Revision as of 02:59, 23 June 2005 by 202.49.141.2 (talk) (Added notes on starch and bioddegradability.)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)Polycaprolactone (PCL) is a biodegradable polyester with a low melting point of around 60°C. It must be raised to melting point to biodegrade, and so must be composted. it is often mixed with starch to lower the cost and increase biodegradability.
It is used for splinting, modelling, and as a feedstock for prototype Fused Deposition Modeling systems such as RepRap.
As it is sourced from fossil carbon, the usefulness of biodegrading PCL is dubious since this will increase the amount of fossil carbon added to the atmosphere.
