GARFLEX Pressphan Laminates

Brand: GARFLEX

Category: Electrical Insulation Laminates

Product Overview:

GARFLEX Pressphan Laminates are cellulose-based electrical-grade Pressphan bonded to polyester film with a high-temperature adhesive system. The kraft-cellulose facings deliver excellent oil absorption and mechanical rigidity, while the central PET core provides dimensional stability and tear resistance. Designed for Class A (105 °C) and Class E (120 °C) insulation systems, GARFLEX laminates are the trusted choice for power-equipment manufacturers that need cost-effective, eco-friendly insulation with proven dielectric reliability.

Key Features:

High oil absorption & impregnation affinity: Ensures void-free insulation in oil-immersed transformers and reactors
Excellent dielectric strength: Typically > 12 kV/mm across the laminate
Good mechanical rigidity & compressive strength: Keeps slot liners and spacers stable during winding and impregnation
Stable in transformer oil & ester fluids: No delamination, swelling or fibre shedding after long-term ageing
Customisable colour coding: Brown (Industrial grade) or Green (Commercial grade) for quick shop-floor identification
Halogen-free & recyclable: Meets modern sustainability requirements
