Why Victrex APTIV 2000 film quietly underpins lighter, tougher electronics

Victrex APTIV 2000 film is the sort of material you never see but instantly notice when it is missing - connectors run hotter, motors whine louder, insulation browns. Here the thin PEEK film slips between copper and steel, staying dimensionally calm where other plastics give up.

What APTIV 2000 is made for

APTIV 2000 is a semi-crystalline PEEK film that Victrex positions as a workhorse grade for electrical insulation, slot liners, flexible printed circuits and EMI shielding laminates in demanding environments. Official Victrex product information

The film keeps its mechanical strength up to roughly 260 °C continuous use, shrugs off oils and solvents, and tolerates repeated soldering or reflow profiles that would deform PET or PVC.

How it behaves in daily use

On the production floor, APTIV 2000 cuts and punches cleanly, without the crumbly edges many engineers know from brittle high-temperature films. Converters can thermoform and laminate it, creating tight, rattle-free wraps around busbars or motor windings.

In real products that means quieter e-motors, more compact stators, and connectors that maintain creepage distances even after years of thermal cycling. The beige film itself stays surprisingly neutral in smell and color, even close to hot copper.

Compared with classic polyimide

Many engineers instinctively reach for polyimide films for heat, but PEEK-based APTIV 2000 offers a different balance. Its lower moisture uptake improves dimensional stability and dielectric properties in humid environments compared with standard polyimide solutions. Victrex application note on flexible circuits

The trade-off is cost and slightly lower maximum continuous temperature versus top-end polyimide. For many EV and industrial drives, however, designers prefer the greater chemical resistance and fatigue strength of PEEK when coolant, oils and vibration combine.

Where designers see limits

APTIV 2000 is not magic. In very thick builds it becomes relatively stiff, so for sharp bends designers may still need thinner gauges or hybrid stacks with softer layers. Processing PEEK also demands higher temperatures than standard engineering plastics.

That means tool steels, heaters and chillers must be specified properly. For smaller converters used to PET, the jump in processing complexity and material price can feel sobering initially, even if lifetime performance is convincing.

Pricing, formats and availability

Victrex supplies APTIV 2000 in multiple thicknesses, typically from tens to a few hundred micrometres, on wide rolls for laminators and slitters in Europe, Asia and North America. Victrex electronics solutions overview

Pricing is clearly in the high-performance bracket and quoted individually, but many OEMs offset the higher film cost with part consolidation, reduced failure rates and the option to design smaller, lighter assemblies.

Why this matters for Victrex and investors

Films like APTIV 2000 sit at the sweet spot of Victrex's strategy to move from basic PEEK pellets toward more specialized forms and applications, especially in e-mobility, industrial drives and advanced electronics.
