- The general purpose plastics such as Styrene-ethylene / butylene-styrene (SEBS) (Thermoplastic elastomers)  are widely used for making remote control keyboards, cell phone covers, toys, Tooth brush handles,  Desktop / laptop keyboards, automobile seat covers etc.
- These article surface are constantly exposed to infectious droplets from cough, sneezes, speech produced  by infected persons.
- Similarly plastics such as polyurethane foams, PVC, Polypropylenes are 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 develops biofilm within hours. It is observed that these devices are not usually  cleaned properly, it's surface become a place for microbial growth, leading to spread of infections.
- Venus-ZP is an effective biocide which is able to 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 has fast inhibition results against the micro organisms 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.

Venus-ZP is classified as Hazardous substance. (UN 2811)
