Drop-In Replacement For Cyasorb UV-3638F In High-Shear PET Extrusion

Technical Specs: TGA 10% Mass Loss Thresholds Above 370°C and Sub-0.5% Volatile Limits for Die-Line Prevention in High-Shear Extrusion

Chemical Structure of UV Absorber 3638 (CAS: 18600-59-4) for Drop-In Replacement For Cyasorb Uv-3638F In High-Shear Pet ExtrusionWhen evaluating a Benzoxazinone UV absorber for continuous extrusion lines, thermal degradation profiles dictate process stability. Our engineering data confirms that the 2,2-(1,4-Phenylene)bis(4H-3,1-benzoxazin-4-one) matrix maintains structural integrity well beyond standard processing windows. While baseline TGA curves indicate onset degradation near 350°C, controlled residence
