Four new grades of biocompounds enlarge the “green” portfolio of Sirmax

The product portfolio of Sirmax Group is increasingly “green”. In the sustainable development context towards which the company has been focusing since some years ago, the range of bio-compound products, with the brand Biocomp produced by the company group Microtec, based in Mellaredo di Pianiga (Venice, Italy), is expanding. The bioplastics portfolio has been enriched by four new grades - which add to the already existent ones - specifically developed for injection molding and extrusion/thermoforming: Biocomp IM 95, Biocomp IM 95CP, Biocomp IM DPLA and Biocomp IM CFLEX.


The new grades are based on the formulation of innovative plant materials with the inclusion of natural additives which ensure a content of renewable “biobased” sources up to 100% (referencing to ASTM D 6866). The main properties of the new grades are the ease of processing through extrusion and moulding, the limited cycle time, also using standard presses with non-dedicated screws for plasticisation, and the great resistance to deformation due to heat with HDT up to 95° C (without pre- or post-crystallization processes).


The four new grades introduced are suitable to produce “single use” products or “semi-durable” goods which are wholly biodegradable and compostable according to the EN 13432 norm, certified “OK Compost Iindustrial” by TUV-Austria. They can be used in several application fields: plates, glasses, cutlery, straws, clips for agriculture, pens, brushes, trays, jars, lids, coffee capsules, toys, closing caps, and more. In sight of the new and more stringent European regulations, the objective is to respond to the new needs of the market, especially those of the food market, identifying innovative solutions in the perspective of sustainability. All the Biocomp compounds, indeed, are suitable for the contact with food in accordance with UE norms.


“For Microtec these new products represent the entrance into a new field, the one of injection moulding. Now we are able to source our customers with the compound specific to thermoforming, too. We are already operative”, explained Diego Lombardo, Microtec managing director.
