Uncalendered Aramid Paper Laminates
Uncalendered Aramid Paper Laminates
Flexible insulation for demanding applications
Brand: METALAM‑APA‑UC
Category: High‑Temperature Electrical Insulation Laminates (Class F)
Product Overview:
METALAM‑APA‑UC is Chirag Laminates' premium uncalendered aramid paper / polyesterfilm / uncalendered aramid paper laminate supplied uncalendered to preserve the natural porosity, compressibility and flexibility of the aramid facings. The open‑fibre structure guarantees excellent resin uptake during vacuum‑pressure impregnation (VPI) while the PET core provides mechanical stability. These attributes make METALAM‑APA‑UC the insulation of choice for traction motors, EV drives and dry‑type transformers operating continuously up to 155 °C.
Key Features:
-
Uncalendered aramid facings – maximum varnish or epoxy penetration; void‑free insulation
-
Class F thermal index – reliable in severe‑duty environments
-
High tear & burst strength – resists stresses during tight slot insertion
-
Excellent flexibility & crease resistance – ideal for automated insertion machines
-
Low shrinkage & warp – maintains accuracy after thermal cycling
-
Halogen‑ and silicone‑free – supports modern EHS requirements
Typical Applications:
-
Interwinding spacer paper in electric motors.
-
Layer, end‑filler and inter‑layer insulation in dry‑type / cast‑resin transformers
-
Bus‑bar wrapping and edge protection in UPS & renewable‑energy inverters
-
Thermal and dielectric barriers in battery modules and power‑electronics packs
-
High‑frequency reactors, chokes and generators demanding Class H reliability
Form Available:
-
Master rolls: 980 mm ± 10 mm width, OD ≈ 470 mm
-
Slit tapes: 6 mm – 600 mm widths on 3" or 1" ID cores
-
Sheets & die‑cuts: CNC/laser‑profiled slot liners, barriers spacers.Minimum order quantities can be tailored for prototyping or maintenance batches.
