no id's........ Fungus Resistance When rubber is used in any warm, damp environment, its properties must resist attack by mould or fungus. Although Silastic® silicone rubber is not antifungicidal, it is not a nutrient for fungi nor is it adversely affected by fungus or mould. With test procedures described in 005272B (USAF), several classes of Military Specification MIL-E, Silastic® silicone rubber was exposed to chaetominum, globum, aspergillus niger, aspergillus terreus, penicillium lutem, and fusarium moniliforne. None of these micro-organisms deteriorated the specimens. In another test, Silastic® silicone rubber samples were buried in 5 inches of warm (28 °C) moist soil for 6 weeks with no evidence of microbial attack. In a third test, samples were sprayed with a mixed spore suspension of fungi and then placed in a tropical test chamber at 27 °C, 90/100 percent relative humidity. None was attacked by mildew. http://www.dowcorning.com/content/rubber/rubberprop/weather_fungus.asp
