PTFE Coated Mandrels Block Tubing From Shrinking

14944

A full line of blockers coated with Teflon® (forming mandrels) that maintain tight tolerances on the inside diameter of catheter shafts is available from Applied Plastics Co., Inc. of Norwood, Massachusetts.

Applied Plastics’ PTFE Coated Mandrels are offered in stainless steel or nitinol to prevent sticking, block tubing from shrinking, and simplify catheter removal in fuse welding and tipping operations. They are offered in standard 0.005” to 0.070” sizes, in many fractional diameters within ±0.0003” of each other, and custom sizes can be supplied on request.

Featuring a smooth, anti-stick surface that can withstand heat up to 300°C continuous, with excursions up to 371°C, Applied Plastics’ PTFE Coated Mandrels provide a 0.05 coefficient of friction per ASTM-1894. Maintaining an inventory of over 50,000 pieces, the firm can supply precision cut lengths to 12 ft.

Applied Plastics’ PTFE Coated Mandrels are priced depending upon material, size, tolerances, and quantity. Free stainless steel samples, pricing and literature are available upon request.

Superior medical devices require superior coatings.

Our proprietary PTFE Natural® coated mandrels offer unmatched benefits.

low-co-friction

Low Coefficient of Friction

PTFE Natural® coatings provide a coefficient of friction generally in the range of 0.05 to 0.20, depending on the load and sliding speed.

heat-resistance

HEAT-RESISTANCE

PTFE Natural® coatings can operate continuously at temperatures up to 550°F and can be used for intermittent service up to 600°F with adequate ventilation.

non-stick

Non-Stick

Non-Stick Very few solid substances will permanently adhere to a PTFE Natural® coating. While tacky materials may show some adhesion, almost all substances release easily.

chemical-resistance

CHEMICAL RESISTANCE

Chemical environments usually do not affect a PTFE Natural® coating. Only molten alkali metals and highly reactive fluorinating agents are known to affect this coating.

robust-coating

ROBUST COATING

The proprietary PTFE Natural™ coating process enhances the substrate bonding surface to provide optimum lubricity without flaking or cracking.

non-wetting

NON-WETTING

Since PTFE Natural® finishes are both hydrophobic and oleophobic, cleanup is easier and more thorough.
