Excellent Chemical Properties

• Transparent, resistant to heat, cold and moisture, with high mechanical strength.
• Translucent film made from plasticised, extruded polyvinyl butyral resin—with a smooth surface, defined roughness and good softness.
• Good adhesion to inorganic glass.

• Laminating room: 20–25°C, humidity ≤ 30%, dust-free; keep the machine clean.
• Wear uniform clothing, head covering and gloves to prevent dust, contamination and hair.
• Conditions: lamination at 20–30°C (max. 40°C).
• PVB at 20–25°C; check the PVB film and glass repeatedly for cleanliness and fit.

• Cold vacuuming: 20–25°C, pressure: −0.095 to −0.1 MPa; 2–15 minutes (continuous).
• Hot vacuuming: glass at 100–120°C; 30–45 minutes; pressure: −0.095 to −0.1 MPa; remove the glass as the temperature rises.

• Preheat the thermostat: lamination at 20–30°C, humidity 25%.
• 1. Temperature 100–120°C; first rolling; pressure 0.2–0.5 MPa; roller gap < 1 mm of glass thickness.
• 2. Temperature 160–180°C; third temperature 220–240°C; second rolling; pressure 0.3–0.5 MPa; roller gap < 2 mm.
• Maintain the thermostat temperature through continuous operation.

• Increase and reduce temperature and pressure slowly throughout the process (reference):
• 60°C / 0,4 MPa
• 90°C / 0,8 MPa
• 120–130°C / 1,1–1,13 MPa
• Hold for 30–60 minutes, depending on the glass thickness and quality in the autoclave.
• Hold stable at 90°C; vent after cooling to 45–55°C.
