Max SCRIM Liner (LinerTube™ Reinforced)
Max SCRIM Liner is a non-woven, needle-punched polyester fiber felt offered with either PU or PVC coating. There is a 100% continuous polyester reinforcement filament (SCRIM) integrated into the fabric to limit longitudinal stretch during installation. Tube forming and seam bonding are achieved through a specially designed thermal welding and/or an overlocking chain stitched sewn process – creating a superior, high-performance impermeable liner designed for accuracy.
TECHNICAL DATA:
Coating: PU or PVC
Carrying Material: Polyester Felt with integrated SCRIM
Seam: Stitched or Thermal Welded with an extruded tape seam
Installation: Inversion
Recommended Curing Methods: Ambient, heat or LED light cure
Resin Compatibility: Use with MaxPox®, VertiPox® Epoxy
Resin Systems, MaxLight® UV LED Resin Systems, MaxPox® VE
(PVC only) or approved equal
DIAMETER RANGE:
3” and larger
THICKNESS RANGE:
3 mm and 4.5 mm
AVAILABLE MANUFACTURER LENGTHS:
164′ and 328′ stock lengths (+/-)
Custom transitions and longer lengths available.
APPLICATIONS:
• Open-End (Blindshot) with Calibration Tube
• Closed-End
Ideal for landing the liner at a definitive point and straight piping applications. This non-stretch liner may be used
on sweeping bends up to 45° with slight wrinkling. Manufactured transitional liners and custom sizes are
available.
INSTALLATION:
Installation Air Pressure: 8 to 10 psi (may need additional pressure to invert around bends).
Curing Pressure: 7 to 9 psi
Vacuum: -0.5 bar.
Vacuum level shall meet or slightly exceed Inversion and Curing Pressure. Always use a vacuum with proper
vacuum gauge and regulator.
Recommended Gap Setting: Thickness of liner x 2 + 2mm
Always use a guide tube to contain unsupported liners from radial expansion.
STORAGE/HANDLING:
Avoid extremes of temperature
• Freezing may cause the coating structure to degrade locally, especially areas where the coating is in
tension or compression – at bends and edges, and immediately adjacent to seam welds.
• Recommended storage temperature 40°F – 95°F.
• Shelf life at this temperature: in excess of 1 year.
Avoid extremes of humidity
• Very high relative humidity (especially at high temperature such as tropical countries) will accelerate the
degradation, consequently reducing the shelf life.
• Recommended storage humidity 25% rh – 65% rh.
• Shelf life at 65%, 95°F: 1 year.
Avoid prolonged wet storage
As with high humidity, the coating is more susceptible to degradation at higher temperatures, and even
further susceptible if pH of liquid in contact is significantly above or below 45°F. Wet storage is not
recommended.
Avoid direct sunlight
Prolonged exposure to the sun’s ultraviolet light will accelerate the degradation of the coating. Store away
from direct sunlight, preferably in dark conditions.
Mechanical damage should be avoided
• Ensure that liner is not placed directly onto grit or gravel floor – sweep and cover floor first.
• Ensure personnel are instructed not to walk on or smoke around the liner.
• Handle with care and ensure safe transport at all times.
• Ensure any rollers are clean, and the liner is not in contact with any sharp edges or snags anywhere during
use.
Chemical attack
Avoid prolonged contact with solvents and chemicals.
