Safe drinking water
Our EPDM rubber recipes are composed with a focus on minimizing the formation of biofilm and ensuring resistance to water treatment chemicals.
No contamination of drinking water
Organic substances such as medicinal paraffinic oils and waxes migrate from rubber compounds. They act as nutrients for microorganisms, which will then start forming biofilm. Therefore, AVK EPDM rubber recipes are composed with focus on minimising the formation of biofilm. The rubber will therefore not provide breeding ground for bacteria.
High resistance EPDM rubber
AVK Fusion Indonesia offers drinking water approved EPDM compounds are resistant to ozone and water treatment chemicals, and are of course taste, smell, and colour neutral. Chlorine and other chemicals are commonly used to clean new pipelines or disinfect old ones. Ozone and chlorine may also be added in low concentrations to make the water drinkable. Ozonation is used to reduce smell and taste or to reduce bacterial activity. The chemical reaction will also cause degradation of rubber materials, if not adequately formulated to encounter highly reactive chemicals such as ozone. AVK’s own compound EPDM is superior to any other material, including many other EPDM materials. The unique structure can withstand an extremely high concentration of ozone. After 200 hours of exposure in 200 pphm the properties of AVK’s EPDM have not changed, while both the SBR and NBR grade are suffering.
