Tubing - Medical tubing and custom engineered components

Resins and Compounding

Diablo Sales also represents one of the widest selections of thermoplastic and thermoset polymer tubing products. We specialize in rapid prototyping of custom extrusions as well as continuous dip coat tubing. Depending upon material requirements - ID size ranges from 0.002” to 0.750”. Wall thickness starts at 0.00025” on specific materials. Radiopaque fillers of Barium Sulfate; Bismuth Trioxide; Bismuth Subcarbonate; as well as tantalum and tungsten fillers are available.

Capabilities consist of:
Ultra-thin wall tubing (<.001”)
Multi-lumen extrusions (straight and tapered)
Co-extrusions (striped and multi-layer)
Irradiated high strength balloon tubing
Heat shrinkable tubing
Vacuum-sizing
Profiles
Secondary forming operations
Assembly operations
Braided tubing
Bump tubing
High temperature tubing
High dielectric strength tubing
Signal transmission tubing

Composite tubing
Hybrid composite tubing of different polymer resins can be manipulated to produce specific performance characteristics, such as adding additional strength and/or more flexibility or allowing better bonding properties for laminating layers of materials. Signal transmission properties are another possibility.

Reinforced tubing
Metallic round or flat wire can be used as a braid or coil within the wall of tubing for high torque, high pressure and kink resistant applications and yet be flexible. Picks per inch (PPI) can be varied to also affect the stiffness of the shaft. For instance, a design may require a stiff proximal section and a floppy distal section. Special lubricious polymer liners or hydrophilic coatings can be added on both the ID and OD. These shafts can be assembled with multiple durometers with soft and deflecting tips if required. Non-metallic braids are also available.

Signal transmission and thermocouple wires can be embedded into the walls. Radio opaque platinum coils can also be embedded. Insert molding, thermal and adhesive bonding as well as tipping operations are also available.

Lubricity
Certain tubing applications desire a more lubricious surface, especially with materials that are low durometer or inherently “tacky” to the touch. We can coat both the ID’s and OD’s of tubing with hyrdrophilics or provide lubricious liners such as PTFE / FEP or compounded resins containing medical grade lubricious fillers. The suggested methods will depend upon the desired materials.
