As a effective plastic additive, nucleating agent can increase the peak crystallization temperature of the resin and accelerate the curing speed of the resin; with excellent high impact resistance.

A nucleating agent has a surface charge that is opposite to the partial charge of the chemical moiety of the polymer. It accelerates its rate of crystallization, and a melting point is greater than the melting point of the melt processible polymer.
This nucleating agent is used among other fluoro polymers for nucleation of FEP. The oppositely charged surface of nucleating agents exhibits a natural affinity through the electrostatic interaction between nucleating agent and polymer.
(Shanghai Colors is the original manufacturer of Pigment and Dyes for Tin Printing Inks, contact us for sample to test.)
FEP due to the presence of fluorine has negative charge therefore the nucleating agent of choice should have positive charge. The Melting point of the nucleating agent above the Melting point of the melt processible polymer provides improved dispersion of the nucleating agent in the melt processible polymer.Also, the nucleating agent begins formation of crystals at a higher temperature than the melt processible polymer.
Suitable nucleating agents include: phosphonium salts (triphenyl phosphine, tributyl phosphine, trimethyl phosphine, dimethyl phenyl phosphine, methyl diphenyl phosphine, tris(2-ethylhexyl) phosphine, tetrabutyl-phosphonium hexafluorophosphate, tetrabutyl-phosphonium-hydrogen sulfate, and tetrabutylammonium-phenylphosphonate), pyridinium salt (tritylpyridinium tetrafluoroborate), pyrrolidinium salt (1-butyl-1-methylpyrrolidinium bromide), sulfonium (triphenylsulfonium tetrafluoroborate), sulfonate (sodium octyl sulfonate), phosphonate (phosphonic acids, esters, and salts; phosphinic acid, esters, and salts; phosphonamides; phosphinamides) and phosphonate (tetrabutylammonium-phenylphosphonate).
