Polypropylene vs Polystyrene. Everyone is making polycarbonate sound like it is the strongest and best material. As many have noted, it is not the material alone that will make a chair perform better or worse. It is difficult to see from only a picture but if you were to examine each one of these suitcases in real life, the differences would be immediately apparent. It has been extensively compounded to provide a wide range of properties at a wide range of costs. This type of sheet is ideal for use in construction, architecture, roofing, and glazing applications because it can be shaped, cut, … See for yourself on my what luggage do I own page. Because of these properties, polycarbonates find many applications. They can get away with it because the advertised cases are made with polycarbonate shells which do contain carbon - we know, it's a bit of a stretch so be forewarned. amzn_assoc_asins = "B004HKSENY"; amzn_assoc_ad_type = "smart"; polypropylene suitcase is the lightest available on the market. This combination of metals results in some impressive benefits: When an aluminum suitcase is brand new, they look very impressive and futuristic. Polypropylene vs Nylon . Simply apply a little methylene chloride to the inside wall of the case and then some on the Lexan sheet. So they have engineered a blend of part polycarbonate and part ABS (Acrylonitrile Butadiene Styrene) plastic that results in a much stronger material without sacrificing to much added weight. Aluminium-magnesium alloy hard shell luggage tends to be the reserve of the top luxury luggage lines but in the past few years, several Chinese companies have entered the market with much cheaper (read inexpensive not poorly made) look-a-like aluminum hard shell suitcases. It is produced via chain-growth polymerization from the monomer propylene. ABS is only used in the lowest cost hard side luggage so when comparing it to polypropylene there is no competition. We have written an article that explores the differences between hard sided and soft sided luggage to back up our opinion. amzn_assoc_ad_mode = "manual"; Like the other plastic materials, ABS is used to create suitcase shells in a process called injection molding. A Brief History of ABS: Polycarbonate is naturally white or clear but it can be color-dyed and even transfer printed on. Just about everyone probably has something made of propylene in their households. This makes it resistant to rough handling. Do you want a light case whos weight will allow you to pack more into it or do you want a really robust case that will protect your belongings? These can often be buffed-out or polished out. The differences start to appear when you look at tensile strength and impact resistance. All things considered, polypropylene is the most durable material for hard shell luggage.
