EBS – ethylene bis-stearamide synthetic wax, is an excellent internal and external lubricant, and can also be used as a processing aid and a dispersant for pigments.
Chinese name: Ethylene bis-stearamide
Production raw materials: stearic acid and ethylenediamine
Appearance: white or light yellow, similar in shape to solid wax, hard and tough
Advantages: It does not affect the physical properties of the product such as thermal stability, appearance, color and transparency
Function: internal and external lubricants; antistatic agent; nucleating and transparent agent; dispersing agent; mold release agent; anti-caking agent; matting agent; Fat (MI)
EBS product features
1. Small particle size, can reach dispersion grade fineness
2. Excellent internal and external lubricity, improve production efficiency
3. Can be used as a dispersant for fillers and pigments
4. It has no effect on product performance, and can even improve product stability to a certain extent
How EBS works
Internal lubricant: Due to the presence of polar amide groups in the EBS molecule, it has a processing lubricating effect and a low-temperature anti-sticking effect on the polymer resin. EBS can be inserted into the polymer resin to reduce the interaction between the resin molecules.
External lubricant: EBS has limited compatibility with resin, and can be pulled from the inside of the resin to the surface, which reduces the mutual friction between resin particles, resin melt and processing equipment, prevents it from adhering to the metal surface, and plays an important role. External lubrication.
EBS is used as a lubricating release agent in plastic processing, which can improve the quality of plastic products and improve the appearance of products.
What are the applications of EBS?
Main application (1): plastic
In many thermoplastic and thermosetting plastics as internal and external lubricants, the most representative such as ABS, PS, AS, PVC, can also be used in PE, PP, PVAC, cellulose acetate (cellulose, Acctate), nylon (Nylon) , phenolic resin (pheonolic-Resin), amino plastics, etc., has a good finish, release.
Main application (2): Rubber
Adding EBS to synthetic resin and rubber has good anti-sticking and anti-caking effects. EBS is applied to rubber products such as automobile floor mats and drainage pipes to increase the surface gloss. In the processing of fluororubber, it can improve the performance of rubber particle lifting, processing and vulcanization.
Main application (3): pigment, filler dispersant
EBS is used as a pigment dispersant for plastic and chemical fiber masterbatches, such as ABS, PS, polypropylene, polyester masterbatches.
EBS can also be used as a diffusing powder for plastic color matching.
Depending on the amount of pigment filler added, the amount added is 0.5~5%.
Main Application ( 4): Powder Coatings
EBS can be used as a flow aid for powder coatings.
Main applications ( 5): coatings, inks
In the manufacture of coatings and paints, adding EBS can improve the effect of salt spray and moisture resistance; adding this product to coatings can improve the performance of paint strippers and improve the leveling of the surface of baking enamels. It can be used as a matting agent in printing inks and furniture polishes.
