We cast the TPU.We make the adhesive.We coat the film.

Three of the four layers in a paint protection film are made inside our own group. That is why niu can hold a colour match across a 353-shade book, and why a roll code can be traced back to the metre it came off.

The range

Six lines, one cast TPU base

Clear, matte, colour, pearl, glow and the specialty parts a full-body kit forgets. Every line starts on the same cast sheet, which is why a colour from the book and a clear film from the roll behave the same way under a squeegee.

How it is made

Four of the layers are ours

A paint protection film is four things stacked: a top coat, a TPU base, an adhesive and a liner. Most brands buy at least two of them. We buy the liner.

01
TPU base

Imported casting line. We cast our own aliphatic polycaprolactone TPU sheet rather than buying blown film, which is what keeps the optics flat and the thickness even.

02
Adhesive

A sister company in the same group formulates and produces the solvent acrylic adhesive. Adhesive is where a film quietly fails, so we do not buy it from a catalogue.

03
Coating

Two fully imported precision lines with micro-gravure, slot die and comma heads. The coating head sits in a Class 1,000 zone inside a Class 10,000 hall.

04
Curing and laminating

Cure, laminate the liner, then rest the roll. Resting matters: adhesive that is slit the same day it is coated behaves differently three months later.

05
Slitting

Slit to the width the order asks for, on the same site. Every roll carries a code that traces back to the coating run and the metre.

06
Inspection

110 instruments, from raw-material analysis to full inspection of finished rolls. Lab test, small batch, pilot run, then production.

The colour book

353 colours for Colour and Pearl PPF

Gloss, matte and special effects, grouped into twelve families. Every swatch is a real cast sample, not a printed chip — which is why the book and the roll match.

The plant

Two coating lines, 30,000 m of PPF a month

Class 10,000 hall, Class 1,000 at the coating head, and 110 instruments between the raw material and the finished roll.

Why buyers switch

The four questions we get asked first

Who actually makes the film?

Shanxi Xuanyuan New Materials coats it. niu is the brand it ships under to distributors. Xuanyuan sits inside the same group as Guangdong Xinrui New Materials and, above that, Shantou Dongfeng Printing — SSE 601515.

Can I get a sample before ordering?

Yes. Swatch books and sample rolls go out before a first order. Tell us the line and the market and we will send what is relevant rather than the whole book.

Do you do private label?

Yes — own brand, own carton, own roll-code prefix. Territory exclusivity is available against committed annual volume.

How long is the warranty?

Quoted per programme rather than printed on a page. It varies with the line, the UV load of the destination market, and installer certification.

Samples before a first order.

Tell us the line and the market. We send what is relevant rather than the whole book.
