HDPE material meets the latest environmental requirements
An important reason for the promotion and application of polyethylene is that polyvinyl chloride is increasingly under pressure from environmental protection. The first is the sanitary performance of polyvinyl chloride itself: as we all know, the sanitary performance of polyvinyl chloride pipes produced under formal production and strict control can be guaranteed and allowed to be used in the field of drinking water. However, there are still people who worry that problems may occur in places where the control is not strict: for example, the vinyl chloride monomer in the PVC resin exceeds the standard, and the toxic additives are misused in the formula of the PVC pipe for water supply.
Misuse of PVC pipes and pipe fittings for drainage, which are not guaranteed to be non-toxic, is used for water supply pipes and pipe fittings. The second is the recycling of polyvinyl chloride pipes: polyvinyl chloride, like polyethylene, is a thermoplastic and can be used theoretically, but various countries have proved that the proportion of old plastic products that can be recycled is limited, and the main treatment method is It is incineration to recover energy.
Polyvinyl chloride contains chlorine and may produce harmful substances if it is not well controlled during incineration, while polyethylene only contains hydrocarbons, which produce water and carbon dioxide after incineration.
