When The Vegetarian Resource Group's Food Ingredients Guide was first published in 1997, animal sources of stearate
compounds used in foods were common.
Though calcium stearate
and sodium stearate
have been the primary metallic stearates
used for industrial and commercial applications, magnesium stearate
has recently replaced these substances in many various applications.
High-purity metallic stearates
as internal/ external lubricants include:
A: Much of what is being said about magnesium stearate
is an unscientific interpretation of the literature.
For instance, if a colorant is being developed for use in a WPC formulation that includes coupling agents to help improve physical properties, standard colorants that incorporate metallic stearates
may actually limit the effectiveness of the coupling agent.
com/research/8qxg87/research_and) has announced the addition of the "Research and Investment Strategy Analysis of China's Calcium Stearate
Market, 2011-2016" report to their offering.
Additives reportedly can replace existing processing aids, which depending on the plastic, can range from primary and secondary antioxidants, nucleating agents in PP, as well as lubricants ranging from metallic stearates
, amides and fatty acid additives used in polyolefins and styrenics to waxes used in PVC.
The SXT 2000 Series of lubricants are blends of metallic stearates
and nonmetallic lubricants, such as ester-based compounds and waxes, that offer improved processing and finished product attributes at a price only marginally higher than that of traditional all-metallic products, according to Ferro.
, a nontoxic and nonirritant carboxylate of calcium, is one of the most commonly used metallic stearates
in industrial and commercial applications.
In combination with stearates
products provide internal and external lubrication.
The resin additive is a 100% active, synergistic blend of complex organic materials that do not contain silicone or metallic stearates
MoldWiz INT-33VPE, free of animal derivatives and metallic stearates
, is designed to enhance flow and reduce surface coefficient of friction in polyolefins and styrenic resins.
