Characteristics: The physical and chemical properties of hexyl bisstearamide are very similar to those of ethylenyl bisstearamide (EBS). As a plastic additive, it has the following functions:
(1) Lubricating mold release agent. It has excellent lubricating and demolding properties for ABS and AS resins, and also demonstrates outstanding performance in the molding of polyoxymethylene, polycarbonate, etc.
(2) Anti-sticking and anti-slip agent. The surface of the polymer film adheres, causing inconvenience in application. By taking advantage of the limited compatibility of hexyl bisstearamide with polymer resin, an appropriate amount of it is added to the formula. After molding, it slowly migrates to the surface of the product, forming a molecular layer to achieve the purpose of anti-sticking and smoothness.
(3) Auxiliary stabilizers. It shows obvious light stability and thermal stability even when a small amount is added.
(4) Nucleating transparent agent. After addition, it can shorten the nucleation time, promote the thinning of the resin structure, and thereby improve the mechanical properties and transparency of the product.
(V) Pigment dispersants, fillers and surface treatment agents. Pigments or fillers treated with this substance can improve their dispersion and coupling in polymers.
(6) Solder raw materials > antioxidant thixotropic agent > Prevent delamination of solder paste, enhance the stability of solder paste, and prevent problems such as deformation, collapse and edge diffusion of solder paste during preheating after printing.
In addition, it is used as a surface brightener for rubber. In coatings, it can act as a dispersant to achieve a matting effect. In the chemical fiber industry, it can enhance the heat resistance and weather resistance of polyester fibers and polyamide fibers, and endow them with certain antistatic effects. Therefore, bisstearamide has broad application prospects in the field of polymer processing. This product is used as a plastic additive to enhance transparency and lubricity and can be applied in PVC transparent sheets. In addition, it is used as an anti-caking agent, compounding agent and dispersant in the processing of polymer materials, and has the functions of lubricating, anti-sticking and anti-static.
When the addition amount of hexyl bisstearamide is 2 ‰ to 4 ‰ of the resin, the transparency of the PVC sheet sample is better than that when EBS is used as the lubricant, and the lubricity is comparable to that of EBS.
Packaging and storage: The product is packed in composite bags, with a net weight of 25kg per bag. This product should be stored and transported in accordance with the regulations for general chemicals.
