The new Altera MT-PBX tubing uses a single-wall construction of polyether block amide copolymer (PEBA) to achieve shrink ratios of either 2:1 or 4:1, with custom ratios available.

Using PEBA materials that meet U.S. Pharmacopeia Class VI standards, the tubing withstands repeated sterilisation by autoclave, gamma radiation, ethylene oxide, steam, and dry heat.

Applications include strain relief, mechanical protection, insulation, and colour coding. Altera MT-PBX medical tubing is available in application-specific formulations and an array of colours. Shore D durometer hardnesses range from 25D to 72D to allow use where either rigid or flexible tubing is required. Full recovery occurs at 190°C, with the time depending on the Shore D value. Options include an interior adhesive layer and radiopaque fillers.
