Blends of Thermoplastic Polyurethane and Polydimethylsiloxane Rubber: Assessment of Biocompatibility and Suture Holding Strength of Membranes

Table 1

Suture holding strength measurement results for TPU : PDMS blends in the ratio 80 : 20 with compatibilizer content from 0–5 pbw.

Sample code	Max. load (𝑁)	Max. strain (%)
80 : 20	10.2 (9.7)	86 (87)
80 : 20 : 2	11.6 (11.1)	62 (68)
80 : 20 : 5	9.7 (8.7)	67 (64)

The values given in bracket are for samples with surface microporosity.
