Polypropylene (PP) is a lightweight, thermoplastic polymer highly valued for its versatility in applications ranging from plastic packaging to automotive parts. Key physical properties include its resistance to chemicals, water, and electricity, making it an excellent insulator. PP has a melting point around 160°C, which allows for easy thermal processing and recycling. Its density is approximately 0.905 g/cm^3, making it one of the lighter plastics available. Additionally, polypropylene boasts significant toughness and flexibility, even at lower temperatures, which contributes to its durability in various uses. However, it does have limitations in UV resistance and can degrade if not properly treated or stabilized for outdoor use. Enhancements through copolymerization or additives can improve its mechanical properties and expand its application range.
Synthetic resin rubber refers to a variety of synthetic materials that exhibit rubber-like properties and are created through polymerization processes, involving the combination of small molecular units into long chains. Unlike natural rubber, derived from the latex of rubber trees, synthetic resin rubbers are synthesized from petrochemicals, offering enhanced attributes such as improved temperature and chemical resistance, varying degrees of elasticity, and tailored mechanical properties to suit specific applications. Common types include styrene-butadiene rubber (SBR), nitrile rubber (NBR), and neoprene, each possessing unique features for use in automotive tires, seals, gaskets, and insulation materials. The development of synthetic resin rubbers marked a significant advancement in materials science, providing versatility and reliability across a range of industrial and consumer applications.
Lithium polymer (LiPo) batteries are commonly used in portable electronics, drones, and RC devices. For air travel, passengers can carry LiPo batteries in their carry-on luggage but not in checked bags. The International Air Transport Association (IATA) guidelines specify that personal devices containing lithium batteries (up to 100 watt-hours) can be carried without approval. Spare batteries, including LiPo, must be protected from short circuits and carried in carry-on luggage. Batteries with more than 100 but less than 160 watt-hours require airline approval. Strictly, no lithium batteries over 160 watt-hours are allowed on passenger aircraft. These regulations aim to prevent fire risks associated with lithium batteries. Always check with your airline for specific restrictions as they may have stricter rules.
