What is Polyolefin Tubing
Polyolefin tubing, made from polyolefin as the base material, is a cross-linked modified polymer. Due to its thermal shrinkage, Polyolefin Tube can also be referred to as Polyolefin heat shrink tubing. After heating, it will shrink to 1/2 or 1/3 of its original diameter, tightly adhering to the coating. After cooling, it forms a dense, waterproof, dustproof, insulating, and wear-resistant protective layer, thus achieving the function of protecting the target object.
Feature Types of Polyolefin Tubing
Polyolefin tubing is widely used. Due to varying demands for its mechanical properties and heat shrinkable behavior, Polyolefin tube is often categorized based on the following four typical and practical characteristic types: rigid, semi-rigid,flexible, and heat shrink.
Polyolefin tubing made from PE, including LDPE, LLDPE, PP,Ethylene Vinyl Acetate Copolymer can indeed be classified as rigid, semi-rigid, or flexible based on their physical properties.
PE and EVA materials do not inherently possess heat-shrinkable properties; only after undergoing irradiation crosslinking can they mostly be used as heat shrink tubing.

Performance Characteristics of Different Types of Polyolefin Tubing
◆ PE Polyethylene Tube
PE (Polyethylene) Tube is a versatile and lightweight tubing material known for its excellent chemical resistance and durability. It is commonly used in fluid transfer applications for water, air, and other non-aggressive fluids.
PE tubing is flexible, easy to install, and offers good impact resistance, making it ideal for industries like agriculture, construction, and automation. Available in various sizes,
PE tubes are an economical choice for both low-pressure and medium-pressure systems.
◆ LDPE Low Density Polyethylene Pipe
Low-density polyethylene, also known as high-pressure polyethylene (LDPE), is the lightest variety of polyethylene resin, appearing as milky white, tasteless, odorless, non-toxic, and non-glossy waxy particles.
It possesses good flexibility, elongation, electrical insulation, transparency, processability, and some degree of breathability. It exhibits relatively good chemical stability, being resistant to alkalis and general organic solvents.
◆ LLDPE Linear Low Density Polyethylene Pipe
Linear low-density polyethylene (LLDPE) is formed by copolymerizing ethylene with a small amount of α-olefin, resulting in a molecular structure with very short copolymer monomer side chains attached to the linear ethylene main chain.
Linear low-density polyethylene is a milky white granule that is non-toxic, tasteless, and odorless, with a density ranging from 0.918 to 0.935g/cm3.
Compared to LDPE tubing, it has a higher softening temperature and melting temperature, with advantages such as greater strength, good toughness, rigidity, heat resistance, and cold resistance. It also exhibits good environmental stress cracking resistance, impact strength, tear strength, and resistance to acids, alkalis, organic solvents, etc., making it widely used in industrial, agricultural, medical, sanitary, and daily life products.
◆ PP Polypropylene Tube
PP polypropylene has a lower heat deformation temperature (100°C), low transparency, low glossiness, and low rigidity, but it has stronger impact resistance. The impact strength of PP increases with the increase of ethylene content. The Vicat softening temperature of PP is 150°C. Due to its high crystallinity, this material exhibits good surface stiffness and scratch resistance.
Polypropylene tubing is non-toxic, corrosion-resistant, non-scaling, heat-resistant, and corrosion-resistant, with smooth inner walls and lightweight. They are mainly used in urban water supply, chemical industry, petroleum, chlor-alkali, pharmaceuticals, dyes, pesticides, food, metallurgy, electroplating, environmental protection, water treatment, and other industries.
◆ EVA Ethylene Vinyl Acetate Copolymer
EVA is an elastic polymer that can produce materials with softness and flexibility similar to rubber. This material exhibits good transparency, glossiness, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof performance, and resistance to ultraviolet radiation.
EVA has a distinctive vinegar-like odor and can compete with rubber and ethylene-based polymer products in many electrical applications. It is often used in the production of footwear, packaging materials, industrial products, medical devices, household items, sports equipment, and more.
