2016-7-20 9:48:02 Traffic：

Erucic acid amide as a white waxy solid neutral, resin, paraffin wax (microcrystalline wax) and other good compatibility of dyes and pigments and other substances have good dispersion. In the plastic processing, can play smooth, lubrication, mold release, anti-stick, anti-caking, moisture resistance, antistatic, dispersion and increase product surface brightness and so on, is an ideal new efficient plastic processing lubrication aids agent.

Application of high-pressure polyethylene

In the high-pressure polyethylene (LDPE) film added erucic acid amide compound to prevent dust accumulation in the surface of the article is attached, but also improve the humidity resistance and antistatic properties, significantly reduce dynamic and static coefficient of friction, high speed extrusion line, improve the efficiency of blowing (extrusion, calendering) is to improve the opening of resin and ease of processing the film, effectively prevent the adhesion between the film significantly reduced fish eyes and streaks film surface to improve the cleanliness, the tensile strength , elongation at break, reduced dielectric constant, power consumption is reduced by 10% at the same screw speed - 30%, under the same power consumption may increase with 30% yield - 60% when added directly to the resin should be noted control the amount and uniformity of dosage to prevent the extruder screw slippage, not too little or too much, so as not to affect the smoothness of the film product. And other additives may also be: made together (such as calcium sulfate, silicon dioxide, stearic acid amide, hydrous magnesium silicate, stearic acid salts, pigments, dyes, antioxidants, preservatives, etc.) masterbatch was added . With fillers, insulation aids, anti-mist additives complex, made of composite multifunctional masterbatch. The product of the inorganic flame retardants good dispersion, containing the product of polypropylene flame retardant masterbatch, flame retardant may be a corresponding reduction in the amount of machinery to improve product performance, reduce costs, is the development of new flame retardant masterbatch material indispensable aid. As a high-density polyethylene (HDPE) packaging film smoothness agents, after adding the film thickness uniformity can prevent wrinkles. EVA is used as packaging film and agricultural film anti-blocking and anti-fogging agent. After the polyethylene pipe compound added erucic acid amide, extrusion rate increased by 20%, to produce the pipe surface bright, smooth and delicate.

Linear low density polyethylene Application

LDPE LLDPE films having excellent tear than anti-puncture ability, better aging resistance and higher transparency, but the high processing temperatures, larger melt viscosity of LDPE unit processing difficulties. We must use efficient lubricant to improve its workability. Add in the resin of 0.1% - 0.3% of erucic acid amide, dynamic and static coefficient of friction can be reduced to the movable K = 0.12, K = 0.11 static, make LLDPE and LDPE extrusion and blow molding on the same device, and in at the same screw speed to reduce power consumption by 8% - 25%; 25% increase in the power consumption of the same - this extrusion rate of 40%, lower processing temperatures, improved and easy opening properties and fluidity of the resin film, enhancement film transparency, gloss, elongation, rupture strength and the like. Erucamide is to achieve high-speed extrusion, low cost, high quality production of LLDPE film is an important additive. Erucic acid amide LLDPE (HDPE) plastic cable insulation materials and communication cable jacket, the processing host current significant decline in working out the cable surface smooth and delicate, to achieve high-speed extrusion, significantly reducing costs.

Application in PVC

No drop in agricultural film added surfactants easily cause bleeding to the surface adhesion between each film, erucic acid amide was added to prevent non-drip film adhesion, and to improve its slip and non-drip. Erucic acid amide may be added directly or added to the masterbatch. Used as a transparent rigid PVC packaging film (twist, wrappers) of a slip agent. Hard transparent PVC packaging (agricultural, industrial) film because of its insulating properties easily understood accumulation of electrostatic charge, and easily lead to electrostatic film adhesion, easy cleaning surface of the film, just add erucamide, to prevent sticking and improve the openability. Plastic doors and windows (building plastics) erucic acid amide, make doors and windows white color, no pitting, surface smooth and bright.

Application of Polypropylene

BOPP film is used as anti-blocking agent and slip agent, or in combination with other additives (or pigment) added together into a master batch. High transparency polypropylene composite film additive. Erucic acid amide inorganic filler having a high dispersion characteristics, in the modified polypropylene can be used as a dispersant, but can also improve the plastic melt index, increased surface brightness, smoothness, lower processing temperatures. As an anti-blocking composite film of transparent polypropylene slip agents,

Application of other polyamide resin (the PA, nylon) resins, phenolic resins, urea-formaldehyde resin, three polyoxypropylene amine resins, polyester resins, cellulose acetate and cellulose nitrate and a lubricant release agent. Can improve the flow properties of the resin itself, increase productivity, improve the appearance of the product quality, increase product smoothness, prevent and overcome the mucous membranes, improve ease of processing.

Polyethylene cable lubricant

Erucic acid amide compound added in the cable, the friction coefficient from 0.7 down to 0.06, while improving coloring properties and dispersibility of carbon black, etc., to achieve high-speed cable extrusion pellets to improve the smoothness of the inner wall of the cable jacket pipe.

Plastic ink application

Plastic ink (paint coatings) can be added to improve the printing performance erucamide, the lubricating properties of the ink, and to improve dispersion performance, enhanced water resistance, scratch resistance, anti-fade resistance, abrasion resistance; in addition can also improve ink spreadability printed surface, fixing and sliding property, the printed fonts, pattern lines clear, bright color. Polyethylene wax and mixed use, printing ink components in the best anti-offset agent and scratches. In the paint industry, as pigment grinding aids and dispersants. Also as paraffin paperboard coatings, powder coatings dispersants and lubricants.
