Why need to add nucleating agent for plastics?

That is because in the molten state, since the nucleating agent provides the required crystal nucleus, the polymer is transformed from the original homogeneous nucleation to the heterogeneous nucleation, thereby accelerating the crystallization rate, refining the grain structure, and helping to improve the product rigidity, shorten the molding cycle, maintain the dimensional stability of the final product, inhibit light scattering, improve the transparency and surface gloss and the physical and mechanical properties of the polymer (such as stiffness, modulus), shorten the processing cycle, etc.

What is Nucleating Agent RT-PP03 for PP?

Nucleating Agent RT-PP03 for PP is 3rd generation of Nucleating Agent,

high performance sorbitol based and reduces haze and improve

the clarity of polypropylene, and it can improve the heat

temperature, and rigidity etc.

The alpha-type third-generation nucleating agent mainly improves impact resistance and transparency in polypropylene materials. Increase rigidity by increasing crystallization speed. Significant improvement in rigidity and impact resistance，mainly used for polypropylene pipes, polypropylene sheets, polypropylene transparent lunch boxes, polypropylene low pressure film products, etc.

What is the differences between Nucleating Agent RT-PP02 and Nucleating Agent RT-PP03 ?

Nucleating Agent RT-PP02 is equivalent to US Miliken 3940, has the smell of bitter almond, but the price is low.

Nucleating Agent RT-PP03 is equivalent to Miliken3988, the product is odorless and the effect is better

In fact, the effect of Nucleating Agent RT-PP02 and Nucleating Agent RT-PP03 cannot be seen with the naked eye, but the transparency can be seen in the laboratory test.
