Polyethylene Tubing

Differences Between Polyurethane & Polyethylene Tubing

Polyurethane is a highly stretchable material. It provides excellent flexibility, heat resistance and cracking and puncture protection, which means that it is highly useful for applications that must withstand harsh environments. Conversely, polyethylene provides increased moisture protection, while maintaining good strength and durability features. Since it is FDA approved, poly tubing is often used within the food and beverage industries.

PE Tube Advantages

Our LLDPE polyethylene tubing and Liquiflex POE tubing products provide efficient, clean fluid handling capabilities for hospitals, research laboratories, food and beverage manufacturers, agriculture, and more.

  • Resists cracking
  • Impermeable to gas and moisture
  • Corrosion resistant
  • Economical
  • Flexible
  • Ideal for fluid-handling applications
  • Puncture resistant​

Polyethylene Tubing Options

Even though it is not as flexible as polyurethane, polyethylene still provides excellent moisture protection and resistance from cracks and puncture related problems. Due to its strength and durability, polyethylene is often used to create plastic bottles as well as corrosion-resistant pipes. At Freelin-Wade, we are one of the biggest polyethylene tubing suppliers in the nation. We can provide both LLDPE tubing and Liquiflex POE tubing in a wide range of materials and sizes.

Linear Low Density Polyethylene

Freelin-Wade’s linear low density polyethylene (LLDPE) tubing provides increased flexibility, tensile strength and conformability over standard polyethylene tube. It is known for its environmental stress crack resistance (ESCR) and puncture resistance. LLDPE tube is impermeable to gases and moisture.

Liquiflex POE Tubing

In addition to LLDPE tubes, we also offer a more flexible poly tubing product called Liquiflex. Liquiflex offers three highly beneficial qualities in one tube: chemical resistance equal to polyethylene, flexibility on par with polyurethane, and excellent memory. Liquiflex can be made into self-storing, retractable coils just like polyurethane and nylon.

Liquiflex POE tubing material comes from the same family of polymers as polyethylene and polypropylene, and is ideal for fluid handling, low pressure applications, or anywhere users need flexibility and FDA compliance.

Product Lineup

EVA Lined Tubing

Freelin Wade EVA Lined Tubing
Known for its high-strength and flexibility, Ethyl Vinyl Acetate (EVA) lined tubing is ideal for beverage lines and other applications where odorless, tasteless tubing is needed. Freelin-Wade’s EVA Lined LLDPE Beverage Tubing is designed with an inner layer of EVA and outer layer of LLDPE.
Our EVA lined LLDPE tubing is perfect for commercial or retail beverage OEMs, breweries, and even home brewers that need replacement tubing for beverage systems.

EVA Lined Beverage Tubing Features

  • Constructed with NSF51, NSF18, and FDA Compliant EVA liner.
  • Compatible with standard push-to-connect fittings or compression style fittings.
  • Temperature range: –40°F to +150°F.
  • Available in natural – custom colors available if needed,
  • Package sizes from 100ft to 1000ft depending on tube size and application need

LLDPE Tubing

Freelin Wade LLDPE Tubing
Linear Low Density Polyethylene (LLDPE) is blended form of LDPE. This form of polyethylene tubing provides much more flexibility, tensile strength, and more conformability. LLDPE tubing is also the most flexible of the plastic sheeting films, while providing increased softness and pliability. LLDPE is used for numerous applications and can be blended into other films to give them more flexibility and extra strength.

Pneumatic LLDPE tubing’s greatest advantage over standard low density polyethylene (LDPE) is its superior environmental crack resistance, or ESCR. Environmental stresses that can affect the longevity of LDPE tubing include chemical exposure, aging, connection to barb-type fittings, and high-vibration connections with compression fittings.

Pneumatic LLDPE Tubing Features & Benefits

  • Greater tensile strength than LDPE tubing
  • Higher burst pressure
  • Superior stress and crack resistance
  • High puncture resistance
  • Impermeable to gasses and moisture
  • Tasteless and odorless
  • Superior dielectric properties
  • Lightweight
  • Available in black, gray, red, green, blue, yellow, orange, clear, and purple

Liquiflex-POE Tubing

Freelin Wade Liquiflex-POE Tubing
High-quality flexible tubing is imperative for safely transferring fluids without cracking or contaminating the chemical composition of the liquid or material. Freelin-Wade has developed Liquiflex, a new polyolefin elastomer tube ideal for conveying liquids and fluids in low-pressure applications. This FDA-Approved tubing provides all the chemical resistant properties of LLDPE tubing, and offers even greater flexibility than polyurethane all in a single tube. Freelin-Wade can fill high-volume orders of standard and custom coiled tubing as individual tubes or in multi-tube bundles.

Liquiflex Tubing Properties

Liquiflex is made from a polyolefin elastomer (POE) resin that comes from the same family of polymers as polyethylene and polypropylene. Like these other olefins, it is resistant to solvents and chemically inert; unlike those resins, it is an elastomer, making it highly elastic. Liquiflex has low pressure ratings, particularly in warm environments Liquiflex is UV resistant and formed from FDA-Approved resins.

Liquiflex POE Tube Specifications

  • Temperature Range: -40°F to 150°F (-40°C to 66°C)
  • Vacuum Rating: to 28” Hg
  • Diameter Tolerance: ±0.005”
  • Durometer: 92A
  • Tube Markings: FW specifications
  • Working Pressure: 3:1 safety factor
  • Resin Compliance: FDA

Benefits of Liquiflex-POE (Plastic) Tubing

The primary benefit of Liquiflex-POE tubing is its superior flexibility compared to other plastic tubing. Liquiflex will bend and spring back to its original shape, making it popular as coiled tubing of various lengths. Liquiflex is FDA-Compliant and resistant to most chemicals, making it ideal for pharmaceutical and food processing applications. Additionally, Liquiflex exhibits low outgassing, so the resin of the tubing won’t contaminate or alter the media being transferred. Liquiflex handles low-pressure fluids very well, and can be bonded into multi-tube bundles to better organize your fluid transfer processes.
