How does the resistance to mold of polypropylene compare to polyethylene in outdoor tables?

When choosing materials for outdoor tables, mold resistance is a critical factor to consider. Polypropylene and polyethylene are two popular plastics used in outdoor furniture, but how do they compare in terms of mold resistance?

Polypropylene is known for its excellent resistance to mold and mildew. Its hydrophobic nature means it does not absorb moisture, making it less likely to foster mold growth. This makes polypropylene a preferred choice for outdoor tables in humid or wet environments.

On the other hand, polyethylene also offers good resistance to mold, but it is slightly more porous than polypropylene. While it is still a durable option for outdoor furniture, it may require more maintenance to prevent mold buildup over time, especially in damp conditions.

In summary, polypropylene generally outperforms polyethylene in mold resistance for outdoor tables due to its non-absorbent properties. However, both materials are viable options, and the final choice may depend on other factors such as cost, design, and specific environmental conditions.
