In today's plastics industry, ABS plastics have attracted much attention for their excellent performance and wide range of applications. However, people often have some doubts and misunderstandings about the heat-resistant temperature of ABS plastics. This article will reveal the heat resistance of ABS plastics and answer the question of whether it can withstand the test of high temperature.
1、 Basic characteristics of ABS plastics
ABS plastic is a copolymer of acrylonitrile, butadiene and styrene, which has excellent mechanical properties, impact resistance and chemical resistance. It has good processing properties, and can be made into products of various shapes through injection molding, extrusion, blow molding and other processes. Therefore, ABS plastics are widely used in household appliances, automobiles, electronic products and other fields.
2、 Heat resistance of ABS plastics
The heat resistance of ABS plastic mainly depends on its glass transition temperature (Tg). The glass transition temperature refers to the temperature at which the plastic changes from glass state to rubber state, and also the temperature at which the plastic begins to soften. The glass transition temperature of ABS plastic is generally about 85 ℃, so under normal temperature, ABS plastic has good rigidity and strength.
However, when the temperature exceeds the glass transition temperature of ABS plastics, their properties will change significantly. Under high temperature environment, ABS plastic will become soft and lose its original rigidity and strength. Therefore, when ABS plastic products are used at high temperature, it is necessary to consider whether their heat resistance can meet the demand.
3、 High temperature application of ABS plastics
Although the heat resistance of ABS plastics has certain limitations, it can still play its advantages in some specific application fields. For example, ABS plastic is often used in the field of household appliances to make high-temperature resistant products such as electric kettle and electric rice cooker. In addition, in the automotive field, ABS plastic is also widely used in engine hood, body parts and other components that need high temperature resistance.
4、 How to improve the heat resistance of ABS plastics
If ABS plastic needs to be used at higher temperature, its heat resistance can be improved by adding reinforcing agent or changing the proportion of copolymer. For example, glass fiber reinforcement can be added to increase the rigidity and heat resistance of ABS plastics. In addition, the heat resistance of ABS plastic can be improved by changing the proportion of copolymer and increasing the content of acrylonitrile monomer.
ABS plastic has certain limitations in heat resistance, and its heat resistance temperature is generally about 85 ℃. Under high temperature environment, ABS plastic will become soft and lose its original rigidity and strength. However, in some specific application fields, ABS plastics can still play its advantages, such as home appliances and automobiles. If ABS plastic needs to be used at higher temperature, its heat resistance can be improved by adding reinforcing agent or changing the proportion of copolymer.
