Brief analysis of electronic adhesives for bonding ABS plastics


ABS material is a common thermoplastic, mainly composed of three polymers: acrylonitrile (A), butadiene (B), and styrene (S). ABS material has excellent mechanical properties, impact resistance and heat resistance, and is widely used in home appliances, automobiles, toys and other fields. In the processing and manufacturing of ABS materials, electronic adhesives are often used for bonding. So, what electronic adhesives are used to bond ABS materials?

First of all, it must be clear that the surface calendering treatment of ABS material is essential, which can improve its adhesion. But when choosing electronic adhesives, we also need to consider the following two factors:

Electronic adhesive ingredients

Currently, there are many types of electronic adhesives on the market, and different types of glue have different compositions. Therefore, it is necessary to choose the appropriate electronic adhesive according to the characteristics of the ABS material. Among them, commonly used electronic adhesive ingredients include epoxy resin, polyurethane, silicone, etc.

Epoxy resin electronic adhesive: Epoxy resin electronic adhesive has strong adhesion and shear resistance, good thermosetting properties, and long service life. It has certain applicability for the bonding of various materials, especially in the bonding of metals, plastics and other materials. However, due to its high hardness, it may affect the ABS material.

Polyurethane electronic adhesive: Polyurethane electronic adhesive has excellent elasticity, shock resistance and mechanical properties. It is colorless and transparent in the air and has a good bonding effect on ABS materials. However, due to its strong yellowing property, you need to pay attention to its possible impact on light-colored ABS materials.

Silicone electronic adhesive: Silicone electronic adhesive has good sealing and bonding properties, excellent temperature resistance and insulation, and is often used for bonding ABS materials and other plastic materials. However, it has good elasticity and can withstand large deformation stress, which may cause deformation and damage of the ABS material. When using silicone electronic adhesive to bond ABS materials, the appropriate silicone must be selected according to the hardness and strength of the ABS material. Electronic adhesive, giving it good adhesion and appropriate elasticity.

Operating environment and working temperature

Operating environment and operating temperature are important factors in selecting the appropriate electronic adhesive. First of all, the operating environment should be as dry and oil-free as possible, and necessary processing work should be carried out to ensure the adhesion effect of the electronic adhesive. Secondly, ABS materials need to choose electronic adhesives that can be bonded within the working temperature range. This is because temperature also has a great impact on the adhesive force of the glue.
