Mould release additives

The Einar^® product portfolio offers bio-based and food-grade solutions for mould release applications, tailored to meet the individual demands of PP, PE, PVC and PC injection moulding and PP compression moulding methods.

Bio-based mould-release additives for optimised processing and handling

Einar^® mould release additives are ideally suited for all food packaging applications and a range of other uses where precautions are required with respect to migration of additives from the packaging material to packaged goods.

Regardless of the end application, moulded pieces will benefit from an added release functionality which can be achieved with a series of different additives within the Einar® product line.

Thanks to our application centre in Denmark, we can help you test the performance of our Einar® products and compare them to your current additives. In this way you can see just how they can match or improve the quality of your products.

Why you'll need an efficient mould release agent

An efficient mould release agent will guarantee smooth release of parts in an injection moulding process and secure consistent operation and a reduction of cycle times. A mould release agent will lubricate the interface between polymer and mould during each injection moulding cycle and it is therefore of vital importance that the additive can be dosed at an optimum concentration where there is enough of a lubricant effect for efficient release but not too much to leave deposits or residue that may result in defective parts or clocking of the moulds venting system.

Semi-crystalline polymers such as polypropylene and polyethylene will exhibit some shrinkage when the resin solidifies and the effect of shrinkage will often require mould release additives for lubrication and efficient release of moulded parts. Shrinkage may also cause nesting problems of stacked parts and a secondary effect of an efficient mould release additive is to have good denesting properties that allows stacked parts to be easily separated.
