Product catalog summary

Overview: The document provides comprehensive information on medical tubing products by Polygon Company, focusing on specifications, applications, and properties. All products are USP Class VI approved, suitable for medical use.

Braided Polygon Medical Tubing: This high-strength composite material is used in disposable and reposable applications, typically ranging from 5-20mm. It is not recommended for autoclave or other sterilization techniques.

Circ-Wound Polygon Medical Tubing: Used in high-volume applications like surgical cannulas, this tubing offers high strength with thin walls (0.015”) but is not suitable for reusable applications.

PolyMed Generation II Medical Tubing: Designed for minimally invasive laparoscopic surgical instrumentation, available in CW or UD constructions. It is reusable and available in sizes from 3 to 20mm.

PolyMed Multi-Lumen Medical Tubing: The highest strength multi-lumen tubing available, with some restrictions on lumen size and orientation. It is reusable and available in sizes from 3 to 20mm.

Carbon Fixator Rods: Made from a pultruded carbon fiber, vinyl ester composite, offering high strength and low weight, used for cranium halos and limb fixation systems.

Physical and Electrical Properties: Lists typical physical properties such as tensile strength, flexural strength, specific gravity, and moisture absorption. Electrical properties include dielectric strength, varying by composite design.

Fabrication Guidelines: Includes specifications for wall thickness, ID, length tolerance, concentricity, straightness, and hole dimensions.

Product Advantages and Disadvantages: Each product section outlines specific advantages like high strength and cost-effectiveness, and disadvantages such as cost implications for higher volumes and sterilization limitations.

Conclusion: The document highlights the suitability of various medical tubing products for different applications and the trade-offs involved.

Composite Materials Overview: Discusses properties and performance of composite materials, focusing on dielectric strength, reusability, and chemical resistance in sterilization processes.

Part Survival Under Electrical Stress: Evaluates PolyMed II constructions under 3000 volts at 60 Hz. None failed under certain conditions, but failures occurred after extensive autoclave cycles.

Dielectric Strength and Water Absorption: Provides data on dielectric strength during sterilization cycling and graphs on water absorption, indicating percentage weight gain under different conditions.

Flexural Modulus and Strength: Tests flexural modulus and ultimate flexural strength of materials like Polymed I, Polymed II UD - Black, and Vectra A-130 during sterilization cycling, presented in psi.

Additional Products and Advantages: Highlights other Polygon products like PolyLube composite bearings and AeroSlide composite cylinder tubing, emphasizing high load capacity, corrosion resistance, and suitability for various applications. Discusses Continuous Fiber Thermoplastics (CFT) for strength and recyclability.

About Polygon: Founded in 1949, Polygon Company is a leader in composite materials, offering a wide range of manufacturing capabilities and products globally.

Bearings:Polygon PolyLube composite bearings and bushings are ideal for any high load, low speed application. Superior bearing capabilities make these composites the perfect choice for use in industrial and medical equipment such as hospital beds, respirator systems, lift tables, x-ray and MRI tables as well as a variety of other applications. Because PolyLube bearings are non-corrosive, they work well in waste water treatment valves, outboard motors, boat trailers, and moving parts for off- shore oil drilling rigs.
