Thermoforming Guidelines for KYDEX® 2210LT TB 143B

GENERAL GUIDELINES

• Do not utilize a flash heat forming technique as the process does not allow sufficient soak time for heat to reach the core of the material. The core sheet temperature should be within 5.6°C (10°F) of the surface temperature.
• Ideal heating cycle should be 1.0 – 1.5 seconds per 0.025mm (0.001”) thickness. KYDEX® 2210LT does not form like other KYDEX® sheet products; do not expect the sheet to ‘rebound’ at
• the end of the forming cycle once most stresses have been removed.
• KYDEX® 2210LT does not form like other polycarbonate-based sheet products; the sag will generally be less than other polycarbonate sheets due to its higher melt strength.

FORMING PARAMETERS

• Typical heater settings are 30 – 50% top heaters (primary sheet side) and 50 – 70% bottom heaters (secondary sheet side).
• KYDEX® Two-sided (sandwich) heaters are recommended for forming 2210LT and may be necessary for thicknesses above 2.03mm (0.080”).
• Base forming cycle on sheet temperature rather than a fixed cycle time.
• KYDEX® The forming temperature of 2210LT will range from 171 – 210°C (340 – 410°F) depending on the thickness of sheet, the complexity of the part, and the depth of draw.

• Forming temperatures should not exceed 215°C (419°F).
• Mold temperature should be set at 71.1 – 76.7°C (160 – 170°F) to prevent chill marks.

DRYING CONDITIONS

• Always pre-dry KYDEX® 2210LT before forming to avoid issues caused by moisture.
