There are four categories of wave solder pallet materials. When creating a pallet, you may specify a category or a specific material. If you specify a category, the manufacturer will select a suitable material from that category.
A flux-resistant material is recommended for use when the solder flux is corrosive, containing halides or dicarboxylic acids.
A high-temperature material is recommended for use when the solder bath temperature exceeds 265°C and the bottom side pre-heat temperature exceeds 140°C.
