KMT-PVDF-SR is a cross-linked polyvinylidene fluoride (PVDF) heat shrink tubing with excellent chemical and abrasion resistance, high dielectric strength and excellent tensile strength. Its uniform structure (even distribution of properties) gives it consistency and high performance, and KMT-PVDF-SR heat-shrinkable tubing is essentially free of pinholes, lines, cracks or impurities, etc. KMT-PVDF-SR is a semi-rigid material with a transparent colour and provides excellent wear protection for rigid laparoscopes and internal instruments.
