- The general purpose of plastics such as Styrene-ethylene / butylene-styrene (SEBS) (Thermoplastic elastomers) is widely used for making remote control keyboards, cell phone covers, toys, teeth brush handles, desktop / laptop keyboards, automobile seat covers etc.
- These article surfaces are constantly exposed to infectious droplets from cough, sneezes, speech produced by infected persons.
- Similarly, plastics such as polyurethane foams, PVC, Polypropylenes, widely used by human are constantly under threat to the infectious contamination.
- The World Health Organization has disclosed that the most common route for the transmission of diseases is by contact with surfaces contaminated with infectious droplets from coughs, sneezes or speech produced by contaminated persons; that can remain on surfaces for days.
- These infected surfaces develop biofilm within hours. It is observed that these devices are not usually cleaned properly, so the surface becomes a place for microbial growth, leading to spread of infections.
- Venus-ZP is an effective biocide which can migrate to the polymer surface, and inhibit the susceptible surface-colonizing cells, and hence delay biofilm accumulation. It is antimicrobial additive which has shown efficacy and fast results toward a large range of microorganisms, such as Candida albicans, Escherichia coli, Pseudomonas aeruginosa Salmonella choleraesuis and Staphylococcus aureus.
- The biocide action of Venus-ZP relies on the inhibition of membrane transport and efflux pumps of microorganisms taunting the accumulation of toxic substances inside the cells.
- The active ingredients of Venus-ZP have fast inhibition results against the microorganisms such as Candida albicans, Escherichia coli, Pseudomonas aeruginosa, Salmonella choleraesuis, Staphylococcus aureus etc.
- Antifungal action was evaluated against Aspergillus niger, Candida albicans and Cladosporium cladosporioides.  Venus-ZP eliminated 99.9% of the E. coli and 99.7 % of the S. aureus population and presented an inhibition zone in the fungal assay.
- The method involves dispersing Venus-ZP uniformly throughout the plastic for example, by compound extrusion processing of such plastics when in a fluid state.
- Concentration of Venus-ZP - 1 to 6% (Depending on the polymer and application)
- Venus-ZP used by co-rotating double screw extruder with a temperature profile ranging from 170°C to 190°C, speed of 300 rpm and melt discharge temperature of 200°C. It is also used by injection molding machine at 190°C and an injection pressure of 17 bars.
