Strong UV-A/UV-B absorption
Absorbs 300–400 nm, protecting polymer and contents.
SUNSORB®P (UV-P) is a benzotriazole UV absorber that strongly absorbs UV light between 300 y 400 Nuevo Méjico. It protects clear and light-colored PS, CLORURO DE POLIVINILO, PMMA, polyester and other plastics against yellowing.

UV-P (2-(2H-benzotriazol-2-ilo)-p-cresol) is a widely used benzotriazole UV absorber with low color. It is used in styrenics, CLORURO DE POLIVINILO, acrylics, poliéster, policarbonato, coatings and adhesives. Its relatively low molecular weight (225.2) suits thicker parts more than thin films processed at high temperature.
Typical specification. Every shipment is supplied with a batch COA; the limits that apply to your order are confirmed in the quotation and contract.

Protects clear styrenics and acrylics against yellowing; typically 0.1–0.5%.
Used in rigid and flexible PVC.
UV protection in polyester, coatings and adhesives.
25 kg net bags or cartons with a PE inner liner. Palletized; private-label packing on request.
Keep sealed in a cool, seco, ventilated place away from heat and direct sun. See the SDS for full handling details.
Typically 3–15 business days from order confirmation, depending on quantity. ENGAÑAR, CIF or DAP to major ports.
Indoor light behind glass, outdoor temperate climate and desert or tropical exposure need very different packages. Note the target service life and the weathering test you use (xenon or QUV, horas, ΔE or gloss retention).
A UV absorber works by filtering, so it needs enough path length: thick parts need less, thin films and fibers need more and need a low-volatility grade. Check the absorber survives your processing temperature.
For outdoor use the standard approach is UV absorber plus HALS. Send your current package and pigment system and we suggest a starting combination for the trial.
Some benzotriazoles are restricted in the EU and other markets. Tell us the destination and end use, and we confirm the REACH and food-contact position of the grade before you order.

Benzophenone UV absorber for polyolefins and PVC, cost-effective and widely used.
View product →Its low molecular weight makes it volatile at high processing temperatures. For thin films and fibers, higher-MW grades such as 234 o 360 are usually better.
0.1–0.5% depending on thickness and exposure, often with a HALS for outdoor use.
It has low inherent color and is used in clear products.
Sí. Tell us the polymer, the test you plan to run and the quantity you need. Samples ship with a COA so you can compare the lot against your current material.
Send us the agreed specification and the COA showing the difference (parameter, unit and test method). We check it with the production batch record before you accept the material, and replace or re-test where the lot is out of specification.
Send your application, specification and quantity to request a quotation or supporting documents.
