When incorporated into a polymer, the coffee produces a natural, dark brown colour with a dark speckled effect. Colloids can optimise formulations to mask or enhance this effect, with the addition of pigments, to suit your design specification. When processed our compounds will produce a subtle coffee aroma.
Our compounds are recommended for injection moulding applications, flexible and rigid packaging, such as caps & closures, trays, POS and consumer household items etc.
The resultant environmental impact is that millions of tonnes of eggshell waste are being sent to landfill each year, causing a huge environmental affect. Eggshells primarily consist of calcium carbonate, making it a great alternative for chalk and therefore reducing the need for mining.
Colloids can incorporate powdered eggshell at concentrations from 10-50% (by weight) into various polymers.
The inclusion of eggshell powder gives a light speckled effect to the finished product. The eggshell compound can be used in a range of polymers with a wide choice of colours to mask or enhance the unique effect.
The EnviroTec eggshell compounds are compatible with L-TEC® laser technology to give a permanent mark, replacing the use of adhesive labels ensuring recycling compatibility.
