Many additives are used in PVC foam products, such as stabilizer, lubricant, regulator, etc. today, Qingdao sainuo polyethylene wax manufacturer will take you to know about these additives.

In this article, Qingdao Sainuo polyethylene waxmanufacturer will take you to know the relevant knowledge of plastic processing additives.

For PVC foamed board, whether calcium carbonate filling affects the foaming performance is very complex, which mainly depends on the size, addition amount, dispersion and water content of calcium carbonate. If these factors of calcium carbonate are used properly, it can promote foaming, otherwise it will seriously affect foaming.

PVC pipe formula is mainly composed of PVC resin and additives. According to their functions, additives are divided into heat stabilizers, lubricants (pe wax​), processing modifiers, impact modifiers, fillers, anti-aging agents, colorants, etc.

High-purity polypropylene wax, moderate viscosity, high melting point, good lubricity, and good dispersibility. It is currently an excellent auxiliary for polyolefin processing, high temperature resistance, and high practicability.

White Masterbatch has the characteristics of bright color, dazzling, high coloring strength, good dispersion, high concentration, good whiteness, strong covering power, good migration resistance and heat resistance. It is widely used in injection molding, blow molding, wire drawing, tape casting, extrusion, film blowing, foaming, sheet, pipe, pelletizing, hollow, EVA, bottle blowing, sheet, household appliances, toys, packaging materials, etc Wires and cables, plastic bags, automobiles, building materials, sports and leisure products, packaging bags, packaging bottles and other plastic products industries.

Qingdao Sainuo polyethylene wax manufacturer will show you the solution to the problem of precipitation and migration of PVC plasticizer.

Polyethylene wax (PE wax), also known as polymer wax, is called polyethylene wax for short. Because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance, it has been widely used. In normal production, this part of wax can be directly added to polyolefin processing as an additive, which can increase the luster and processability of products. As a lubricant, it has stable chemical properties and good electrical properties.

PE wax​ is a kind of very low molecular weight high pressure polyethylene. Pe wax is generally divided into four types: oligomer wax, cracking wax, convergent wax and blending wax.

Qingdao Sainuo Zinc stearate​ can inhibit initial coloring, avoid vulcanization pollution, and with good lubricity, mold release and adhesion.

Qingdao Sainuo white flake pe wax has good whiteness, good hardness, good brightness, good penetrability, crispness, small smell, smokeless, high hardness; it has low thermal weight loss, low rheological index, good lubrication dispersion; it can solve the problem of uneven feeding in weight loss measurement; it nearly perfect replacement of all high-quality oligomers, can replace 0020P, 0040P.

Lubricant pe wax has stable index, high melting point, high hardness than oligomers and low weight loss, it can improve the processing performance of products; Dispersant EBS has low acid value, sufficient reaction, excellent late heat stability, It has good whiteness, uniform particle size, good brightness dispersion effect, good friction resistance, and meet FDA requirements.

Internal lubrication has a high affinity with resin, its role is to reduce intermolecular force, improve the dispersion of raw materials components; external lubricant and resin affinity is small, its role is to reduce the friction between resin and metal surface.

Super fine powder, easy to disperse and lubricate well

Disoersant 222 with low acid value, sufficient reaction, excellent late heat stability, good whiteness, uniform particle size, good brightness dispersion effect, good friction resistance, and meet FDA requirements.
