PVC material is flame retardant (flame retardant value above 40), high chemical resistance (resistant to concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid and 20% sodium hydroxide), mechanical strength. And the advantages of good electrical insulation. With some chemical additives, making PVC material be of anti-UV, anti-mildew, anti-frost, anti-statistic, anti-bacterial, higher level frame retardant performance. And for health consideration, we can also make it meet RoHS, REACH, EN71-3 standards.
