BUILT FOR SEAT ASSEMBLY

From the foam mold to the finished trim.

ELCRO develops automotive hook-and-loop components around the complete seat-assembly process. The backing integrates with expanding PU foam while the hook face creates a repeatable connection to loop material sewn into the seat cover.

Reliable performance

Automotive material construction engineered for secure foam integration.

Consistent attachment

Controlled dimensions and repeatable engagement for trim-cover assembly.

Custom geometry

Straight, curved and die-cut formats developed from customer drawings.

How it works

01Position in mold
02Inject PU foam
03Cure & integrate
04Attach trim loop

PRODUCT PLATFORM

Fastening components engineered around the seat.

Standard constructions and custom converting options support cushion, seat-back and trim applications.

ENGINEERING EVIDENCE

Designed to become part of the foam.

ELCRO’s rear structure gives expanding foam more area to penetrate and anchor. Internal comparison images indicate deeper integration and reduced incomplete formation around the fastening channel.
