In contrast, during the heterogeneous nucleation, PNA plays a role of a
nucleating agent in the PA6 matrix and increases the nucleation density of the matrix.
Hyperform is a high-speed
nucleating agent for polypropylene that is said to promote extremely fast crystallization, resulting in improved processing speed and productivity, according to the company.
No burns or charring were found on the surface of the vapor foamed PC parts with NaCl as the
nucleating agent and water vapor as the blowing agent.
The production trials involved the company's 1,300-ton injection molder processing a masterbatch resin incorporating Milliken & Company's high-speed
nucleating agent, Hyperform.
The company's new pelletized foam concentrates contain a
nucleating agent that acts as a site for foaming during the gas-injected foam extrusion process.
Talc is an effective physical
nucleating agent for PLA and is commonly used as a reference to compare the nucleation ability of other additives [7-10].
It uses no chemical blowing agent--only talc as a
nucleating agent, so it is acceptable for food packaging, Meyer says.
It has been shown that the introduction of only 0.5 wt% of N, N'-dicyclohexylo-2,6-naphthaleno dicarboxy amide as [beta]-phase
nucleating agent leads to the formation of almost 100% [beta]-crystalline phase in isotactic PP, with a significant changes of the structure, morphology, and properties [10].
A major focus of Milliken's exhibit will be its newly launched Hyperform[R] HPN 210M
nucleating agent for injection-molded high-density polyethylene used in material handling applications.
However, to our best knowledge, the studies for An as a
nucleating agent to promote crystallization behavior of iPP are few.
