高效增白劑科萊恩熒光增白劑KSN

科萊恩熒光增白劑KSN是以高濃縮的添加方式，應(yīng)用在塑膠和聚酯光纖的光學(xué)增白劑。 
*高亮度的光學(xué)增白劑 
*對(duì)淺色調(diào)產(chǎn)品增白效果呈中性至藍(lán)紫相并使色澤更加明亮 
*在LDPE中有顯著的抗遷移性

特   性: 
外   觀 黃色粉末 
化學(xué)性質(zhì) 苯并惡唑派生物 
離子特性 非離子物質(zhì) 
熔   點(diǎn)250-300℃ 
耐儲(chǔ)存性 在潮濕和陽光照射的情況下不穩(wěn)定 
可稀釋度 不溶于水

溶解度（25℃） 
丙      酮      80mg/l 
二甲基 酰胺      800mg/l 
全 氯 乙 烯      250mg/l 
甲      苯      500mg/l 
甲醇（9：1）     970mg/l

熱穩(wěn)定性適合于塑膠和化纖聚合物的加工處理

用   途: 
KSN非常適合于處理合成高聚合體過程中的增白，如應(yīng)用在薄膜、注入成型、壓縮成型、化纖、硬毛和彩色蠟毛的染色。其使用方法類似于顏料、塑膠添加劑或化纖添加劑。

使用方法: 
在彩色塑膠中添加量為20-300ppm。 
透明塑料通常的添加量低于5-20ppm就已經(jīng)足夠。 
熱塑性PVC用量是100ppm，硬PVC為500ppm。 
聚酯纖維平均使用量為100-250ppm。 
該產(chǎn)品可以在酯交換反應(yīng)期間或者縮聚反應(yīng)及混合復(fù)配的時(shí)間添加，它也可以以增亮母粒的加工形式加入到塑料和纖維，因此增亮母粒的添加量在0.5-20%。

 Efficient whitening agent clariant fluorescent whitening agent KSN

Clariant fluorescent brightener KSN is a highly concentrated additive used in optical brighteners for plastics ａnd polyester fibers.

* high brightness optical whitening agent

* whitening effect of light-colored products is neutral to blue-violet ａnd makes the color brighter

* there is significant resistance to migration in LDPE

Features:Yellow powder

Chemical properties of benzooxazole derivatives

Ionic properties nonionic substances

The melting point of 250-300 ℃

Storage resistance is unstable in wet ａnd sunlight conditions

Dilution insoluble in water

Solubility (25 ℃)

Propyl ketone 80 mg/l

Dimethyl amide 800mg/l

Perchloroethene 250mg/l

Methyl benzene 500 mg/l

Methanol (9:1) 970mg/l

Thermal stability is suitable for processing plastics ａnd chemical fiber polymers

To use:

KSN is well suited for whitening processes in the synthesis of high polymers, such as film, injection molding, compression molding, chemical fiber, bristles, ａnd dyeing of colored waxes. Its use method is similar to pigment, plastic additive or chemical fiber additive.

Usage:

Add 20 to 300ppm of colored plastic.

Transparent plastics are usually added in quantities less than 5 to 20ppm.

Thermoplastic PVC maximum consumption is 100ppm, hard PVC for 500ppm.

The average usage of polyester fiber is 100-250ppm.

The product can be added during ester exchange reaction or condensation polymerization ａnd mixing ａnd compounding. It can also be added to plastics ａnd fibers in the form of brightening masterbatch processing. Therefore, the amount of brightening masterbatch is 0.5-20%.
