It is better to be careful rather than sorry when you are out on an adventure. Fiberboards with tops made of aluminium can technically withstand the heat of a camping stove. However, it is better to invest in a mat to put under the stove. An even better choice is to use a camping stove with a burner shield base attached to them. This shield will provide an extra layer of protection for your table or anything you might be using. In conclusion, it is always better not to put a regular camping stove directly on top of your plastic table without any protection.
