Thanks to the research and development department, PhotoACTIVE® technology has arrived directly to plastics and their main manufacturing and transformation process: the extrusion process.
PhotoACTIVE® Powder is designed to be inserted in the extrusion process and thus be part of the polymer that will make up the final plastic material.
The extrusion of plastic materials is a particular plastic deformation procedure, aimed at the production of constant section (“extruded”) pieces such as tubes, bars, profiles, plates, filaments for 3D printers, plastic films or simply granules composed of different materials and which are then used for other processes.
PhotoACTIVE® has a powerful antiviral, antibacterial and anti-mold action, managing to destroy the H1N1 influenza virus and the new coronavirus SARS-CoV-2 (COVID19).
The antiviral and antibacterial properties on treated materials have proven to be durable over time.
In the extrusion process, the plastic materials in the form of small granules are first fused together by heating at specific temperatures, then they are given a specific shape and finally, they are subjected to a cooling-consolidation process.
Through the plastic material extrusion process it is possible to work different materials such as rubber and the following thermoplastic materials:
- PVC (polyvinyl chloride)
- PE (polyethylene)
- PP (polypropylene)
- PA (polyamide)
- HDPE (high density polyethylene)
- LDPE (low density polyethylene)
- ABS (acrylonitrile butadiene styrene copolymer)
- PC (polycarbonate)
- SB (styrene butadiene)
- PMMA (polymethyl methacrylate)
- TPU (thermoplastic polyurethane)
- PEEK (polyether ether ketone)
- others (polystyrene, abs, nylon …) etc.
Each material is suitable for a specific use: thermoplastic materials are used, for example, in the production of filaments for 3D printers; this is a market which is taking on increasingly significant market volumes.
PhotoACTIVE® Powder is thus fully effective even when it is inserted directly into the process.
