Grease is an indispensable additive in engineering plastic products. Improves flow of polymers during molding and processing. Next, editor will briefly introduce some information about engineering plastic lubricants and briefly introduce two types of engineering plastic lubricants.

Lubricants can be divided into fatty acid amides, hydrocarbons, fatty acids, esters, alcohols, metal soaps and composite lubricants according to their chemical structure. According to type of use, it can be divided into internal lubricants (such as higher fatty alcohols, fatty acid esters, etc.), external lubricants (such as higher fatty acids, fatty amides, paraffins, etc.) and compound lubricants ( such as metal soap calcium stearate, fatty acid soaps, fatty acid amides, etc.).

Fatty acid amide lubricants include stearic acid amide, N,N-ethylenebisstearamide, oleic acid amide, erucamide, etc. Hydrocarbon lubricants include microcrystalline paraffin, liquid paraffin, solid paraffin, etc. Wait.

Highly effective masterbatch for modified polypropylene. This type of product is a special compatibilizer for polypropylene, which can increase bonding effect of polypropylene with glass fibers and fillers. Its addition is very small, only 5%-10%, can greatly improve mechanical properties and thermal properties of glass fiber reinforced polypropylene, filled polypropylene, etc., and give polarity to polypropylene resin to improve coating and adhesive properties. The modified polypropylene obtained using this product has found wide application in industries such as automobiles, motorcycles and household appliances.

Additives for silicone and plastic of GM series. Appearance is a white powder made from ultra-high molecular weight polysiloxane. It is commonly used as a processing aid for engineering plastics. This kind of additive is safe to use, easy to mix and has stable performance, easy to disperse in resin, can improve plastic processing fluidity and mold release, can reduce torque, reduce equipment wear, easy to fill mold, and reduce product reject rate. Reduce friction coefficient, improve surface silkiness, improve scratch resistance, improve fire resistance, etc.
