Phenolic is short for Phenol Formaldehyde Resin (PF). At 220°C (428°F) or above, Phenolic caps will start to decompose. However, due to their non-chemically reactive nature, when exposed to corrosive or harmful chemicals over time, phenolic caps will not give out the way other polymers might. They're very tough when used in the correct temperature range.*
