Polyethylene is classified into several different categories based

mostly on its weightand branching.

These both determine its Championproperties.

Few Important Types Include:

UHMWPE(ultra high molecular weight PE)

HDPE(high density PE)

LDPE(low density PE)

CLASSIFICATION

Manufacturing Types:

Compression molding

Blow Molding

UHMWPE: ultra high molecular weight polyethylene

Extremely long Linear chains and Very packed

structure.

CHAMPION PROPERTIES:

Tough material Highest impact strength

BULLETPROOF JACKET

TROLLEY WHEEL

HIP IMPLANT


5/12

HDPE(high density polyethylene)


More Tensile strength (doesnt deform easily). Lower Ductility (breaks easily).

Long Linear chain structure.

BOTTLES

PIPES


6/12

LDPE(low density polyethylene)

Branching (weaker) structure and Molecules

are less tightly packed.


Lower Tensile strength (deforms easily) Higher ductility (doesnt break easily)

Polyethylene film (Low Density Polyethylene) with a thickness

of 0.024-0.04mm, normally sold at general market retailers as a

"plastic bag."Low-density polyethylene softens when it is heated at 70 to 90 degrees

Celsius.

Taking advantage of this, different types of soldering irons and press is

used to process the whole sequence from creating fabric to molding

parts, joining, and finishing the details.

Layering the polyethylene films, they are heated and pressured slowly with a

soldering iron. By repeating this process over again, the width and strength are

increased and a fabric is created with natural shrinkage, wrinkles, uneven

surfaces, and tactile texture.

A soldering iron is used to weld things by hand, from

the assembling process to joining

1. Sugarcane is crushed , fermented and

distilled into ethanol,

2. Then

transformed into

polyethylene

pellets.

3. Extruded into yarn

4. Woven into Fabric.
