PP material can safely hold boiling water. This material possesses excellent heat resistance, and products made from it can undergo sterilization and disinfection at temperatures exceeding 100°C.
In the absence of external forces, PP material will not deform at temperatures of up to 150°C. Its embrittlement temperature is approximately -35°C; temperatures below this threshold may cause the material to become brittle, indicating that its cold resistance is inferior to that of polyethylene. The melting point of PP typically falls between 164°C and 170°C, while that of isotactic PP can reach as high as 176°C. Consequently, using containers made of PP material to hold boiling water poses no issues.
When using PP plastic containers for boiling water-given that the processing temperatures during manufacturing typically range from 180°C to 240°C-boiling water will not cause the material to decompose, and its chemical properties remain relatively stable. Nevertheless, for daily hydration-particularly when consuming boiling water-it is recommended to opt for stainless steel insulated mugs, glass cups, or ceramic cups, as these materials are more conducive to healthy drinking habits.
