PP boards excel in chemical performance. They boast strong resistance to acids, alkalis, and organic solvents, remaining stable without dissolving or releasing toxins when in long-term high temperature. Therefore, they could be used for kitchen equipment.
Excellent Performance
Fire-proof PP boards for lab countertops deliver excellent performance. They have Class B1 or higher fire resistance, resisting flames without toxic fumes during combustion. This stops fire spread from alcohol/chemical leaks in experiments, meeting lab fire safety standards. They also offer strong chemical resistance, withstanding strong acids (e.g., sulfuric, hydrochloric acid), alkalis (e.g., sodium hydroxide), and organic solvents without dissolution, discoloration, or surface damage—avoiding countertop contamination that harms experimental accuracy.
High-temperature Stability
With high-temperature stability, they work continuously at 100-120℃ (150℃ short-term), letting heated glassware sit directly on them; they stay unsoftened and flat long-term, fitting lab heating scenarios. Their dense, non-porous surface is antibacterial and easy to clean: no bacteria/mold growth, and reagent residues or sample marks wipe off quickly with water or detergents, cutting deep cleaning needs and cross-contamination risks. Plus, they have excellent electrical insulation (volume resistivity ≥10¹⁴Ω·cm), insulating current between countertops and equipment to prevent malfunctions or electric shocks, suitable for electronic experiments.
Cost Advantage
In terms of cost, fire-proof PP boards outperform traditional materials (epoxy resin, stainless steel): Raw material costs are 20%-40% lower, with simple processing (no complex surface treatment) reducing finished countertop prices. Maintenance/replacement costs are low too—their corrosion/wear resistance means no special daily care; slight wear fixes via simple grinding (no full replacement), with annual maintenance per countertop at 1/3 that of epoxy resin boards. Lightweight (≈0.9g/cm³, 50% lighter than stainless steel), they need no heavy equipment for installation, cutting labor costs by 30%, and flexible cutting reduces material waste to control costs further.
