Stearic acid,at low tempreture, as internal lubricants, at high tempreture as external lubricants
2.Fatty acid amide lubricant
1).Stearic acid amide:excellent external lubrication effect，Good transparency, dispersibility, gloss and electrical
insulation are also good, non-toxic,used as PVC, PS, UF resin processing lubricant, also as polyolefin smoothing
agent and anti-adhesion agent. The general dosage is 0.1%~2.0%.
2)N, N, ethylene bisstearate amide (EBS): widely used in smoothing agents, anti-adhesion agents, Externla
lubricants and antistatic agents. Non toxic, suitable for PE, PP, PS, ABS resin . The general dosage is 0.2%~2.0%.
3)Oleic acid amide: It can be used as a smoothing agent and anti-sticking agent for PE, PP, PA and other plastics.
It can improve the processing and forming performance. It also has anti-static effect. It can reduce the adhesion of
dust on the surface of products. It is a good internal lubricant in the processing and forming of PVC.
4)Butyl stearate : as an internal lubricant for resin processing, although incompatible with PVC, but can be used
as a lubricant for PVC transparent sheet extrusion, injection molding, calendering and defilm agent. The general
dosage is 0.5%~1.0%.
5)Glycerol trihydroxy stearate: It can be used as lubricant for PVC, ABS, MBS and defilm agent for synthetic
rubber. The general dosage is 0.25%~1.5%.
3. Hydrocarbon lubricants
1)Microcrystalline paraffin: Good thermal stability and lubricity are better than paraffin wax, but it will reduce
the gelation rate, so the dosage should not be too large,usually used with butyl stearate or high melting fatty acids,
used as external lubricants. The general dosage is 0.1%~0.2%.
2)Solid paraffin, which belongs to external lubricant, can improve the surface gloss of products, but its compatibility,
dispersibility and thermal stability are poor.manly used for PVC, PE, PP, PS, ABS, PBT, PET, cellulose and other plastics.
3)Polyethylene wax: It has good mid-term and late lubricity, can play the role of anti-adhesive. It can be used as
pigment dispersant in color masterbatch processing, lubricant in PVC-U, lubricant and release agent in PVC, PE,
PP, ABS, PET, PBT plastic forming. The general dosage is 0.1%~0.5%.
Oxy polyethylene wax: it has good internal and external lubricity, and gives the product good transparency and
gloss. It is mainly used in PVC, PE, PP, ABS, PBT, PET and other resins. Dosage 0.1%~1.0%.
Ft wax: mainly used as external lubricants, dispesant agent, mianly used on PVC, masterbatch
