High Purity β- Crystal Nucleator , Nuclear Chemistry White Raw Powder

Nucleating Agent , Nucleator , β-crystal Nucleating Agent , β type nucleating agent for PP , PP β-crystal Nucleator

Application of β-crystal Nucleating Agent NB-328:

NB - 328 is an economic and effective β type nucleating agent for PP. By inducing crystallization obtain beta - type polypropylene of high beta crystal type content, and gives products with good impact resistance, heat deformation and high porosity. It achieve the unification of polypropylene impact resistance and thermal deformation. NB - 328 especially suitable for PP - R tube, automotive, home appliances and other PP product required high impact resistance and heat deformation. It can also be used for PP paper high porosity, printing film products processing.

Performance and Quality Index of β-crystal Nucleating Agent NB-328:

Chemical composition: aryl amide

Application feature of β-crystal Nucleating Agent NB-328:

NB - 328 is an economic and effective PP beta crystal nucleating agent. It has the effect of increased the crystallization rate, crystallinity and beta crystal type conversion which giving products good impact resistance, heat deformation and high porosity. Test data show that the isotactic and random PP add 0.3% of the NB - 328, beta - type conversion rate is above 90%. Both impact strength and heat distortion temperature are significantly improved. The impact strength is increased about 4 - 5 times, thermal deformation temperature can reach 127 deg.C. Compared with other types beta crystal nucleating agent, NB-328 has the characteristics of non-staining, improved processing of products, low price, and good stability of beta crystal form. This product can be used directly with PP powder. It also can be prefabricated to masterbatch and then used for secondary processing. The recommended dosage is 0.1 ~ 0.3% of PP base material.

The Recommended dosage of β-crystal Nucleating Agent NB-328: 0.1-0.3%

Package and Storage of β-crystal Nucleating Agent NB-328:

10kgs aluminum foil bag, 2bag in one carton. Storage in cold and dry place, it may be preserved long while not destroying the seal, Please bundle the bag after used.

Difference of alpha crystal form PP and beta crystal form PP

There is a great difference in mechanical properties between the alpha crystal form polypropylene and beta crystal form polypropylene.

Alpha crystal form PP has the effect of increasing rigidity and the temperature of heat deformation, resisting creep, reducing turbidity and improving the surface gloss of products.

The elastic modulus, yield strength of beta crystal type polypropylene is lower than alpha crystal type polypropylene, but the performance of tensile breaking strength, elongation at break and impact toughness is significantly superior to alpha crystal type polypropylene, can make the modification of polypropylene products is difficult to realize the impact resistance and thermal deformation temperature change at the same time the contradiction to achieve an organic unity.

Beta crystal form can also give a good porous structure to polypropylene products and improve its permeability, printability and other properties. Moreover, although the melting point of beta crystal type of polypropylene is lower than alpha crystal type of polypropylene, but the thermal deformation temperature of beta crystal type PP is higher than alpha crystal type polypropylene. The reason may be that Lu crystal type polypropylene thermodynamic performance is not stable, melting recrystallization occur in the process of heating up, into the alpha crystal type polypropylene, and generate alpha crystal type polypropylene melting point higher than the melting point than the original.
