Plastic beads are made out of plastic. Sometimes they are coloured to add an appealing effect.
The boiling point of PVC plastic is approximately 140-160°C (284-320°F). At this temperature, PVC will soften and start to decompose. It is important to note that PVC should not be heated above its boiling point as it can release toxic fumes.
bringing water to boil is effective in killing or inactivating most bacteria viruses and pathogens .according to the wilderness medical society water temperatures above 160 degree kill all pathogens

Put them in water.
For feathers, foam plastic, cotton ... all well above the boiling point for water.
Both plastic and wood float's on water. My guess is that the wood is from the pellets.
Melting plastic beads with an iron can release harmful fumes and should be avoided. It is not safe to melt plastic beads with an iron as it can create toxic gases and pose a fire hazard. It is recommended to use a proper melting tool or oven designed for melting plastic beads to ensure safety.
Boiling is the phase where the boiling occurs. The point at which the boiling occurs is the boiling point.

"Plastic" is a generic name for many different substances, which basically have two things in common: they are made artificially, and they are polymers. Therefore, properties such as the boiling point can be expected to vary widely. You can look up the properties by searching (for example) the Wikipedia, for individual types of plastic, such as as "PVC", "polyurethane", etc.
