Polyvinyl chloride (PVC) can indeed be recycled, but it presents unique challenges compared to other plastics. PVC recycling involves sorting it from other plastics due to its chlorine content, which can release harmful chemicals if not properly processed. Specialized recycling facilities use mechanical recycling, transforming it into granules for use in new products, or chemical recycling, breaking it down to its basic molecules. However, the complexity and cost of recycling PVC often limit its recyclability, leading to a focus on reducing its use and finding alternatives. Recycling facilities capable of processing PVC are less widespread, so it's vital to check local recycling capabilities.
Epoxy may not harden correctly for a few reasons: incorrect mix ratio of resin to hardener, insufficient mixing, using expired components, or temperature issues (too cold). It's crucial to follow the manufacturer's instructions precisely. Ensure the mix ratio is correct and thoroughly mixed. Old or poor-quality materials can also fail to cure. Check the product's shelf life and store it in a suitable environment. If the working area is too cold, consider heating it up to meet the epoxy's recommended curing temperature. Sometimes additives or fillers, if not compatible, can interfere with curing. Reviewing these factors can pinpoint the cause and help avoid future issues.
Polypropylene (PP) is a thermoplastic polymer that is considered combustible. It has a relatively high ignition temperature around 570°F (300°C) but once ignited, it can burn readily. Being a hydrocarbon, PP's combustion releases water vapor and carbon dioxide, along with potential hazardous gases if burning is incomplete. Moreover, PP melts at a temperature of approximately 320°F (160°C), which means in fire conditions it can flow, spreading the fire. Its behavior in fire situations is influenced by the presence of flame retardants which can improve its resistance to ignition and slow down the burning process. However, without such additives, polypropylene must be treated with caution around open flames or high heat sources.
