What technical requirements define self adhering polymer modified bitumen sheet for asphalt or bitumen modification?
Self-adhering polymer modified bitumen sheets must meet specific technical requirements, including a minimum softening point of 100°C, a tensile strength of at least 1.5 MPa, and an elongation of 30% or more. The polymer content should be between 3-5% to ensure flexibility and adhesion. Additionally, the sheets should exhibit excellent resistance to UV radiation and thermal aging, with a low permeability to water. Compliance with ASTM or EN standards is also essential for quality assurance.
