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 coextruded semi-finished parts. Depending on equipment, processing conditions, and polymer types, UV-360 allows direct two-layer coextrusion 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. The use level of UV-360 is 0.2-10% by weight, and it can be readily incorporated into the polymer by conventional technique such as powder, solution or melt blending. UV-360 can be used alone or in a variety of blends and combinations with antioxidants, other UV absorbents and light stabilizers, and some other functional stabilizers where often a synergistic performance is observed. Packaging: Net weight:25kg/ cardboard drum. Storage and shipment: It is stable during storage and shipment, avoiding high temperature and humidity. |
