Bio plastics are a large family of different materials, not just one material. They consist of a whole family of materials with different properties and applications. According to European Bioplastics, plastic materials are defined as bioplastics if they are bio-based, biodegradable or both.

HME offers many advantages over other pharmaceutical processing techniques. Molten polymers during the extrusion process can function as thermal binders and act as drug depots and/or drug release retardants upon cooling and solidification. Solvents and water are not necessary thereby reducing the number of processing steps and eliminating time-consuming drying steps. A matrix can be massed into a larger unit independent of compression properties. The intense mixing and agitation imposed by the rotating screw cause de-aggregation of suspended particles in the molten polymer resulting in a more uniform dispersion. The process is thus continuous and efficient.

Biodegradable Compounds:

With extensive experience in the plastic compounding industry, together with broadly based Xinda process expertise in compounding, make Xinda a pioneer in the biodegradable plastics industry.

Xinda twin-screw extruder adopts modular design, and its main advantage is multi-functional configuration.Processing tasks can be optimally accomplished with only a few barrel and screw variations. We will make the detailed solution according to your specific application for Bio-degradable products.

Xinda Twin-screw extrusion lines offer major advantages for manufacturing biodegradable compounds:

 process flexibility, reduced downtime between batches and simple product changeover.

>   dedicated screw profiles for homogenous mixing quality.

>   Moderate shear and low shear stress without destroying delicate fillers.

>   Using high-accuracy gravimetric feeders to introduce the raw materials into the twin screw extruder, which can reliably feed biomas with poor liquidity such as starch.
