            專業的堿性染料、熒光增白劑系列及電子化學品系列產品生產制造商

            塑料用高效熒光增白劑OB-3

            一、技術指標:
            外 觀:黃綠色粉末
            有效成份:≥97%
            揮 發 份:≤0.5%
            熔 點:≥350℃

            二、產品特性及用途:
            1.熱穩定性良好,≥375℃,可應用于熔融塑料。
            2.OB-3被廣泛應用于聚酯纖維市場,以減輕變黃,提高白度,增加亮度。由于其良好的增白能力,良好的穩定性,并能與許多聚合物相容的特性,OB-3成為許多塑料產品的高效增白劑。
            3.適用于多種聚合物,以及回收聚合物,能顯著提高回收聚合物的白度,從而提高回收聚合物的價值。
            4.光學增白劑吸收紫外線輻射的功能和重新發出的藍光會減少聚合物的黃色光。在增白劑作用下,比如在TiO2的作用下,會產生亮白色的外觀。OB-3含有的白色增強因子能夠作用于聚合物產生比OB-1更藍的白色。

            三、使用方法:
            在新聚合物中建議加入25-300PPM,而回收的材料中建議加入量為300-400PPM。

            四、包裝:
            25公斤紙板桶雙層塑料袋內襯。

            一、Technical indicators:
            Appearance:yellow-green powder
            Purity:≥97%
            Volatile:≤0.5%
            Melting point:≥350℃
            二、Characteristics and applications:
            I .It has a good thermal stability(≥375℃),and could apply to molten plastic.
            2. It is widely used in the market of polyester fiber to reduce the degree of changing-to-yellow and it could increase the whiteness & brightness. Being the good whitening ability and stability, it can be compatible with many polymers with various properties.Now it becomes to a efficient brightening agent for many plastic products.

            3. It is applicable for various polymer and recycled of polymer,and it could significantly promote the whiteness of recycled polymer and improve the recycled polymer value.
            4. It can reduce the yellowish of polymer through the fuction of absorbing ultraviolet radiation and the effluent blue resent. For example,under the action of TiO2, it will effect the bright white appearance.The white enhancement factor contained in OB-3 can effect in polymer and make bluer white more than OB-1.
            三、Method of use:25-300PPM in new polymer and 300-400PPM for recycled material.
            四、packing:in 25kg fiber drums with double PE bags.
