Material from extortionist's family (9)

I believe the answer is:

sharkskin

'material' is the definition.
(I know that sharkskin is a type of material)

'extortionist's family' is the wordplay.
'extortionist's' becomes 'shark's' (as in a loan shark).
'family' becomes 'kin' (synonyms).
'sharks'+'kin'='SHARKSKIN'

'from' acts as a link.

(Another definition for sharkskin that I've seen is " material".)

I've seen this clue in The Guardian.
