Nucleating agent is a new functional plastic additive
 

The nucleating agent is a plastic additive. Nucleating agent is suitable for incomplete crystallization resin such as polyethylene, polypropylene and so on. It aims to improve the transparency of the product by changing the crystallization behavior of the resin, increasing the crystallization speed, increasing the crystal density and promoting the grain size to reduce the molding cycle. Such as the nucleating agent, also known as transparent agent), surface gloss, tensile strength, rigidity, thermal deformation and other physical and mechanical properties of the new functional plastic additives.

According to the crystal form can be divided into α-crystal nucleating agent and β-crystal nucleating agent. At present, the global consumption of nucleating agent is about 5kt / a, of which 80% is dibenzylidene sorbitol (DBS) nucleating agent. The β-form nucleating agent has become a hotspot in the development of nucleating agents because of its improved mechanical properties and toughness.
The clear agent is a branch of the nucleating agent and about 90% of the transparent agent is used for the production of transparent polypropylene (C-PP). The transparent agent gives the original opaque PP with good transparency, making the low cost of C-PP not only in many ways can replace the more expensive polytrimethylene terephthalate (PET), polystyrene (PS) and poly Carbonate (PC) and other transparent plastic, and can improve the PP of the rigidity, impact strength, heat distortion temperature and other mechanical properties.
