More Information
Summary:The invention discloses a high-density polyethylene double-layer water supply pipe which comprises an inner layer and an outer layer, wherein the inner layer is mainly prepared from the following raw materials by weight: 70-88 kg of high-density polyethylene, 5-15 kg of a rigidity and toughness increasing additive, and 5-15 kg of a compatibilizer. High-density polyethylene and the additive are selected to be specifically proportioned, so that the prepared high-density polyethylene double-layer water supply pipe has higher toughness and rigidity at the same time.
