📩 International Inquiry for UV Absorbers – From Mario Alejandro

We recently received an inquiry from Mr. Mario Alejandro, requesting:

• 1000 kg of UV-327

• 800 kg of UV-P

• FOB shipping terms

We sincerely appreciate your interest in our UV absorber products and your trust in Ecochem as your polymer additive supplier.

However, before preparing the final quotation, we would like to share an important regulatory update regarding UV-327.

❗ Important Notice: UV-327 Has Been Discontinued Globally

UV-327 (CAS: 3864-99-1) was widely used as a benzotriazole-type UV absorber in plastics, coatings, adhesives, and synthetic fibers.
However, UV-327 has been fully discontinued, and manufacturers worldwide have stopped production.

Why is UV-327 no longer available?

• It has been banned in the EU and Switzerland due to environmental and health-related regulatory assessments.

• Global manufacturers have terminated production, making it impossible to source new material.

• As a responsible supplier following global chemical compliance, Ecochem does not supply UV-327.

Because many customers previously used UV-327 in various applications, we encourage purchasers to share their polymer system and application details so we can provide a suitable replacement.

🔍 Looking for a UV-327 Alternative? Tell Us Your Application.

Although UV-327 is discontinued, Ecochem offers a broad range of UV absorbers and light stabilizers that can effectively replace UV-327 depending on the polymer and application.

To recommend the best substitute, please share:

• What polymer are you using?
  (PP, PE, PVC, PET, PA, PC, PMMA, PU, ABS, coatings, adhesives, etc.)

• Indoor or outdoor application?

• Processing temperature?

• Required weatherability?

• Appearance or color stability requirements?

These details help us match your needs with the most effective UV absorber or light stabilizer.

Common UV-327 Replacement Options:

• UV-328

• UV-329

• UV-326

• UV-P

• UV-3039

• HALS Light Stabilizers: 770, 944, 783, 622, 292

We support technical evaluation, formulation optimization, and customized additive solutions.

🌞 Product Highlight: UV-P (2-(2′-Hydroxy-5′-methylphenyl)benzotriazole)

While UV-327 is no longer available, UV-P remains one of the most widely used UV absorbers in plastics and coatings.

General Information

• CAS: 2440-22-4

• Light yellow powder

• High thermal stability

• Strong absorption from 270–340 nm

• Excellent compatibility with multiple polymers

Applications of UV-P

UV-P is a versatile UV absorber suitable for:

• Engineering plastics (PA, PC, POM, PMMA)

• General thermoplastics (PP, PE, ABS, PVC)

• Coatings and adhesives

• Automotive plastic parts

• Optical-grade polymers

• Packaging materials

• Outdoor products exposed to UV radiation

• Fibers, films, and injection-molded parts

UV-P enhances UV resistance, prevents yellowing, and extends the durability of plastic products.

Ecochem provides stable quality UV-P with reliable supply and competitive pricing.

🌍 Applications: Why UV Absorbers Are Essential in the Polymer Industry

UV absorbers and stabilizers are crucial to protecting polymers from sunlight and ultraviolet degradation.

Main Functions

• Prevent polymer chain scission and oxidation

• Reduce yellowing and discoloration

• Maintain mechanical strength

• Improve weathering performance

• Extend the service life of plastic products

Industries and Products Using UV Absorbers
