Effect of Polysulfide and polyurathane on plastic ports

Thanks for your response.
Yeah, we''re pretty smart here I guess and I''m well aquainted with the different types of sealant/adhesives and their applications but that wasn''t the question.
The reason I asked the question is last week I removed a port in a boat that was installed 27 years ago. It hasn''t leaked in 27 years and it was bedded in with 5200 and the port is still in perfect shape.
If both polys are supposed to attack plastic ports, why did this beddidg job last so long and why is the port(and the rest of the ports that still aren''t leaking)still in perfect shape?
