Certificate of Analysis-COA 

 Applications 

1. Polymeric Hindered Amine Light Stabilizer: Light Stabilizer 944 is a high molecular weight polymeric HALS whose piperidinyl groups trap the free radicals formed when ultraviolet light and heat attack a polymer chain, interrupting the degradation cycle before it can cause chalking, cracking or loss of tensile strength.

2. Polyolefin Films And Tapes: A preferred choice for LDPE, LLDPE, HDPE, PP and EVA films used as agricultural greenhouse film, mulch film, silage wrap, packaging film and woven tape, where its high molecular weight keeps the stabilizer inside thin sections instead of evaporating during the blow film process or leaching out in service.

3. Fibers, Monofilament And Outdoor Textiles: Recommended for PP fibers, monofilament, multifilament, raffia, synthetic turf yarn, ropes, nets, tarpaulins and outdoor fabrics, delivering long term light stability in very thin cross sections where low molecular weight stabilizers are lost by volatilisation and surface migration.

4. Pipe, Cable And Construction Profiles: Suitable for HDPE and PP thick section articles such as water and gas pipe, cable and wire sheathing, geotextile, geomembrane and PVC window profile, where it protects against surface cracking and chalking under continuous outdoor exposure.

5. Engineering Plastics, Automotive And Synergy: Also performs in ABS, PS, SAN, PMMA, polyamide and elastomer systems, and can be combined with benzotriazole ultraviolet absorbers, phosphite or hindered phenolic antioxidants for a multi stage protection package covering automotive trim, appliance housings and outdoor equipment.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
