High Density Polyethylene (HDPE)

High Density Polyethylene (HDPE)


High Density Polyethylene or commonly known as HDPE, is a type of polyethylene thermo plastic. It is manufactured from the semi-crystalline polyethylene (PE) family.  HDPE is used as a plastic material form at Magna Plas for a wide range of products including plastic HDPE round rod and bars, HDPE parts and components and HDPE custom extruded profiles. 

HDPE or High Density Polyethylene is well known for its excellent combination of durability, light weight and the ability to be shaped easily.  According to byju’s, HDPE is a common plastic that astonishingly accounts for over 34% of the global plastic market.  

HDPE has outstanding advantages and benefits including its resistance and sustainability.  HDPE is immune to such pressures of what other materials may not withstand including immune to rusting, rot, mildew and mold.

In the system we live in today, sustainability allows us to maintain the needs of the present, but without compromising the future generations to come.  In addition to the benefits of using HDPE High Density Polyethylene as a material for what we need now, it is also easily recyclable. Magna Plas Victoria is committed to recycling plastic where viable and committed to ensuring we apply sustainability where we can as a business.  We can produce entire parts and components, extruded round rod and bars from recycled material at a customers request.  We also have access to Australia’s highest quality of virgin raw plastic materials.  We are able to fulfil all needs within the industry.
