Small Diameter Plastic Tubing Materials

We produce mini plastic tubing from a range of materials, including:


A durable plastic that can maintain its tough structure, dimensional stability and impact resistance over time. It can be machined, drilled, cut and sawed and is easily joined with solvents or adhesives.


An extremely light thermoplastic that exhibits excellent dimensional stability and electrical properties. It also has good surface hardness, chemical resistance and easy coloration. In places where fluoropolymer tubing is typically used, polypropylene tubing can be implemented as a relatively low-cost alternative.


This tubing product is lightweight, flexible and exceptionally durable. The inertness of polyethylene makes it is ideal to safely transfer numerous types of chemicals, fluids and materials. Additionally, due to the chemical inertness, the polyethylene tubing forms a good barrier protecting it from gases, vapors, and moisture.


This tubing product is valued for its versatility, thermal stability, and high melt strength. It also displays excellent rigidity. Polystyrene tubing is commonly used within the film, tape, textile and paper industries.


This is a highly versatile tubing product. It is extremely flexible and is an excellent material for clear tubing applications. PVC is commonly used within the construction industry for a wide range of applications.

In addition, we extrude miniature plastic tubing in various grades and formulations to meet regulatory requirements for custom applications. We can provide plastic tubing in FDA grades, flame retardant grades to meet UL requirements, and with UV stabilizers for outdoor applications. Other specialized varieties are available upon request.
