Product Description

Definition of TPO Waterproof Membrane Production Line

Haiming Machinery TPO and Internally Reinforced TPO Waterproof Membrane Production Line is a fully automatic system that processes TPO resin and auxiliary materials into finished membranes through extrusion, co-extrusion, reinforcement embedding, cooling and winding. It supports continuous production and adapts to different project requirements.

Main Application Fields

Industrial and commercial roofing systems
Photovoltaic roofing waterproofing
Basement and tunnel waterproofing
Infrastructure and water conservancy projects

Product Structure & Types

Available Membrane Types

Homogeneous TPO (Type H): Pure TPO extrusion, thickness 1.2–2.0mm
Internally Reinforced TPO (Type P/G): TPO + polyester/glass fiber mesh + TPO, thickness 1.5–2.0mm
Backing TPO (Type L): Bottom non-woven fabric for cold bonding

Reinforced Structure Advantage

Improves tear resistance and tensile strength
Enhances dimensional stability
Suitable for large-span and high-load roofing
