Powerful R&D strength
As a National High-tech Enterprise, SUNPH holds 18 IP rights — including 9 invention patents, multiple utility models and software copyrights. We master cross-linked self-healing coating technology, have registered 1 Hubei provincial S&T achievement, and have 5 pending invention patents in smart-tinting and super-hydrophobic coatings, covering PPF, home films, specialty coatings and production control across the full technology chain.
Backed by a 20M m²/yr full-chain line, we use aliphatic TPU pellets from Merya and Covestro, produce in Class-1000 cleanrooms, and deliver mainstream products with tensile strength ≥27 MPa, elongation at break ≥260%, UV yellowing resistance ≥Grade 4, operating range ‑40℃ to 120℃, low-residue adhesive and defect rate PPM ≤3000 — suitable for all Chinese climates across automotive films, architectural window films and home protection films.
Our polymer materials R&D team brings together specialists in materials science, polymer chemistry, surface engineering and optical design, with core members averaging 10+ years of industry experience. We cover the full process chain from pellet modification and cast film to precision coating, supported by a complete material testing laboratory. Through industry-university-research partnerships with Wuhan Textile Univ. and Xi'an Aerospace Research Institute, we enforce incoming material and finished-batch verification under ISO9001 and IATF16949 certification — delivering integrated formulation R&D, performance testing and scale-up production.
