Table 1 shows some properties of a polymer and wood.
| Property | Polymer | Wood |
|---|---|---|
| Flexibility | medium | low |
| Hardness | medium | medium |
| Reaction with rainwater | no reaction | decays slowly |
| Density | low | medium |
The polymer, rather than wood, is a more suitable material for outdoor fence posts.
Give one reason for this, using a property from Table 1.
