Amorphous Polyalphaolefin APAO Versatile Chemical

Amorphous Polyalphaolefin, which is also known as APAO, is a polymer of polypropylene. It has extensive uses as adhesive and was discovered during polypropylene production, and it came as a by-product of the process. It is a hot melt adhesive. Let’s take a look at the properties and applications of APAO hot melt adhesive.

Hot melt (HM) adhesives are solid materials at room temperature, and heat melts 100% solids without dissolving or dispersing them into a liquid phase adhesive used. HM adhesives are solvent-based or water-dispersible adhesives. It is eco-friendly as it does not require a drying process and requires more miniature workspace. It is necessary and has the characteristics of fast bonding speed. High-speed adhesion enables automation. Through this, it is possible to improve productivity and reduce labor costs. In addition, HM adhesion can adhere to a wide range of materials, such as packaging, bookbinding, woodworking, textiles, etc. It is used in several fields. Recently, automobiles and electrical and electronic fields are also attracting significant attention in high value-added industries.

There is a difference between an ideal adhesive and an industrially usable adhesive. There are adhesive polyamide, polyester, and polyurethane-based APAO hot melts. The chemical agent has a relatively low melt viscosity, a fast solidification time, and excellent adhesion. On the other hand, polyols such as ethylene-vinyl acetate, polyethylene, polypropylene, etc. Repin-based adhesives generally have high viscosity, long solidification time, and low adhesive strength.

Despite these shortcomings, olefin-based adhesives are the most popular among HM adhesives. It is used a lot. The reason is that the amount used per area of ​​the bonding area is different. Although there are many problems, the cost burden is relatively low, and the adhesive strength is not required. Because it can be applied in various fields. However, heat resistance is necessary if you choose a cheap adhesive because it is reasonable in the field product does not function properly due to low quality, or the producer has a high defect rate more significant economic burden.

Therefore, the quality requirements of the designed product are necessary to select an adhesive that meets the needs and has a reasonable price.

Polyolefin/polyamide blend as an HM adhesive that combines performance and price produce blended adhesives such as polyolefin/polyester blends. It can be cut. However, macromolecules with molecular weights ranging from thousands to tens of thousands due to the characteristics of the polymer to be used, the polyolefin is not miscible with polyester, so it is necessary for simple physical mixing. It is difficult to obtain a single property. Therefore, from a practical point of view, appropriate commercialization technology controls the dispersed phase’s size and improves the interfacial adhesion between the matrix and the domain should be improved. Commercially available technologies include reactivity that can react with some or all of the components. Addition of compatibilizer to induce graft reaction under high temperature and high shear force. Phases of immiscible blends using 6-12 compatibilizers. Improving solubility means morphological changes and systemic changes due to the decrease in interfacial tension. It represents an increase in surface adhesion. In the case of physical commercialization.
