polymer used extensively in various industries. Its key applications include construction, where it serves as material for pipes, windows, and doors, due to its strength, durability, and resistance to moisture, chemicals, and weathering. In healthcare, PVC is used for disposable items like IV bags, tubing, and containers, thanks to its non-reactivity and safety. Additionally, PVC finds use in the automotive sector for vehicle interiors and electrical cable insulation, and in everyday products, such as clothing, footwear, and packaging, due to its flexibility when plasticized. Its widespread utility stems from its cost-effectiveness, easy processing, and recyclability, although concerns about environmental impact and health issues related to certain additives like phthalates are prompting research into more sustainable alternatives.
