1,3:2,4-Bis(3,4-dimethylobenzylideno) sorbitol Technical ?99%

Name:ZN-3S English-name:1,3:2,4-Bis(3,4-dimethylobenzylideno) sorbitol

CAS No: 135861-56-2

Nucleating Transparent Agent ZN-3S , Appearance :White Powder ;Purity (HPLC) ≥99.0%;Melting Point > 260℃;95% of the size:≤30um;Average particle size:≤10um;Loss on Drying <0.5%; Ash <0.5%

Purpose:

   The most widely used world polypropylene (PP) transparent agent is the third generation of Sorbitol Nucleating Agent.Zhonghui ZN-3S ,the same products are imported from the United States (MILLAD) 3988, It can provide the highest possible transparency for business applications. Applications include food and storage containers, bottles, packaging, medical equipment, as well as innovative products such as sheet.

1.a. Best transparency  b. cost reduction c.Weight reduction d.Increase chemical resistance

2.Zhonghui ZN-3S is a breakthrough in polypropylene (PP) purification technology, The formula is correct, and the grade of PP is relative, Using this additive can improve the transparency, increase the yield and yield, and improve the physical properties. Polypropylene with low cost and usability make it widely used. but in some cases its advantages are limited by its transparency. Now use the Zhonghui ZN-3S, polypropylene can be extremely clear and can be widely used in applications where the design is important. In terms of design, packaging and material selection, The purified polypropylene by ZN-3S provides great flexibility to the designer .

In terms of design, packaging and material selection, The purified polypropylene by ZN-3S provides great flexibility to the designer .

4. The advantages of polypropylene purified by ZN-3S:

High transparency: transparency, high gloss, smooth surface of polypropylene;

 High yield: Polypropylene treated by ZN-3S, high yield and yield;

High efficiency: Polypropylene cost-effective and low density, making it a very attractive alternative to other resins

Wide use: the sink of ZN-3S purification in polypropylene, toughness, flexibility, rigidity, heat resistance, moisture resistance, chemical resistance and suitable for food contact and provide superior comprehensive performance;

Performance improvement: compared with the UN purified polypropylene, the performance of the ZN-3S treated polypropylene was improved, especially with higher rigidity and thermal deformation temperature;

Processability: ZN-3S will not be cooled out of polypropylene surface, will not produce odor;

6.Zhonghui ZN-3S how to take effect

Usually polypropylene is slowly crystallized into relatively large crystals called grains, As the crystal is larger than the visible wavelength, the incident light is scattered by the crystal, thereby reducing the transparency and increasing the ambiguity, When polypropylene was purified by ZN-3S, the crystallization rate of the polymer increased exponentially, Because of the increase in the number of crystals grown in the same volume and the decrease of the crystal size, the result is that the crystal is smaller than the wavelength of light, and the transparency is enhanced after the light is allowed to pass.

9.Application of polypropylene purified by Zhong Hui ZN-3S

Polypropylene containing ZN-3S has many uses. In most manufacturing situations, new product designers can flexibly select polypropylene without or without ZN-3S purification. The removal of other materials and the use of purified polypropylene will reduce costs and improve efficiency in most potential applications. The following table gives an overview of the possible applications that may be achieved through a variety of machining processes.

Quality standards: ZN-3S quality and quality of the United States and (MILLAD) 3988 consistent quality, the price is less than half price of the United States (MILLAD).
