Talk about the role of Rubber Antioxidant tmq in adding to plastic products

- Jul 10, 2018-

Rubber Antioxidant TMQ is certain polyurethane foam plastics such as high rebound foam, microporous elastomer and semi-rigid bubble is a commonly used additives, such as to improve and adjust the performance of polyurethane foam plastic has very big effect. In the plastics industry, Rubber Antioxidant TMQ is mainly used in epoxy resin, unsaturated polymer, phenolic aldehyde, polyethylene, polyvinyl chloride and other plastics. 

Commonly used Rubber Antioxidant tmq include imidazole Rubber Antioxidant tmq, benzoic anhydride, diethylenetriamine, tert-butylperoxy ethane, hexamethylenetetramine, etc.

Rubber Antioxidant tmq are mostly active hydrogen compounds containing multi-functional groups, such as polyols and polyamines with small molecular weight. Polyols containing amino and tert nitrogen atoms can also be used as Rubber Antioxidant tmq. 

They also catalyze the reaction of isocyanate and polyol. Examples include ethanolamine, di-2-phenylamine, triethanolamine, and alkyl alcohol derivatives of piperazine. Triethanolamine, diethanolamine and other alkanolamine compounds are commonly used as antioxidants for high resilient foam and semi-rigid foam systems. With the opening of the small molecule polyhydric alcohol or alcohol amine agent and the oxidation of ethylene polymerization and the relative molecular mass of the low viscosity of hundreds of polyols can be used as a formula, such as RIM half hard bubble with aniline and toluene diamine with ethylene oxide addition of low molecular weight and high aromatic polyols activity, can also be used for research in motion (RIM) microporous elastomer and semi-rigid foam formula, etc.

Plastic add one Rubber Antioxidant TMQ aim is to make a linear macromolecule or branched chain of linear macromolecular structure between crosslinking resin molecules, resulting resin molecular structure by linear transformation for the net type or size of molecular structure, and transform the physical and mechanical properties of the plastic and plastic melt rheological properties.

In most cases, in the process of plastic processing crosslinked polymer are active center on the macromolecular reaction, active functional groups or active point, or active center and Rubber Antioxidant TMQ asked for response. These active center is able to provide a reaction active group, under certain conditions, such as the initiator or the presence of catalyst, can make the resin molecules produces crosslinking reaction, thus forming shape structure.
