HDPE Shrinkage Because HDPE is a crystalline material the shrinkage is high about 0.015 0.04mm/mm or 1.5 4. This will depend on the degree of orientation and the level of crystallinity in the part and that of course depends on the processing conditions and even the design of the part that youre manufacturing.

A centimeter of UHMW PE is like three milk jugs together. On YouTube I see many people use a shelf full of water filled jugs like these for target practice and to measure bullet penetration.
HDPE is known for its high strengthtodensity ratio. The density of HDPE can range from 930 to 970 kg/m 3. Although the density of HDPE is only marginally higher than that of lowdensity polyethylene HDPE has little branching giving it stronger intermolecular forces and tensile strength than LDPE.
HDPE is the cheapest machinable plastic you can buy. One inch HDPE is 250 bucks for a 48quotx96quot sheet. The price is pretty much by the cubic inch so you can extrapolate any size up to six inches thick. So far this year I have bought thirty sheets of one inch HDPE. Today I sent three sheets to that big scrap pile in the sky.
When basketball backboards made from polycarbonate are used outdoors they become very ugly due to yellowing cloudiness and brittle in a matter of 35 years. This actual means a polycarbonate backboard though marketed as a bulletproof backboard will actually become brittle and very easy to break when used outdoors.
As such any body armor that has Kevlar has the Kevlar sheets covered with a thick fabric that keeps the sunrays and moisture away. The body armor also comes with very precise instructions on how to properly clean it when need be. To protect against blunt trauma Kevlar bulletproof vests are reinforced with steel or ceramic plates.
Highdensity polyethylene HDPE or polyethylene highdensity PEHD is a polyethylene thermoplastic made from petroleum.HDPE is defined by a density of greater or equal to 0.941 g/cm3. HDPE has a low degree of branching and thus low intermolecular forces and tensile strength.

It is about 1.25 inches thick and can protect against three shots from a .44 magnum an extremely powerful revolver. To achieve greater levels of protection it is typically necessary to layer glass with polycarbonate plastic. This creates a very thick heavy and durable glass.
Well this is pretty cool At just 10mm thick which is around of an inch both the glass fiber and the kevlar managed to stop the.22 bullet. The glass fiber didnt even bend and the largest part of bullet just bumped right off theres a tiny bit stuck inside and the layers did split but thats about it.
