EBS分子结构中，两端为非极性长链烷基，中间是极性双酰胺基，这种对称中位极性结构，赋予EBS优良的润湿和渗透能力。对各类颜料和填充剂粉体有显著的润湿和分散作用。EBS分子中的极性基和非极性基的良好匹配和较高分子量，使它既不溶于醇类，又不溶于油类。这种均衡性质使它在大多数树脂中具有适中的相容性，并呈现出优良的内部和外部润滑效果。可作为润滑剂、降粘剂、脱模剂、爽滑剂用。 In the molecular structure of EBS, both ends are non-polar long-chain alkyl groups, and the middle is polar bisamide groups. This symmetrical neutral polar structure gives EBS excellent wetting and penetrating capabilities. It has significant wetting and dispersing effects on various pigments and filler powders. The good match of the polar group and the non-polar group in the EBS molecule and the higher molecular weight make it insoluble in alcohols and oils. This balanced nature makes it moderately compatible in most resins and exhibits excellent internal and external lubrication effects. It can be used as lubricant, viscosity reducer, release agent, slip agent.
1.橡胶中：在橡胶工业中，该助剂可用为胶料的抗粘剂、润滑剂和脱膜剂，以及橡胶的表面处理增光。 1. In rubber: In the rubber industry, this additive can be used as an anti-sticking agent, lubricant and release agent for rubber compounds, as well as for surface treatment of rubber.
2.化纤中：EBS可以提高聚酯，聚酰胺纤维的耐热耐候性、流动性，并赋予一定的抗静电效果。 2. In chemical fiber: EBS can improve the heat and weather resistance, fluidity of polyester and polyamide fiber, and give a certain antistatic effect.
3.颜料、填料分散剂：在塑料（化纤）色母粒（如ABS、PS、丙纶、涤纶母粒）中，EBS作为分散剂、扩散粉，可提高颜料、填料的分散性和加入量，提高加工效率，并可提高色母粒的鲜艳度和光亮度。 3. Pigment and filler dispersant: In plastic (chemical fiber) masterbatches (such as ABS, PS, polypropylene, polyester masterbatches), EBS is used as a dispersant and diffusion powder to improve the dispersibility and added amount of pigments and fillers. Improve processing efficiency, and improve the vividness and brightness of masterbatch.
4.粉末涂料中：EBS可用作粉末涂料用流动助剂。 4. In powder coatings: EBS can be used as a flow aid for powder coatings.
5.涂料、油墨中：涂料及油漆制造时，添加0.5~2%EBS能提升盐雾及防潮效果；在涂料添加本品，能够提高颜料、填料的均匀分散性，改善烘干漆的表面流平性，防止漆皮剥落，并改善耐水、耐酸碱性。在硝基漆中还可以起到消光作用。在家具抛光剂和印刷油墨中可用为消光剂。 5. In coatings and inks: when manufacturing coatings and paints, adding 0.5~2% EBS can improve the salt spray and moisture-proof effect; adding this product to the coatings can improve the uniform dispersion of pigments and fillers and improve the surface flow of the dried paint Flatness, prevent paint peeling, and improve water resistance, acid and alkali resistance. It can also play a matting effect in nitrocellulose paint. It can be used as a matting agent in furniture polishing agent and printing ink.
6.塑料中：在许多热塑性和热固性塑料中作为内部和外部滑剂，具代表者如 ABS、PS、AS、PVC，亦可应用于PE、PP、PVAC、醋酸纤维素、尼龙、酚醛树脂、氨基塑料等，具有良好的光洁度、脱膜性。 6. In plastics: used as internal and external lubricants in many thermoplastic and thermosetting plastics, such as ABS, PS, AS, PVC, and can also be used in PE, PP, PVAC, cellulose acetate, nylon, phenolic resin, Amino plastics, etc., have good finish and release properties..
