Application field

1, reduce the surface defects, such as common melt fracture phenomenon, improve the product surface brightness and smoothness.

2, scatter color more even, more luster.

3, reduce the machining process of mould wear and eliminate the phenomenon of mouth mold product material.

4, reduce the extrusion process of gel.

5, lower processing temperature and prolonging continuous processing time.

6, improve the product forming rate and size stability, reduce rejection rate.

A nucleating agent,

Nucleating agent is a kind of used to change the polypropylene crystallization behavior, and then change the crystal morphology, mechanical properties and thermodynamic properties and optical properties of functional additives.

1, polypropylene nucleating agent HBP

Adding nucleating agent modified polypropylene has good transparency, high gloss, excellent mechanical properties and processability characteristics, its scope is more widely used.

2, polyformaldehyde nucleating agent

Polyoxymethylene (POM) is a kind of excellent comprehensive properties of high crystal engineering plastics. Its high strength and hardness, good rigidity, and good abrasion resistance and fatigue resistance, and thus be used instead of non-ferrous metal and alloy, widely used in automobile, electronic appliances, construction, machinery and other industries. Owing to the high crystallinity of pom (general crystallinity of more than 60%), a gap, the impact strength is low, the molding shrinkage big shortcoming, and various other outstanding properties do not match, need further improvement. The performance of the improved polyformaldehyde material basically has two kinds of methods: strictly control the working conditions and adding nucleating agent. The study found that the impact strength of crystalline polymer is associated with the size and distribution of spherulites. Experiment mainly through in adding nucleating agent polyformaldehyde, change the configuration of polyformaldehyde spherulite, decrease the crystal size and in the process of forming shrinkage rate, improve its impact, optimization of polyformaldehyde performance, make its can satisfy some special requirements.

Second, the antioxidants

PP, PE, PS and other plastic in manufacturing, processing, storage and use process, by the factors such as light, oxygen, heat, oxidation degradation, often cause degradation plastics, plastic weatherability and durability, which affect the strength of the plastic and appearance. In order to prolong the life of polymer materials, inhibit or delay the oxidation degradation of polymer, usually using antioxidants.
