Plastic NPP board, there is no poison?
PP engineering plastics are called polypropylene. It is a fine kind of resin developed after nylon. It is a kind of linear polymer with high density, no side chain and high crystallinity. It has excellent comprehensive properties. PP has good solvent resistance, oil resistance, weak acid resistance, weak alkali and other properties. POM has a high hardness and steel, has a high degree of creep and stress relaxation ability, excellent wear resistance, self-lubricating, and fatigue, and other engineering plastics can not be compared.
PP plastic in engineering also has many applications, such as electroplating trough used PVC plastic, now because of PP has better performance, manufacturing integrated cost and PVC similar, have mostly use PP plastic manufacturing. Most of the household tap water pipes are replaced by PP tubes, which is clean, sanitary and easy to install.
If it is made of polypropylene, the cup is non-toxic and the processing temperature (DEG) is 180~240. So boiling water doesn't break it down.
