From carbon fiber to Kevlar, ensuring consistency and quality with composite parts starts with proper compaction. At Dunstone, our high-temperature heat shrink tape applies compression optimally during cure cycles to reduce waste, streamline processes, and improve quality.

Our line of high-temperature heat shrink tape is the ideal alternative to other compaction films that don’t maintain compressive force as heat rises during curing. We offer a full range of heat shrink wrap tape products.

Maintains compression as resin viscosity drops

Uses 50-75% less material than other compaction films

Available in polyester, ETFE, polyimide, and silicone

Works in cure temperatures from 165ºC to 400ºC

Shrink percentages ranging from
5% to 20%

Can be produced incredibly thin — as little as 0.001”

Release coatings available — single- and double-sided

Can be hand-wound or applied via winding machine

Available with perforations for outgassing applications

Unlike non-shrink films that relax as temperatures rise during curing cycles, Dunstone Hi-Shrink Tapes begin to shrink at 70°C / 158ºF and reach maximum shrink force in the 120°C / 248ºF to 160°C / 320ºF range. This tailored compression curve ensures optimum compressive strength just as the resin in your layup begins to flow — helping you prevent voids and defects while maximizing lamination and surface finish.
