How to identify the material of waterproof junction boxes

Is the material of the waterproof junction box ABS or PC?

Nowadays, these two materials are often mixed and different additives are often added to enhance product performance. Therefore, it is difficult to look at them solely from the appearance. If it is a relatively pure ABS and PC product, it can be simply distinguished by the rigidity of the product. Judging by the hardness of the junction box: ABS is relatively soft, but has good toughness; PC is hard, but relatively brittle. If you are not afraid of damage, you can also use a sharp object to scratch it. ABS is prone to marks, while PC is not.

What is the difference between engineering materials ABS+PC and PC+ABS? ABS+PC alloy refers to an alloy material with a majority of ABS components, such as ABS 80%+PC 20% alloy. Similarly, PC+ABS refers to an alloy material with a majority of PC materials, such as PC 80%+ABS20%. The characteristics of the alloy are mainly based on the material's characteristics, and the minority components are added to improve some shortcomings of the majority components Adding PC to ABS is to improve its impact resistance, etc ABS is cheaper than ABS+PC, with good impact resistance, slightly inferior heat resistance, poor weather resistance, and good glossiness.

ABS+PC material, as the name suggests, is an alloy that blends ABS and PC materials. Due to the advantages of PC material in impact resistance, high glossiness, natural fire resistance, and high heat resistance, the alloy materials of ABS and PC also inherit some of the characteristics of PC. Compared to ABS, it improves impact resistance, high glossiness, fire resistance, and heat resistance. But the price of PC+ABS is also quite expensive compared to ABS, and the specific choice needs to be determined by the customer's own needs.
