1. How to distinguish whether the material of the waterproof junction box is ABS or PC? Nowadays, these two materials are often used in combination, and in order to enhance the performance of the product, different additives are often added, so it is difficult to look at it from the appearance. If it is a relatively pure ABS and PC product, you can easily distinguish it by the rigidity of the product. It is the hardness of the junction box to distinguish: ABS is relatively soft, but good toughness; PC is hard, but relatively brittle. If you are not afraid of damage, you can also use a sharp thing to scratch, the ABS is easy to trace, and the PC is not easy.
2. What is the difference between engineering materials ABS+PC and PC+ABS? ABS+PC alloy refers to the alloy material with the majority of ABS components, such as ABS 80%+PC 20% alloy. Similarly, PC+ABS refers to the alloy material with PC material, such as PC 80%+ABS20%, which component Most of the characteristics of this alloy are mainly based on the characteristics of this material. A small number of components are added to improve some of the shortcomings of most components. For example, ABS is added to improve the impact resistance of ABS. ABS price It is cheaper than ABS+PC, has good impact resistance, is slightly in heat resistance, has poor weather resistance and good gloss.
As the name suggests, ABS+PC materials are alloys of ABS and PC materials. Due to the impact resistance, high gloss, natural fire resistance and high heat resistance of PC materials, ABS and PC alloy materials also inherit the PC part. The characteristics, compared with ABS, improve the impact resistance, high gloss, fire resistance, heat resistance is also relatively improved. But the price of PC+ABS is also a lot more expensive than ABS. The specific choices need to be handled by customers own needs.
