35mm Polyethylene HDPE Rods Plastic Bar
Analysis of HDPE Rod's Core Performance
1. Excellent Chemical Stability (Extremely Corrosion Resistance)
Resistant to most acids, alkalis, salts, and organic solvents (such as sulfuric acid, hydrochloric acid, sodium hydroxide, ammonia, alcohol, gasoline, etc.);
It exhibits virtually no reaction with common chemicals, making it a commonly used anti-corrosion material in chemical, environmental protection, electroplating, and wastewater treatment equipment;
It has relatively weak resistance to strong oxidizing acids (such as concentrated nitric acid and sulfuric acid at high temperatures) and aromatic hydrocarbons (such as benzene and toluene).
It is suitable for chemical plants, environmental protection equipment, acid and alkali storage tanks, electrolytic cells, pipe sheathing, and tank linings.
2. Good mechanical strength and rigidity
Tensile strength: approximately 20-38 MPa
Flexural strength: approximately 25-45 MPa
Good compressive strength, suitable for structural support of small and medium loads
Although not as strong as engineering plastics (such as PA, PC, and ABS), it has an above-average strength level among plastics.
Suitable for load-bearing structural components, protective columns, mechanical components, partitions, spacers, etc.
3. Excellent impact resistance and toughness
Maintains excellent impact resistance even in low-temperature environments (e.g., -20°C or even lower) and resists brittle cracking.
Compared to materials like PVC and PP, HDPE is less susceptible to brittleness at low temperatures and offers superior overall toughness.
4. Odorless, non-toxic, and safe and hygienic
Complies with FDA, EU, and LFGB food-grade standards and can be used in food processing, pharmaceuticals, drinking water equipment, laboratory equipment, and other applications involving human contact or food.
The smooth surface resists impurities and is easy to clean, making it suitable for clean environments.
5. Excellent environmental resistance
Balanced high and low temperature resistance:
Long-term operating temperature: Approximately -50°C to +60°C (recommended)
Short-term resistance to 80°C
Remains flexible and resists brittleness at extremely low temperatures
Ultraviolet resistance is average (unmodified); UV-resistant grades are recommended for outdoor use.
Aging resistance, frost resistance, and hydrolysis resistance
6. Lightweight, easy to process, and low-cost
Density: Approximately 0.94 to 0.96 g/cm³, slightly lighter than water and significantly lighter than metals and engineering plastics;
Flexible processing: Suitable for secondary operations such as cutting, drilling, turning, grinding, hot-melt welding, bonding, and surface polishing;
Excellent cost-effectiveness: Low cost yet balanced performance makes it an ideal material for replacing steel and wood with plastics.
7. Excellent electrical insulation properties
High volume resistivity makes it an excellent general-purpose insulating material, suitable for non-high-voltage insulation in electrical equipment.
Why Choose HDPE Rod?
HDPE Rod is a high-performance, general-purpose plastic rod that is corrosion-resistant, impact-resistant, lightweight, safe, easy to process, and low-cost. It is a key material for replacing steel and wood with plastic in modern industry, chemicals, food, construction, and machinery.
It is particularly suitable for various structural components, support rods, protective columns, guide rods, and spacers requiring corrosion resistance, impact resistance, structural support, lightweight, non-toxic, and hygienic properties, while also maintaining cost-effectiveness. It is a truly versatile engineering plastic solid rod.
