UV Absorber UV-531

We are a professional manufacturer of UV absorbers, specializing in UV-531, UV-326, and UV-329 series UV absorbers. These absorbers efficiently absorb 270-400nm ultraviolet light and are suitable for PVC, PE, PP, coatings, textiles, and other industries. They professionally solve problems related to yellowing and aging in products, preventing yellowing, resisting aging, and extending product lifespan. They comply with RoHS/REACH environmental standards and offer free samples.

1.High-efficiency broadband absorption: As a high-quality ultraviolet absorber, it accurately covers the entire UVA/UVB band (270-400nm), with an ultraviolet absorption rate of >98%, blocking ultraviolet damage to the substrate from the source and effectively playing an anti-aging and anti-yellowing role.

2.High thermal stability: thermal weight loss temperature ≥350℃, suitable for high-temperature processing processes such as plastic extrusion, injection molding, and coating baking. It does not decompose, volatilize, or lose during processing, ensuring the stable protective effect of the UV absorber.

3.Low migration and anti-precipitation: Utilizing a high molecular weight optimized design, it is not easy to migrate to the surface of the product after addition, avoiding problems such as blooming, whitening, and precipitation, keeping the product appearance clean and improving the quality of the product.

4.Excellent compatibility: It has excellent compatibility with various plastics such as PVC, PE, PP, PS, PC, ABS, and PU, as well as coating resins and textile fibers. It disperses evenly without agglomeration and does not affect the original transparency, color and mechanical properties of the substrate.

5.Long-lasting protection: Resistant to extraction and weathering, with a protective performance degradation of less than 5% after more than 5 years of outdoor use, effectively extending the service life of products by 3-5 times and reducing customer replacement costs.

6.Highly processable: It is easy to disperse and does not affect the processing flowability of the substrate. It is compatible with various processing techniques such as extrusion, injection molding, blown film, coating, and spinning. It can be used directly without adjusting the existing production formula.

1.Plastics processing: covering PVC products (PVC foamed sheets, wood-plastic composite WPC, door and window profiles, pipes, decorative materials), polyolefins (PE/PP agricultural films, outdoor furniture, plastic pallets, automotive interiors), engineering plastics (PC/ABS/PA electronic casings, automotive parts, transparent sheets), and other plastics (PS, PU, ​​EVA toys, shoe materials, insulation materials), with a core focus on solving problems such as yellowing, embrittlement, and aging of plastics.

2.Coatings and inks: including architectural coatings (exterior wall paint, wood paint, roofing paint), industrial coatings (automotive paint, powder coating, anti-corrosion coating, coil coating), inks and adhesives (outdoor advertising inks, packaging adhesives, label inks), preventing coatings/inks from losing gloss, fading, and chalking, and improving weather resistance and decorative life.

3.Textile and fiber industry: Suitable for functional fabrics such as outdoor clothing, sunshade fabrics, tent fabrics, and curtains, as well as synthetic fibers such as polyester, nylon, and polypropylene, to improve the sun protection performance of fabrics, maintain color fastness, and inhibit fiber aging and yellowing.

1. Outdoor plastic products: such as PVC foam boards, wood-plastic composite flooring, outdoor furniture, and agricultural films, effectively resist yellowing, embrittlement, and cracking caused by sun exposure, extend outdoor service life, and reduce maintenance and replacement costs.

2. Architectural and industrial coatings: Exterior wall paints, automotive paints, etc., to prevent fading, chalking, and peeling of coatings when exposed to the outdoors for a long time, to maintain the bright color of the coating, and to improve the weather resistance and decorative durability of the coating.

3. Transparent products: PC transparent sheets, PET packaging, and acrylic products provide high-efficiency UV protection without affecting the transparency of the products, thus balancing protection and aesthetics.

4. Export-oriented products: Adapt to global environmental standards, helping customers' products pass RoHS, REACH and other certifications, and successfully export to markets in Europe, America and Southeast Asia, thereby enhancing the international competitiveness of their products.

5. High-value products: Electronic casings, automotive interiors, high-end packaging, etc., through long-lasting anti-aging protection, improve product quality and added value, and enhance the market competitiveness of customers' products.

- Packaging Specifications: Standard packaging is 25kg/cardboard drum (lined with PE plastic bag), moisture-proof, leak-proof, and pollution-proof; smaller packaging such as 1kg/bag, 5kg/bag, and 10kg/bag can be customized according to customer needs to suit small-batch sampling and production requirements. OEM/ODM customization is supported.

- Storage Conditions: Store in a cool, dry, and ventilated warehouse, avoiding direct sunlight, high temperatures (storage temperature ≤35℃), humidity, and rain; keep away from fire sources and oxidants to prevent product from becoming damp, clumping, and performance degradation; do not store with toxic or harmful substances.

- Shelf Life: Unopened and under suitable storage conditions, the shelf life is 24 months; after opening, please use as soon as possible to avoid prolonged exposure to air, which may affect product performance.

- Transportation Requirements: Transport as ordinary chemical products, avoiding heavy pressure, impact, and damage, ensuring the packaging remains intact; during transportation, keep away from high temperatures and open flames, protect from rain and moisture, and ensure safe delivery of the product.

With "quality as the foundation, customers as the core, innovation as the driving force, and compliance as the bottom line," we focus on the research and development and production of ultraviolet absorbers, adhere to the spirit of craftsmanship, and create cost-effective, environmentally friendly and compliant anti-aging solutions to help customers improve product quality, expand markets, and achieve mutual benefit and long-term development.
