Low-Density Polyethylene Tubing: Features, Applications, and Technical Specifications 

What is LDPE Tubing and Why Is It a Smart Choice? 

Low-Density Polyethylene tubing, known as LDPE tubing, is a versatile food-safe, and chemically resistant tubing widely used in industrial automation, agriculture, food &beverage processing, and medical environment. Compared to High-Density Polyethylene (HDPE), LDPE tubing offers excellent flexibility and outstanding chemical resistance—making it ideal for low-pressure fluid transfer systems.

At SHPI, our LDPE tubing complies with FDA standard, ensuring it is non-toxic and odorless for safe contact with drinking water and food related application. From household drinking water lines and brewery beer transfer to chemical handling in industrial plants, SHPI's LDPE tubing offers safety, efficiency, and cost-effectiveness solution.

Key Benefits of SHPI LDPE Tubing

  • Superb Flexibility in Extreme Conditions
SHPI's low-density polyethylene tubing maintaining excellent bending and anti-kink performance even at temperature as low as -45°C (-50°F), making it ideal for cold environments where durability and bending performance are critical. 
  • Excellent Chemical Resistance
LDPE tubing offers distinguished resistance to a variety of acids, bases, salts, and most organic solvents, helping protect the purity and safety of fluid transfer systems.
  • High Visibility & Clean Appearance
Natural low-density polyethylene is milky and nearly transparent, allowing for easy visual inspection of internal fluid flow and early detection of abnormalities and contamination at the early stage. 
  • Lightweight & Cost-Efficient

Much lighter than metal tubing, LDPE reduces shipping and handling costs. It also features excellent environmental stress crack resistance (ESCR), ensuring long-term durability in outdoor and high-load environments.

Common Application of Low-Density Polyethylene Tubing

Thanks to its versatility, low-density polyethylene tubing serves as the ideal piping solution across a wide range of industries—from precision automation equipment to large-scale agricultural irrigation.

Food & Beverage Applications

  • Drinking water piping systems
  • Food and beverage processing pipelines
  • Tubing for dairy, juice and brewery production line

Industrial and Automation Applications

  • Low-pressure fluid transfer in chemical plants
  • Cooling water circulation piping systems
  • Pneumatic tubing for compressors and automation equipment
  • Tubing for cleaning systems
  • Specialized tubing for semiconductor, automotive, agriculture and construction sectors
