Protective filmTechnical advantages
Why HEWEI 2.0 Polyurethane (PU) Technology
Comfortability
HEWEI PU material has excellent flexibility and resilience, can perfectly fit the human body curve, and is not easy to deform after long-term use. It effectively relieves fatigue caused by long-term sitting and provides users with a comfortable sitting experience.
Long life
Ultra log life (Durable, 8 years of use, service life than PU/PVC leather-), due to advanced production from teh western RlM technology to finish by molding injection. Sponge core + 2mm leather on the surface is foamed in one piece.
Excellent stain resistance
The surface of the protective film has been specially treated to have good hydrophobicity and stain resistance. Stains are difficult to penetrate and adhere to. When cleaning, just wipe it lightly with a damp cloth to easily remove it, which greatly reduces the difficulty and frequency of cleaning and keeps the chair clean and tidy.
Unique formula
Whether it is a waiting area with high-intensity use or a laboratory with strict requirements on material stability, we can flexibly adjust the PU formula according to customer needs, accurately control the tension and density, and tailor-make chairs that fit the scene to achieve the best balance of durability, comfort and function.
Stable weather resistance
Whether in a dry indoor environment, or occasionally exposed to moisture or even under different temperature changes, Hewei polyurethane transparent protective film can maintain stable performance. It will not deform, discolor or lose viscosity due to environmental factors, will not become soft and fall off in high temperature environments, and will not become brittle and crack in low temperature environments, always providing reliable protection for the chair.
Advanced flame retardant technology
Adopting advanced CA117 flame retardant PU formula, whether it is a waiting area with dense personnel and high mobility, or a laboratory environment storing a large number of experimental equipment and chemical reagents, it can build a reliable safety line for users with its excellent flame retardant performance.

Polyurethane Production Process
01
Raw material preparation
In the PU raw material mixing process, we use high-precision metering equipment to strictly follow the exclusive formula to accurately control the amount of polyols, isocyanates and various additives. Advanced stirring technology is used to ensure that the raw materials are fully blended under specific temperature and time conditions. In this process, by accurately controlling the reaction rate and mixing uniformity, a PU prepolymer with stable performance is formed.
02
Low pressure casting technology
During the molding stage, we use advanced low-pressure casting technology to allow the mixed PU material to quickly and evenly fill the mold cavity and accurately shape the complex chair parts. This technology can effectively reduce the generation of bubbles inside the material and improve the density and structural strength of the product.
03
Casting
During the molding stage, we use advanced high-pressure casting technology. Using high pressure environment, the mixed PU material quickly and evenly fills the mold cavity to accurately shape the complex chair parts. This technology can effectively reduce the generation of bubbles inside the material and improve the density and structural strength of the product.
04
Demolding
After curing is complete, the chair is removed from the mold. The demoulding process requires careful operation to avoid damaging the surface or structure of the product. For some complex molds, we will use special release agents or demoulding equipment to ensure smooth demoulding.
05
Ripening
The foam after demolding is still in the active stage of chemical reaction and has not completed all aging reactions. It needs to undergo a strictly controlled 10-minute aging process in a constant temperature environment to ensure that the product material completes all molecular structure reorganization.
06
Inspection
The edge of the demolded product and the connection between the mold may produce irregular shapes. Use a blade to scrape off the irregular shapes of the product edge; manually inspect the product quality, qualified products enter the assembly process, and products that need to be repainted enter the assembly process after repainting. Foamed defective products are treated as general solid waste.
07
Repainting and curing
There will be color difference after the parting line of the product is trimmed (or there will be color difference if the paint is uneven during the production process). It is necessary to spray the mold with outer paint in the spray room for repair. After spraying, the paint is dried and cured in the oven.

Professional Certification
Our SGS Certifictions and Innovation Patents
SGS Certifictions
As the world's leading inspection, identification, testing and certification organization, SGS's certification is highly authoritative. After strict testing by SGS, the Polyurethane Clear Protective Film technology has excellent performance in antibacterial properties, wear resistance, temperature resistance, transparency retention and other aspects, which fully proves the reliability and advancement of the technology.
HEWEI polyurethane transparent protective film uses advanced polyurethane materials, which have a unique molecular structure and give the protective film many excellent properties. The high strength and flexibility of polyurethane materials enable it to effectively resist various external impacts. At the same time, it also has excellent wear resistance, which can maintain the integrity of the protective film for a long time and provide lasting protection for the protected objects.
Innovation Patents
The antibacterial polyurethane cushion material independently developed by Hewei Technology officially passed the national invention patent certification on August 28, 2018, and the patent number is CN104892893B. This invention patent certificate was issued by the State Intellectual Property Office of the People's Republic of China. It is not only a high recognition of the innovative wisdom of Hewei scientific research team, but also a strong proof of Hewei deep technical background in the field of material research and development. This patent achievement makes Hewei stand out in the cushion material market and establishes its leading position in technology.
The test results show that the cushion material has a significant inhibitory effect on common pathogens such as Klebsiella pneumoniae, Escherichia coli, and Staphylococcus aureus. It can be clearly seen from the comparative test chart that the growth of bacteria in the sample area containing antibacterial agents is effectively controlled, while the areas without antibacterial agents are multiplied by bacteria. This fully shows that the use of Hewei antibacterial polyurethane cushion materials can effectively reduce bacterial growth and provide users with a healthier and cleaner sitting experience.
