Colored Polymer PP Polypropylene Sheet Alkalis Resistance Customized

Polypropylene (PP) sheets are essential for modern laboratories due to their exceptional chemical stability, durability, and safety. These characteristics make them ideal for lab environments exposed to corrosive reagents, frequent sterilization, and strict contamination control requirements.

As a thermoplastic polymer with a linear molecular structure, PP sheets offer distinct chemical advantages:

• Excellent resistance to most common lab reagents including acids (hydrochloric acid, sulfuric acid up to 70% concentration, acetic acid) and bases (sodium hydroxide, potassium hydroxide up to 50% concentration) at room temperature
• Impervious to non-polar solvents (mineral oil, gasoline, toluene) and many polar solvents (ethanol, methanol) at low to moderate temperatures
• Stable molecular bonds prevent the release of additives or polymer fragments, maintaining sample purity
• Superior to metal (which rusts) or glass (which can be etched by hydrofluoric acid)

• High thermal stability (-20°C to 120°C) for sterilization needs
• Lower coefficient of thermal expansion than polyethylene for dimensional stability
• Biological inertness - non-toxic to cell cultures and microorganisms
• Non-porous surface prevents microbial growth
• Resists atmospheric oxidation and UV degradation
• Maintains properties during autoclaving without warping or breakdown

PP sheets are versatile for various laboratory applications:

• Lab workbenches: Protective liners against spilled reagents with easy cleaning
• Chemical storage: Cabinets, drip trays, and secondary containment bins
• Fume hoods: Liners and ductwork resistant to corrosive fumes
• Life science equipment: Cell culture tray lids, homogenizer chambers, microplate racks
