14. Serving a wide range of applications
Laparoscopic instruments, trocars, and electrosurgical device protection:
MT1000, MT2000, MT3000, MT5000, MT-PBX and MT-FEP – TE’s heat shrink portfolio offers a full range of products that can be selected for sterilization versatility, flexibility or rigidity, lubricity, and chemical and abrasion resistance. From protective outer sheaths for laparoscopic and electrosurgical shafts, to lubricious layers between inner and out shafts in high RPM applications such as arthroscopic bone shaving.
Manufacturing process aids:
MT-LWA, MT5000 and MT-FEP: TE offers both fluoropolymer and polyolefin-based materials for process aid applications.
MT-FEP – With shrink ratios up to 1.7:1, TE’s MT-FEP maintains longitudinal change <10% to reduce lot-to-lot variability and enable consistent shaft reflow processes.
MT-LWA and MT5000 – With shrink ratios up to 4:1, TE’s MT-LWA is perfect for reflow applications where FEP shrink ratios are not suitable. MT-LWA and MT5000 have excellent tear propagation, allowing it to peel easily and without the use of blades. It’s optical clarity and optional controlled shrink force make it an exceptional process aid for hot jaw bonding and laser-weld application, such as balloon bonding.
Interventional shaft encapsulation:
MT-PBX and MT-PBX/PBX – Single and dual wall PEBA heat shrink with walls down to 0.001” and shrink ratios up to 4:1
MT-PBX – Single wall PEBA-based heat shrink. Recovered wall thickness down to 0.001” to provide thin wall protection of material transitions or entire catheter shafts; Adds rigidity to select sections of otherwise flimsy substrates
MT-PBX/PBX – Dual wall PEBA; outer layer will heat shrink and inner layer will reflow to join with underlying braid to create a braided catheter shaft without the use of a process aid
Protection and strain relief for joints and pivot points:
MT1000, MT3000, MT5000, MT5510, MT-PBX, and MT-FEP – Provide durability and protection from temperature and chemicals through repeated flexure.
