T/T: A telegraphic transfer (T/T) is an electronic method of transferring funds utilized primarily for overseas wire transactions. Telegraphic transfers are also known as telex transfers, abbreviated T/T; T/Ts can also refer to other types of transfers.
L/C: An L/C at sight is a letter of credit (L/C) that is payable immediately – within five to ten days – after the seller meets the requirements of the letter of credit.

What is PC resin?
PC plastic stands for Polycarbonate, the English name is written as Polycarbonate, so the abbreviation is PC. It is a colorless and transparent amorphous thermoplastic.
Physical properties of PC resins include: specific gravity: 1.18-1.20 g / cm3; shrinkage of mold: 0.5-0.8%; casting temperature: 230-320 ° C; Drying conditions: 110-120 ° C, can also be -60 ~ 120 ° C. Very durable should be used for long time.
- High impact resistance, colorless and transparent, High hardness, so the size and color stability, electrical insulation, corrosion resistance and abrasion resistance are relatively high.
- Tend to crack during impact, high temperature is easy to hydrolyze, less compatible with other resins.
- Amorphous material, good thermal stability, wide range of temperature formation and poor fluidity. Low moisture absorption, but sensitive to water, must be dried.
- The mold shrinkage rate is small, and brittle when in high pressure environment.
- High melting point, quick cooling, high impact intensity, low bend.
Because of these characteristics, PC plastic is often used in kettles, space glasses, and bottles. Sometimes you'll see numbers on the cup, such as 58, which means the polycarbonate content of the cup is 58%.
- Resistant to strong impact.
- Easy to process and polish.
- Easy to heal.
- Good electrical insulation.
- Higher heat resistance than PETG plastic.
PC plastic is used for doors, chutes / slides, sockets, plugs, transparent working models, shields, eyeglasses, guards, etc.
The PC itself is not toxic, but it contains bisphenol A, the toxic substance. In theory, as long as Bisphenol A is converted into a flexible structure during PC production, it means that the product is completely free of bisphenol A. However, if during production, Bisphenol A is converted converted into PC material, if the conversion is incomplete and a small amount of bisphenol A is not converted into the plastic structure of the PC, it can transform carcinogens.
In general, for short-term use, harmful substances will not be dispersed, such as instant, disposable mineral water bottles.
However, if hot water or residual slime is added when using a PC plastic box, harmful substances will be released, harmful to the human body. Therefore, to prevent the dissolution of harmful substances in the PC, please do not use the PC cup to keep hot water but instead only use cold water or warm water.
At the same time, when using a plastic box, the food should be strictly stored according to instructions, properly stored and disinfected, to avoid the repeated use of aging or damaged PC products.
After reading the explanation of Sunwell Vina, can you rest assured? Do you think PC plastic is an angel or devil? In fact, there are both positive and negative things. There are so many such examples in life. We will have no problem if we use them correctly and do not overdo it.
