TPO/EVA/HDPE polymer sheet Project
TPO / EVA / HDPE polymer sheet Project Scenarios Introduction:
The TPO/EVA/HDPE polymer waterproof and anti-seepage membranes produced by this intelligent extrusion line are widely used in global construction, environmental protection, agriculture, water conservancy and industrial infrastructure projects, covering the following core scenarios:
• Construction Waterproofing: Factory building roofs, commercial building rooftops, villa roofs, basement waterproofing, kitchen and bathroom anti-leakage projects
• Municipal & Environmental Protection: Landfill anti-seepage lining, sewage treatment tank anti-corrosion and anti-seepage, river slope protection, artificial lake impermeable engineering
• Agriculture & Water Conservancy: Fish and shrimp aquaculture pond anti-leakage, reservoir dam anti-seepage, garden landscape waterproof and moisture-proof projects
• Industrial Infrastructure: Chemical workshop anti-corrosion lining, tailing pond impermeable layer, tunnel and subway underground waterproof engineering
Introduction of TPO/EVA/HDPE polymer sheet:
The integrated intelligent polymer extrusion production line is independently developed for the global waterproof building materials industry. It is compatible with three mainstream polymer raw materials, including TPO, EVA and HDPE, enabling continuous and mass production of single-layer waterproof sheets and reinforced multi-layer composite geomembranes with stable and reliable output.
Equipped with a high-precision extrusion system, independent partition constant temperature control system, online real-time thickness detection device and frequency conversion speed regulation system, this equipment thoroughly solves the common defects of traditional extrusion lines, such as single material adaptability, low dimensional precision, high energy consumption and unstable finished product quality. The produced polymer waterproof membranes are widely applied in building roof waterproofing, underground engineering anti-seepage, landfill lining, river course renovation and aquaculture pond anti-leakage projects.
Adopting a modular integral frame structure and matched with customized flat die head and circulating cooling system, the production line supports flexible adjustment of membrane thickness, effective forming width and composite structure. It can process both virgin plastic raw materials and recycled mixed materials, featuring strong versatility, stable continuous operation and high cost performance. All equipment has passed CE international safety certification and ISO quality management system certification, fully complying with international manufacturing standards for waterproof materials and meeting the procurement and use requirements of global customers.
Technical Parameter of TPO/EVA/HDPE polymer sheet：
