What plastics can withstand boiling water?
HDPE or High Density Poly Ethelene plastic has an amazing temperature range, and is considered safe for short periods up to 248°F (120°C) or for long periods up to 230°F (110°C.) Since boiling water never gets above 100°C, this means that anything boiling and below is safe for a food grade bucket.
