Moulder Spotlight Series
The Spotlight Series will be a program of short videos and interviews with different moulders selected by Alkatuff.
Rotational Moulding Colouring P.3
The benefits and risks of pigments in rotational moulding have already been assessed in previous blog posts; Colouring P1 and Colouring P2, and this blog posts will look at how to incorporate it [...]
Rotational Moulding Colouring P.2
Pigments may not always be completely suitable for rotational moulding and many factors need to be taken into consideration: the environment, contamination of food and water, shrinkage and [...]
Rotational Moulding Colouring P.1
The colouring of poly water tanks also plays a huge role when deciding which grade to buy due to aesthetics and UV radiation as an impact on the polyethylene. Pigments play a major role in many [...]
Thermal Stability P.2
Antioxidants are necessary to provide protection to polyethylene over a number of stages. The first is during extrusion conducted by the polyethylene manufacturer. The second, for coloured [...]
Thermal Stability P.1
It is important that polyethylene resin has a broad processing window as it will melt and adhere to the mould easily, and it makes it less prone to oxidation, discolouration and loss of toughness [...]
Weather Resistance
Weather resistance can greatly affect a poly tank, as they can deteriorate quickly, especially when left outside.When polyethylene is exposed outdoors, the ultra-violet component of the sunlight [...]
Effect of Comonomer on Crack Resistance
Another factor to consider in deciding on a grade for rotational moulding of water tanks is the effect of comoner on crack resistance as the most important function of a polytank is containment! [...]
Effect of Melt Flow Index and Density
Choosing the right grade of LLDPEs depends on many factors, one of those being the effects of the melt flow index and density of the product which will be explored in this blog post.
Grade Selection for Rotational Moulding
Rotational moulding is a means of producing polyethylene articles of a size and shape that cannot be manufactured economically in any other way, and they are especially useful for poly tanks. [...]
