Recent advancements in polymer technology have led to the development and use of thermoplastic olefins for roof membranes.
Recent advancements in polymer technology have led to the development and use of these polymers for roof membranes. The thermoplastic polymers (polypropylene or polyethylene) are combined with flexibilizing comonomers (elastomeric polymer) in a reactor during the fusion of the polymers. This combination of polymers adds flexibility to the thermoplastics. The recently developed technology has allowed for additives to be integrated with the base polymers, such as ultraviolet stabilizers, pigments (coloring), and fire retardants, to provide the weathering characteristics required in a roof membrane.
