New Generation of Environmentally Friendly UV Absorbers — JADEWIN UV 3638

In the current development of materials science, UV absorbers play a crucial role in effectively protecting materials from UV damage and extending their service life. JADEWIN UV 3638, as a new generation of environmentally friendly UV absorber, demonstrates unique advantages in numerous fields due to its outstanding performance characteristics.

1. Strong UV Absorption Capacity

JADEWIN UV 3638 exhibits highly efficient absorption of UVB and UVC, capable of absorbing UV light in the 280–400 nm range, with an absorption peak at 349 nm, covering the UVA, UVB, and UVC spectrums. Its absorption efficiency is several times that of ordinary UV absorbers, providing comprehensive UV protection for materials. It effectively blocks or absorbs UV energy, quenches singlet oxygen, reduces the likelihood of photochemical reactions, and prevents or delays the photoaging process of materials.

2. Unique Performance Advantages

(1) High Molecular Weight and Low Volatility

This absorber has a high molecular weight, resulting in extremely low volatility. During material processing and use, it does not easily lose its effectiveness due to volatility, enabling it to consistently provide UV absorption over the long term and ensure protective performance under various environmental conditions.

(2) Colorless and Non-staining

JADEWIN UV 3638 is colorless and does not stain, having virtually no impact on the color of the base material. This property makes it particularly suitable for the optical industry, which has extremely high requirements for light transmittance and color. For example, in the production of PET, PC optical material lenses, and light-diffusing plates for backlit liquid crystal display devices, using JADEWIN UV 3638 ensures excellent UV absorption performance while causing no adverse effects on optical performance or appearance color, thereby guaranteeing high-quality and high-definition products.

(3) Excellent thermal stability

It exhibits outstanding thermal stability, with a TGA (10%) exceeding 371°C. This means that under high-temperature conditions, JADEWIN UV 3638 remains stable, without decomposition or degradation. Therefore, it is particularly suitable for applications requiring high processing temperatures and strict UV absorption performance, such as thermoplastic polyesters, nylon, and the defense industry. In these industries, materials often require processing and molding under high-temperature conditions. The high thermal stability of JADEWIN UV 3638 enables it to adapt to such processing environments, providing continuous and effective UV protection for materials during high-temperature processing and subsequent use.

(4) High compatibility with PET materials

It exhibits high compatibility with PET materials and does not participate in the polymerization reaction during PET polyester synthesis. This characteristic allows JADEWIN UV 3638 to uniformly disperse within the PET material system, fully leveraging its UV absorption functionality while avoiding interference with the polymerization reaction and original properties of PET materials, thereby ensuring the quality stability and performance reliability of PET material products.

(5) Resistance to various environmental factors

In addition to high-temperature resistance, JADEWIN UV 3638 also exhibits resistance to high pressure and acid-alkali environments. This enables it to maintain stable performance under complex environmental conditions, such as high-pressure environments or acid-alkali corrosive environments, continuously providing reliable UV protection for materials. This significantly expands its application scope, making it suitable for protecting materials used in more harsh environmental conditions.

(6) Low addition rate and stable performance

In practical applications, JADEWIN UV 3638 achieves optimal UV absorption effects with only a small addition rate. During material processing and storage, it does not decompose, leach out, or migrate. This not only reduces usage costs but also ensures the stability and durability of UV absorption performance during long-term use and storage, guaranteeing that materials are consistently protected from UV radiation.
