Product Description

EBS is a polar amide wax with balanced internal and external lubrication effects. It exhibits excellent wetting and encapsulation capacity for polymer resins, pigments and fillers. It serves as an efficient dispersant, slip agent, anti-blocking agent and mold release agent. It can reduce melt viscosity and processing torque, improve surface smoothness, scratch and abrasion resistance of finished products, with minor impact on transparency. It is widely used in PVC, polyolefins, engineering plastics, color masterbatches, powder coatings, printing inks, paper coatings, powder metallurgy and casting release agents. It can also act as an anti-glass-fiber blooming additive for glass-fiber reinforced plastics.

Typical Properties

Product Features

1. Excellent internal lubricant with good compatibility with polar resins; reduces melt viscosity and cuts processing energy consumption.
2. High-performance pigment dispersant suitable for high-concentration masterbatch; inhibits pigment agglomeration and improves tinting strength.
3. For coatings and inks: enhances slip, abrasion resistance, scratch resistance and anti-blocking property; low haze, suitable for transparent systems.
4. Eliminates glass fiber blooming of glass-fiber reinforced engineering plastics such as PA, PBT and ABS, and noticeably improves surface finish.
5. Functions as a degassing aid in powder coatings to reduce pinholes.
6. Low volatility, good thermal stability and low odor; synergistic lubrication can be achieved when compounded with PE wax and PP wax.
7. Antistatic agent for synthetic fibers: 33% EBS can be used as an antistatic agent for synthetic fibers.
8. It can be used as a melting point raiser for petroleum products. When added into adhesives and waxes, it delivers good anti-caking and mold-release performance.
9. When added into asphalt, it raises the softening point, lowers viscosity and improves resistance to water and acid corrosion.
10. When added into paint removers, it improves the properties of wax layers.
