TPU Color Wrap Film is a 7.5 mil aliphatic thermoplastic polyurethane color-change film that carries its own paint protection layer. Unlike a printed vinyl wrap, the color is built into the top coat of a TPU body, so the same roll delivers a genuine color change, a heat-activated self-healing surface and impact absorption against stone chips. It is manufactured for the aftermarket, for wrap studios, distributors and fleet buyers who want one SKU to cover both the styling and the protection segments.

This page documents the construction, the measured performance values, the installation window and the warranty terms as they are applied in production. Where a figure is a typical value rather than a guaranteed limit, it is labelled as typical. Buyers can request the corresponding batch test report before shipment.

The film is built in four layers. A high-gloss colored top coat carries the visual finish and the self-healing chemistry. Beneath it sits an aliphatic TPU core that provides elongation, impact absorption and flexibility at low temperature. A repositionable acrylic adhesive with air release channels forms the bonding layer, and a 1.5 mil PET liner protects the adhesive until installation.

Two engineering decisions drive most of the performance. First, the base polymer is aliphatic rather than aromatic. Aromatic TPU is cheaper but its molecular structure absorbs UV energy and degrades into visible yellowing; an aliphatic chain resists that pathway, which is why light colors such as Pearl White and Iced Plum Pink can be offered with a five-year outdoor warranty. Second, the self-healing function is a property of the crosslinked top coat, not a sprayed additive. When the surface reaches approximately 40 degrees C, polymer chain mobility allows micro-scratches to close. The effect is repeatable, and it does not depend on a consumable that wears away after a few months.

• Self-healing top coat: Wash-brush marks, fingernail scuffs and light road-dust scratches close within about 30 seconds once the surface reaches roughly 40 degrees C from sunlight, warm water or a heat gun. Verified by repeated hot-water recovery testing on production batches, not a single-shot laboratory sample.
• Impact resistance: The TPU core absorbs stone chips and light parking contact on bumpers, hoods and door edges, spreading the load across the elastomer instead of transferring it into the paint. Recommended for high-mileage and highway use.
• High optical clarity and gloss: The clear top coat measures above 90 gloss units at 60 degrees by glossmeter, so metallic and pearl pigments stay crisp with strong distinctness of image rather than a milky, plastic look.
• True color change: A library of gloss finishes including Nardo Grey, Liquid Silver, Black Red, Pearl White, Iced Plum Pink and GT Silver allows a full-body transformation without a paint booth, masking or curing time.
• Non-yellowing aliphatic base: UV stability is designed into the polymer chain, keeping light colors visually consistent through years of vertical outdoor exposure.
• Installer-friendly handling: Air release channels let trapped air escape under the squeegee, and the repositionable adhesive allows lifting and re-laying on curved panels and mirror caps.
• Clean removal: Within the warranty period the adhesive releases from OEM paint without residue, protecting resale value for leasing and fleet customers.

Values marked typical are representative production figures, not minimum guaranteed limits on every roll. Batch-specific test reports are available on request.

Most warranty claims we see do not come from the film itself but from installation temperature and post-heating. In our application support work with wrap studios, three points decide the outcome. First, keep the ambient bay between 20 and 30 degrees C; below 15 degrees C the adhesive loses tack and the film becomes stiff on compound curves. Second, use a felt-edge squeegee at roughly 45 degrees with overlapping passes so the air release channels can vent before the adhesive wets out. Third, post-heat every edge and every recessed area to 60 to 70 degrees C and hold it there for a few seconds; edges that are only pressed, not heated, lift within a season.

For full-body work, plan the roll layout before cutting. A 1.52 m x 15 m roll covers a compact sedan or a mid-size SUV with careful nesting; large pickups and vans usually need the 17 m length. Allow the film to relax on the panel for a few minutes before final squeegeeing on horizontal surfaces, and never stretch a colored film more than about 25 percent on a deep recess, because excessive stretch thins the color layer and changes the shade.

Production runs under ISO 9001 process control, and the material is tested against REACH, RoHS and FDA requirements so that European and North American importers receive documentation suitable for customs clearance and retail compliance review. Every carton carries a batch code that links back to the coating run, the color batch and the retained sample, so a claim can be traced to a specific production window rather than handled as an anonymous roll.

Documentation available on request includes the batch certificate of analysis, the material safety data sheet, REACH and RoHS declarations, and the warranty certificate template for the end customer. The company holds TPU invention patents and independent intellectual property in its core material technology, and exports to more than 30,000 customers with 60 to 70 percent of output shipped outside China.

The film is specified for full-body color change on passenger cars, SUVs, pickups and commercial vans, and for partial work such as roofs, hoods, mirror caps, pillars and bumpers where a factory color cannot be ordered. Detail studios use it to refresh leased vehicles before return, dealers use it to move aged inventory without paint work, and fleet operators apply corporate colors across mixed models while keeping the original paint intact for resale.

Because it combines a color layer with genuine impact protection, it also fits buyers who would otherwise purchase a clear paint protection film and a separate vinyl color wrap. One application delivers both results, which reduces labour hours per vehicle and lowers the total cost of ownership.

The warranty covers delamination, blistering, cracking and yellowing beyond an agreed threshold for five years of vertical outdoor exposure, when the film is installed by a trained applicator following the published installation guidance and maintained with pH-neutral shampoo. It does not cover damage from collision, abrasion through misuse, automated brush washes with worn bristles, abrasive polishes, or removal and reinstallation of the same piece of film. Written terms are provided with every order so the buyer knows the boundary before the sale, not after a claim.

Each roll is wound on a hard paper core, wrapped in PE film and packed in an export carton with pallet loading for container shipment. Minimum order quantity is one roll, volume pricing runs from US$98 to US$115 per roll depending on color and thickness, and standard delivery is 7 to 15 days after deposit. OEM private-label printing on the liner and carton is available for distributors building their own brand, and technical support covers installation temperature, squeegee technique, post-heating and aftercare.
