How to Select and
Process the High
density plastic
Health, environment and safety issues have been driving the demand for
lead replacements, but it isn’t as easy as it looks like. Selecting and
working with high-density plastics requires special care.
The choice of high-density filler additive, as well as the selection of polymer
matrix, has a huge impact on the properties of the material.
High-gravity compounds have a specific gravity that ranges between 2
to 11, unlike normal plastics which have a specific gravity of 1.0. To put
things into perspective, even 40% long-glass reinforced nylon has specific
gravity of 1.74. As a result
Governments are now beginning to root out the use of lead, and this is where
high-gravity compounds can really help you. They can replace lead in
applications such as radiation shielding in the fields of x-ray equipment and
nuclear medicine.
There are all kinds of heavy plastics available and you can always mix
different resin matrixes with high-density additives such as metal powders
and minerals.
Different high-density plastics have different properties and this has a
major impact on mold design. One can always use traditional practices such
as two-plate molds or three-plate molds and hot runner systems or cold
runner systems
The simplest way to process high-density plastics is to use the injection
molding method. Other methods commonly seen include sheet extrusion,
profile extrusion and thermoforming.
Profile extrusion and thermoforming, Here are a few things that you need to
keep in mind while processing heavy plastics.
