Chemical
Name |
2,2’-methylenebis(6-(2H-benzotriazol-2-yl)-4-1,1,3,3-tetramethylbutyl)phenol)VIOCHEM UV- 360 |
Structure |
 |
Applications |
TINUVIN 360 applications include acrylic resins, polyalkylene
terephthalates, polycarbonates, modified polyphenylene ether or sulfide compounds, polyamides, polyacetals, polyolefins, styrenics, elastomers and high performance plastics. |
Features/Benefits |
TINUVIN 360 is particularly suitable for processing and aging
conditions where high loads, low volatility and good compatibility are required. The specific objective is to achieve high UV-screen performance and minimize sublimation through vents as well as prevention of deposits on molds, chill-rolls or calibrators. It can prevent exudation/crystallization on end-parts during manufacturing or exposure to high service temperatures. Such requirements are especially critical for complex moldings, fibers, sheets, twin wall sheets, thin films, adhesive layers and laminated or co-extruded semi-finished parts. Depending on equipment, processing conditions, and polymer types, TINUVIN 360 allows direct two-layer co-extrusion of sheets without the use of a neutral third top layer to prevent sublimation and/or deposits generated by the thin, highly UVA-loaded second layer. |
