塑料用高效荧光增白剂OB-3

一、技术指标:
外 观:黄绿色粉末
有效成份:≥97%
挥 发 份:≤0.5%
熔 点:≥350℃

二、产品特性及用途:
1.热稳定性良好,≥375℃,可应用于熔融塑料。
2.OB-3被广泛应用于聚酯纤维市场,以减轻变黄,提高白度,增加亮度。由于其良好的增白能力,良好的稳定性,并能与许多聚合物相容的特性,OB-3成为许多塑料产品的高效增白剂。
3.适用于多种聚合物,以及回收聚合物,能显著提高回收聚合物的白度,从而提高回收聚合物的价值。
4.光学增白剂吸收紫外线辐射的功能和重新发出的蓝光会减少聚合物的黄色光。在增白剂作用下,比如在TiO2的作用下,会产生亮白色的外观。OB-3含有的白色增强因子能够作用于聚合物产生比OB-1更蓝的白色。

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

四、包装:
25公斤纸板桶双层塑料袋内衬。

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.
