When choosing, specifying or installing a chemical tank you have more choice that ever before. Here at Carbery Tanks, our products our Chemical Tanks are manufactured from a specialist Medium Density Polyethylene. This material is  specifically designed for specialist chemical storage applications and characterised by excellent chemical resistance characteristics.

What is Medium Density Polyethylene?

Polyethylene is the most commonly used type of plastic in the world. Medium Density Polyethylene(MDPE) is a widely used type of polyethylene. MDPE is defined by its density, of which its range is anywhere between .926 & .940 g/cm3. It is also defined by its ability to be melted, cooled and reheated, without losing any of its original properties. The material will not go up in flames, but rather melt or liquify in that situation. This quality of medium density polyethylene is important for its use in chemical storage tanks.

Benefits of Medium Density polyethylene(MDPE)Tanks   

Glass Reinforced Plastic (GRP/Fibreglass) has been a long established manufacturing process.  It has proven itself ideal for chemical storage applications over the years. However at Carbery Tanks, our bulk chemical storage tanks have significant advantages of their own through the use of MDPE. Below are some of the key benefits of polyethylene Chemical storage tanks.

  • The seamless moulding associated with MDPE with no joints or welds helps to eliminate potential leak points in the tanks.
  • The smooth wall construction can help reduce tank maintenance requirements and also facilities ease of the tank inspection.
  • MDPE frequently has lower acquisition and whole life costs.
  • There is no risk of wicking, which is a key benefit compared to GRP alternatives. Wicking can potentially compromise the integrity of some alternative materials.
  • MDPE has reduced manufacturing lead times
  • It is easily recyclable.

Difference between HDPE, LLDPE and MDPE

The difference between High density polyethylene and Medium density polyethylene is simply the density. MDPE has a density range of between .926 & .940g/cm3, whilst HDPE has a density of anything over .941g/cm3. MDPE is less sensitive and also has a higher stress cracking resistance than HDPE.

LLDPE stands for Linear lower density Polyethylene. This polyolefin has a number of short branches, which is how it differs to normal LDPE. It is characterised by its higher tensile strength and higher impact and puncture resistance to LDPE.

Why choose a Medium Density Polyethylene Tank?

Carbon and stainless steel tanks have provided dependable and reliable chemical storage since the dawn of the industrial age. So in the 21st century why choose a next generation Medium Density Polyethylene chemical storage tank? 

Our tank experts have laid out some of the key reasons to choose an MDPE tank over a traditionally built tank.

  • The seamless, single piece construction of an MDPE tank has eliminated potential chemical attack points.
  • Our tanks now are lighter and easier to handle than the carbon and stainless-steel alternatives.
  • Generally lower acquisition and whole life costs, as well as shorter manufacturing lead times when you choose MDPE.
  • There are a wide range of chemical tank storage applications without the need for high cost, specialist coatings.
  • MDPE tanks from Carbery Tanks are completely corrosion resistant and guaranteed to never rot, rust or corrode.
  • External models also do not require painting or additional protection
