      1000             500
PE-UHMW 1000 & PE-HMW 5000 Properties Comparison



Distinguishing between PE-HMW 500 and PE-UHMW 1000 is the molecular weight.
PE-HMW 500 is a high molecular low pressure polyethylene with a molecular weight
approximate 500.000 g/mol, and also called as PE-500.
PE-UHMW 1000 (PE-1000) is a high molecular low pressure polyethylene with a
molecular weight approximate >3.500.000 g/mol .

            PE-UHMW 1000                              1000 Based on Sand Slurry Test
Molecular weight difference affected the properties of PE-UHMW, including: density,
impact strength, and abrasion resistance (wear resistance) that shown on Fig 1. The
properties differences shown PE-UHMW 1000 advantages over PE-HMW 500, which
include:

1. PE-UHMW 1000 density (0.92 g/cm3) is lighter than PE-HMW 500 density (0.95
   g/cm3) .

2. PE-UHMW 1000 more tough 11 times better than PE-HMW 500 in receiving impact
   force.
   PE-UHMW 1000 impact strength: 170 kJ/m2
   PE-HMW 500 impact strength: 15 kJ/m2

3. Abrasion resistance (wear resistance) of PE-UHMW 1000 is 4 times better than PE-
   HMW 500 (based on sand slurry test ISO 15527)
   PE-UHMW 1000 wear resistance rate: 100 %
   PE-HMW 500 wear resistance rate: 400 %

Due significant properties difference (impact strength and wear resistance) PE-HMW
500 can’t replacing PE-UHMW 1000 , which will affect on usage time.
PE-UHMW 1000 TRIBOLOGY

 Many engineering application need a good tribology properties. Tribology is the
 branch of engineering that concerned with interacting surface in relative motion
 under applied load. Properties of tribological system are wear and friction.

 Wear is the progressive loss of material from surface in relative motion with to one
 another. The wear rate is influenced by test condition; pressure and velocity, and
 defined as the rate of height loss in a specific wear environment (sand slurry test,
 block on ring, thrust washer test, etc). The lower wear rate, the better the resistance
 to wear.

 Friction is the resistance to sliding motion between two surface. It is a dimensionless
 property (ɥ), varying with velocity, pressure, temperature, lubrication, the roughness
 and nature of the contacting surface.

 PE-UHMW 1000 tribology properties is excellent due its very low wear rate (4 times
 PE-HMW 500) and low coefficient of friction (15), and very suited for engineering
 application in harsh environment including: coal hopper, dump truck, or conveyor.

 In engineering application that need excellent sliding properties including trybology
 properties, material that can meet this requirement is only PE-UHMW 1000.
Indonesia PE-UHMW Market Condition

 PE-HMW 500 known in Indonesia market is not the real PE-500, but mostly PE-HD
 (High Density Polyethylene) with molecular weight is way below of 500.000 g/mol
 (between 250.000 g/mol – 400.000 g/mol). This PE-HD is made by Asian Countries like
 China, Korea, and Taiwan.

 Since PE-HD molecular weight is below of PE-HMW 500 molecular weight, the
 properties will be very weak compared with PE-UHMW 1000. Many people thought
 that PE-HMW 500 or PE-HD strength is only a half of PE-UHMW 1000 strength, but
 actually the difference is very significant as explained below:

  PE-UHMW 1000 more tough 11 times than PE-HMW 500, and 17 times toughness
   than PE-HD (impact strength: 10 kJ/m2).

  PE-UHMW 1000 wear resistance 4 times better than PE-HMW 500 and PE-HD

 This condition worsen by no explanation or education for customer about difference
 between PE-UHMW 1000, PE-HMW 500, and PE-HD by it’s seller or distributor.

  • 4. Molecular weight difference affected the properties of PE-UHMW, including: density, impact strength, and abrasion resistance (wear resistance) that shown on Fig 1. The properties differences shown PE-UHMW 1000 advantages over PE-HMW 500, which include: 1. PE-UHMW 1000 density (0.92 g/cm3) is lighter than PE-HMW 500 density (0.95 g/cm3) . 2. PE-UHMW 1000 more tough 11 times better than PE-HMW 500 in receiving impact force. PE-UHMW 1000 impact strength: 170 kJ/m2 PE-HMW 500 impact strength: 15 kJ/m2 3. Abrasion resistance (wear resistance) of PE-UHMW 1000 is 4 times better than PE- HMW 500 (based on sand slurry test ISO 15527) PE-UHMW 1000 wear resistance rate: 100 % PE-HMW 500 wear resistance rate: 400 % Due significant properties difference (impact strength and wear resistance) PE-HMW 500 can’t replacing PE-UHMW 1000 , which will affect on usage time.
  • 5. PE-UHMW 1000 TRIBOLOGY Many engineering application need a good tribology properties. Tribology is the branch of engineering that concerned with interacting surface in relative motion under applied load. Properties of tribological system are wear and friction. Wear is the progressive loss of material from surface in relative motion with to one another. The wear rate is influenced by test condition; pressure and velocity, and defined as the rate of height loss in a specific wear environment (sand slurry test, block on ring, thrust washer test, etc). The lower wear rate, the better the resistance to wear. Friction is the resistance to sliding motion between two surface. It is a dimensionless property (ɥ), varying with velocity, pressure, temperature, lubrication, the roughness and nature of the contacting surface. PE-UHMW 1000 tribology properties is excellent due its very low wear rate (4 times PE-HMW 500) and low coefficient of friction (15), and very suited for engineering application in harsh environment including: coal hopper, dump truck, or conveyor. In engineering application that need excellent sliding properties including trybology properties, material that can meet this requirement is only PE-UHMW 1000.
  • 6. Indonesia PE-UHMW Market Condition PE-HMW 500 known in Indonesia market is not the real PE-500, but mostly PE-HD (High Density Polyethylene) with molecular weight is way below of 500.000 g/mol (between 250.000 g/mol – 400.000 g/mol). This PE-HD is made by Asian Countries like China, Korea, and Taiwan. Since PE-HD molecular weight is below of PE-HMW 500 molecular weight, the properties will be very weak compared with PE-UHMW 1000. Many people thought that PE-HMW 500 or PE-HD strength is only a half of PE-UHMW 1000 strength, but actually the difference is very significant as explained below:  PE-UHMW 1000 more tough 11 times than PE-HMW 500, and 17 times toughness than PE-HD (impact strength: 10 kJ/m2).  PE-UHMW 1000 wear resistance 4 times better than PE-HMW 500 and PE-HD This condition worsen by no explanation or education for customer about difference between PE-UHMW 1000, PE-HMW 500, and PE-HD by it’s seller or distributor.
