Is the trolley case pp good? Or other materials?
The PP material is polypropylene and the PC material is polycarbonate. First of all, in theory, both are non-toxic, but in terms of aging resistance and weather resistance, PP is more suitable for fresh-keeping boxes.
PC is generally synthesized by the bisphenol A type method, and contains benzene rings in the molecule. Although PC itself has good heat resistance, as a polymer material, it still contains some low molecular substances inside. These substances are exposed to heat and light. Under high pressure, it will volatilize and decompose, and most of them are carcinogenic. There will be more or less the existence of bisphenol A monomer in food utensils made of PC. The higher the temperature, the more the release and the faster the speed.
In addition, the toughness of the pp material is good, and the trolley case made of it will not be broken or broken! The box car of the pp trolley case will not crack when rolled over! The pp material is safe and stable, high temperature will not have peculiar smell, environmental protection and non-toxic! Low temperature will not become hard and brittle! These are all things that trolley cases made of pc and abs do not have!
The best material for making a trolley caseis pp material, but the production cost of pp made into a trolley case is high and the process is complicated, so generally small workshops and small processing plants do not have the strength to produce, and the high price also makes the proportion of pp trolley cases on the market small, naturally There are not many people who know about pp trolley cases, so if you don't understand it, you shouldn't talk nonsense. . . As for the pc and abs pull boxes that occupy 96% of the market, you can buy some box shells, wheels, and pull rods in a small workshop, and you can assemble them at home with a few simple tools. Naturally, the price is low. There are more people. . . . The PP trolley case
is made of injection molding process, only the regular big factory has the strength and equipment to produce the pp material trolley case. . . . .
So as a professional, the trolley case made of pp material is the best! !
