Step-by-step Process (For Membran Kedap Air Berperekat Sendiri dari PVC):
- Raw Material Formulation: 100% virgin PVC resin blended with plasticizer, stabilizer, and anti-UV additives
- Mixing & Pre-processing: Automated mixing under ISO 9001 protocols
- Sheet Extrusion & Calendering: Thermoplastic extrusion, then stretching/calendering to specified thickness (1.2–3.0 mm)
- Self-Adhesive Layer Lamination: Advanced hot-melt glue or modified bitumen coating, ensuring optimal self-sealing
- Release Liner Application: HDPE or PET liner prevents pre-application sticking
- Cutting & Rewinding: CNC precision cutting for custom widths/lengths (commonly 1m x 20m rolls)
- Quality Inspection & Packaging: Tensile, elongation, hydrostatic, and UV-resistance tests – fully compliant with ISO 9001:2015 & EN 13967
Key Detection Standards: ASTM D638, ISO 527, GB 12953, ANSI/SPRI FM4435, and EN 1928 for watertightness.
