Product Description

Product Description

What is high molecular weight HDPE granules?

High molecular weight high-density polyethylene is a polyethylene polymer that is created using the gas-phase or slurry process at low temperatures (80 to 110°C) and low pressures (0.48 to 3.1 MPa) when high-efficiency catalysts of the Phillips or Ziegler types are present.  One of the newer types of polyethylene is high molecular weight high-density polyethylene, which has an average molecular weight between 200,000 and 500,000.  It falls into one of two categories: copolymers or homopolymers.  The acronym for high molecular weight high-density polyethylene is HMWHDPE.

Why HMWHDPE  granules or powder are good for making PEX pipe ?

Molecular structure advantages: High molecular weight HDPE has a long molecular chain and a high degree of crystallinity, providing a sufficient molecular chain segment entangling basis for crosslinking reactions. It can form a three-dimensional network structure through crosslinking agents such as peroxides, significantly enhancing the mechanical strength and heat resistance of the pipe

Key Performance	The value of crosslinked tubes/PEX pipe
Chemical resistance	Suitable for transporting corrosive media such as chemicals and gas
Low temperature resistance	Maintain mechanical properties at low temperatures to avoid pipe rupture
Low friction coefficient	The inner wall is smooth to reduce fluid resistance and improve conveying efficiency
Resistance to creep and long-term strength	It can meet the long-term static water pressure demand of drinking water and heating pipe

What are the advantages of HMWHDPE pipes over other pipes?

1. Difference with ordinary HDPE pipe: high molecular weight HDPE crosslinked pipe through chemical crosslinking to further enhance the heat resistance (working temperature up to 80 ℃ or more) and creep resistance, while the ordinary HDPE pipe temperature resistance is lower (usually ≤ 60 ℃)35. 
2. Comparison with metal pipe: light weight (only 1/8 of the steel pipe), easy to install and do not need anticorrosive treatment, and has recyclability, in line with the trend of environmental protection 2

What  need to know before  manufacturing products ?

 Adaptability of cross-linking process: High molecular weight HDPE can be cross-linked by peroxide cross-linking (PE-Xa) and other processes, and professional extrusion machines are needed to ensure stable pipe production.
Flexibility in molding process: It supports various molding methods such as extrusion and winding, especially suitable for manufacturing winding structural wall pipe, which has both high strength and lightweight characteristics, easy installation and excellent anti-leakage performance.

Meet the needs of diversified application scenarios

1. Municipal and industrial fields: Because of their long service life (up to 50 years) and resistance to abrasion and leaks, high molecular weight HDPE crosslinked pipes are used extensively in urban drainage, industrial wastewater treatment, and agricultural irrigation. This lowers maintenance costs.
 2. Transportation of energy and fluids: appropriate for heating systems, gas, and drinkable water 
 3. Extreme environmental adaptability: reliable operation in cold climates, high corrosion, and other challenging circumstances, such as chemical pipelines in chemical companies or drainage pipes in cold regions.

Choose the cost-effective method for transportation 

1. Through an express service (such as FedEx, UPS, DHL, TNT, EMS, etc.)
 --- Benefit: Quick (delivery takes roughly 5 to 10 days), door-to-door --

 ---  The cost is a little high.

 2. Through Air Travel
 --- Benefit: Quick (about 8–12 days), slightly less expensive than Express.
 --- Drawback: You are responsible for picking up the items from the airport.

 3. Transportation by Sea (Ocean) or by  train  

---Benefit: Far less expensive than air or express shipping.
---Slow and requiring you to transport the items from your final port yourself are drawbacks.
