ABSTRACT OF THE DISCLOSURE A thermoplastic composition, especially for use as an orthopaedic splinting or casting material comprises a crosslinked polymeric component and a filler. The crosslinked polymeric component comprises a polycaprolactone, such as poly(epsilon)- caprolactone, and a thermoplastic rubber in a ratio of from about 4:1 to about 1.5:1 by weight. Styrene-butadiene-styrene and styrene-isoprene- styrene triblock copolymers are particularly suitable thermoplastic rubbers. Crosslinking may be carried out using an organic peroxide such as benzoyl perox- ide. The filler is preferably a mixture of talc and silica.
