JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Daimaster is a masterbatch compound that contains 40% polypropylene and 60% natural fibre (hemp). It has to be mixed with pure polypropylene during the injection/extrusion process to reach 20-60% natural fibre content in the final part. Optimum performance levels can be achieved with 30% natural fibre content for injection and 60% for extrusion.

As an example, 50% Daimaster can be mixed with 50% polypropylene on the injection press to get a part containing 30% natural fibre. The natural fibre content and polypropylene type can be balanced to match the required specifications, and at the same time optimize cost and technical performance.

Daimaster + DaiflexFlexural applications
Daifa manufactures and/or supplies three standard masterbatches and four pure polypropylene materials intended for impact and flexural applications, using natural hemp fibre and polypropylene from TP and LB. This approach makes it possible to control sourcing and performance levels.
Customized or specific masterbatches can also be manufactured based on individual customer specifications, using other types of natural fibres such as wood, kenaf, jute, or sisal, and various plastic resins, including polypropylene, polyethylene, and PVC.
Using natural fibre instead of glass fibre in Daimaster brings the following benefits:
Located in eastern France, the Daifa group is a consortium of businesses working in the purchase, development, production, processing and marketing of plastics and plant-based raw materials for automotive processors and for the energy sector:
- plant-based raw materials: bales, fibres, pellets, powders, nonwoven mats, fabrics, and sandwich materials;
- plant-fibre-reinforced plastics: pellets, compounds, sheets, plates, sandwich and coated materials, thermosets and thermoplastics;
- renewable energies: biofuels and biomass power & cogeneration plants;
- project management, consulting and expertise: plant-based raw materials, automotive plastics processing, biomass plants.
Using this masterbatch compound requires adequate process specifications and only minor adaptations:
