2. This tubing will stretch and flex but always return to its original shape. Polyurethane combines the best properties of both plastic and rubber. It is commonly used in the construction of epidural catheters, compliant balloon products, and similar medical devices. Heat and cold resistant Continuous use above 225°F is not recommended nor is urethane recommended in hot water over 175°F. Please contact us for details. When to Use Polyurethane Tubing. Electrical Properties. Some of Polyurethane Tubes main properties include: Anti Bacterial Properties. PUR is strong and flexible enough to handle the bending and rubbing, but it's also soft enough to provide additional comfort to the patient. Other Properties of Polyurethane Elastomers. Has high impact resilience ... chemical and gas permeability resistance. Whereas, the Polyurethane tube combines the best properties of both plastic and rubber. No Cracks, Tearing or Swelling. Polyurethane combines the structural and impact characteristics of amorphous materials like polycarbonate, yet offers the excellent chemical resistance of semi-crystalline materials. Both formulations made from non-toxic raw materials conforming to FDA standards for use with wet and fatty food contact surfaces. PUR tubing provides excellent flexibility and resists the kinds of damage that can lead to dangerous leaks. polyurethane products because of their advantage in abrasion and chemical resistance, excellent mechanical properties, blood and tissue compatibility, and structural versatility. Polyurethane, or Urethane, is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. This form of pneumatic tube are suitable mainly because of all their amazing properties above. Because urethane is available in a very broad hardness range (flexible-soft to rigid-hard), it allows the engineer to replace rubber, plastic and metal with the ultimate in abrasion resistance and physical properties. The effect of structure and presence of additives were identified as the major general factors on this regard. Our Polyurethane tubing is REACH, RoHS and ISO compliant, which addresses the production and use of chemical substances, and their impacts on health and the environment. PLEI-TECH ® 10.

It offers abrasion and tear resistance, high tensile and elongation values, and low compression set. In applications where severe wear is a problem, polyurethanes often outperform rubber, plastics, or even metals. The first Polyurethanes were manufactured as millable gums and so could be processed on normal rubber manufacturing equipment. Hot Finished Seamless Tube is produced to o.d. The chart below show the physical properties of polyurethane. ... Industrial Flexible Polyurethane Air Pneumatic Tubing Hose for Gas Pipeline PU tubing Properties: 1. Duke Extrusion offers medical polyurethane tubing in numerous varieties to meet the unique requirements of customer applications.

Typical Properties: Liquid Properties: Base Material Polyurethane Density Part A - Resin (g/ml) 1.01 Density Part B - Hardener (g/ml) 1.06 Part A Viscosity (mPa s @ 23ºC) 1700 Part B Viscosity (mPa s @ 23ºC) 50 Mixed System Viscosity (mPa s @ 23ºC) 300 Mix Ratio (Weight) 2.24:1 Mix Ratio (Volume) 2.34:1 Usable Life (20°C) 17 mins In addition to exceptional physical properties Plei-Tech ® 10 also offers excellent dynamic properties. Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease and abrasion.Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of … Polyurethane bridges the performance gap between rubber and plastic. MANLON -polurethane tubings (tubes) have low weight as compared to rubber hoses. Transparent Polyurethane Tubing (PUR - PU Tubing) Available in Ester or Ether formulations. Our fast, efficient manufacturing processes, superior quality products, and innovative designs help us consistently meet or exceed customer expectations. Chances are, sometime today you have used a product containing polyurethane foam. Once this reaction has occurred, a substance is created that is safe and extremely versatile. The working pressures of our polyurethane tubes are based on the short-term burst pressure at a temperature of 20°C using a 4:1 safety factor. Strong elastic, flexibility. The aromatics use benzene rings to make the resin stronger, and they tend to be less expensive. Polyurethane Tubing Series TU (Metric) Dimensions Metric Model Tube OD (mm) Tube ID (mm) Min. It can have a number of diverse properties (resilience, flexibility, rigidity), depending on the choice of combined substances. Or call us at 831-420-1104 to discuss your project’s polyurethane medical tubing requirements and learn why Duke Extrusion is the medical device industry’s trusted supplier of medical-grade PUR tubing! Compression By the 1950s, polyurethanes were being used in adhesives, elastomers and rigid foams and, in the latter part of the same decade, flexible cushioning foams similar to those used today. Polyurethane tubes can be manufactured in many colors. Plei-Tech ® 10 is a very high performance polyurethane that is best suited for the most demanding applications. Duke Extrusion is a division of Duke Empirical, Inc., a contract manufacturer and developer of innovative medical devices. and wall dimensions. Polyurethane has an excellent electrical insulating property. Long, flexible segments, contributed by the polyol, give soft, elastic polymer. Lightweight polyurethane tubing handles five to ten times more wear and tear than typical rubber hoses and it resists hydrolysis, oil, and cold temperatures.
