PP Properties

Full Name Polypropylene
Max Temperature 100°C (212°F)
Min Temperature 0°C (32°F)
Density 0.90 g/cm³

Common Applications

Chemical Tanks

Acid and alkali storage tanks and vessels

Lab Equipment

Bottles, funnels, trays, autoclaving containers

Piping

Chemical-resistant piping and fittings

Not Recommended For

PP may degrade when exposed to:

  • Strong oxidizers
  • Chlorinated solvents
  • Aromatic hydrocarbons
  • Concentrated nitric acid

Tip: PP becomes brittle below 0°C. For cold environments, use HDPE or LDPE.
