How much is plastic PP5 resistant to cold?
Ordinary homopolymer PP has higher heat resistance, but when it reaches -20 degrees of low temperature, it will not stand, easy to brittle.
It can be used for a long time at 100~120 DEG C and no problem with boiling water
Copolymerization of PP is generally more common than ordinary poly PP, low temperature, usually twice as much, that is, -20 degrees.
The number 5 stands for PP plastic, or polypropylene plastic, non-toxic, tasteless and odorless, with a melting point of around 170
