4. Application

Polypropylene is a kind of polymer made from propylene by addition polymerization. It is a colorless, odorless, nontoxic and translucent solid substance. It is widely used in the production of clothing, blankets and other fiber products, medical devices, automobiles, bicycles, parts, transportation pipelines, chemical containers, and food and drug packaging.


Polypropylene is a kind of thermoplastic synthetic resin with excellent properties, which is colorless and translucent. With chemical resistance, heat resistance, electrical insulation, high strength mechanical properties, good abrasive resistance and process-ability, polypropylene has been rapidly developed and applied in many fields such as machinery, automobile, electronic and electrical appliances, construction, textile, packaging, agriculture, forestry and fishery, food industry and so on. In recent years, with the rapid development of China's packaging, electronics, automobile and other industries, it has greatly promoted the development of China's industry. Because of its plasticity, polypropylene is gradually replacing wood products. Because of its high strength, toughness and wear resistance, polypropylene has gradually replaced the mechanical function of metal. In addition, polypropylene has good graft and composite functions, and has great application space in concrete, textile, packaging, agriculture, forestry and fishery.


Optical brightening agent OB-1 is a kind of optical brightener for polypropylene. In the finished product market of polypropylene, some of the producers use the recycled PP in a certain proportion, that will give yellowish or gray color to the finished products, which can not meet the customer’s requirements. OB-1 can absorb the ultraviolet light in nature and give out the visible blue light to neutralize the yellow color of the PP or recycled PP. So the finished product looks brighter and whiter. Besides, the PP products are usually processed under high temperature, normally between 170-270℃.OB-1 can work really well under this temperature. The dosage of OB-1 in PP(virgin) is about 100-200ppm, which is really little, but can increase the whiteness value over 10%. So it is a very high efficiency and low cost additive for polypropylene.


FQA

What is the Recommended dosage of OB-1 in PP products?

A: The dosage depends on the proportion of the virgin material and the recycled material. For 100% virgin PP, the dosage we recommend is as below:

From this chart, you can see, it’s important to control the dosage in appropriate percentage, over dosing will cause contrary effect. (the whiteness value in chart is only for demonstration,it’s not actual test value)


What is your minimum order quantity?

minimum quantity is 500kgs.


Can you send me samples?

Samples below 1kg are free to be dispatched by TNT or EMS, express service can cover most of major cities all over the world. For sample over 1kg, let’s negotiate with the express freight friendly.


Which level of quality are your products?

We have passed ISO9001 quality management system certification. In additional, we has been implementing lean management model since 2014. We can guarantee the top quality in our industry.
