HDPE (High-Density Polyethylene) and UHMW-PE (Ultra-High Molecular Weight Polyethylene) are both polyethylene materials, but their dramatically different molecular weights create fundamentally different properties.
The Critical Difference: Molecular Weight
HDPE has molecular weight of 20,000-500,000 g/mol, while UHMW-PE reaches 2,000,000-6,000,000 g/mol. This 10-100x difference drives all property differences between these materials.
Property Comparison
UHMW-PE offers excellent impact strength (virtually unbreakable) and 3-5x better wear resistance than HDPE with lower coefficient of friction (0.10-0.20 vs 0.20-0.30). HDPE can be injection molded while UHMW-PE cannot. For engineering applications, consider our PA6-CF 絲.
應用
HDPE is used for chemical storage tanks, water and gas piping, and consumer packaging. UHMW-PE is preferred for truck bed liners, conveyor wear strips, marine fenders, and medical implants.

常見問題
What is the typical lead time for custom orders?
Standard lead times range from 3-15 business days depending on order complexity and quantity. Rush orders can often be accommodated with 24-hour turnaround for prototypes.
What quality certifications do you have?
Our manufacturing facility is ISO 9001 certified, and we maintain rigorous quality control processes throughout production. Material certifications and test reports are available upon request.
What is your minimum order quantity (MOQ)?
We offer flexible MOQ starting from just 1 piece for prototypes, scaling up to millions of pieces for mass production. This allows you to validate designs before committing to larger orders.
Can you provide material certification and test reports?
Yes, we provide full material traceability and certification documentation including COA (Certificate of Analysis), physical property test reports, and RoHS/REACH compliance documentation as required.
HDPE vs UHMW-PE — Frequently Asked Questions
What is the main difference between HDPE and UHMW-PE?
The critical difference is molecular weight. HDPE has MW of 20,000-500,000 g/mol, while UHMW-PE reaches 2,000,000-6,000,000 g/mol - a 10-100x difference. This gives UHMW-PE dramatically superior impact strength, 3-5x better wear resistance, and lower friction coefficient.
Can UHMW-PE be injection molded like HDPE?
No. UHMW-PE cannot be injection molded due to its extremely high molecular weight. UHMW-PE must be machined from stock shapes (CNC machining) or compression molded. HDPE can be injection molded using standard methods.
Where can I source HDPE and UHMW-PE materials?
Nylonplastic is a specialized manufacturer established in 2005 with ISO9001/14001/45001/IATF16949 certifications. We supply both HDPE and UHMW-PE in sheet, rod, and tube forms for CNC machining. UHMW-PE with additives also available. Contact us for free samples.
