The difference between pc7 and pc58 plastic cups

1. Different materials The material of the PC58 plastic cup is polycarbonate (PC), while the material of the PC7 plastic cup is acrylonitrile styrene resin (AS).

2. Personally, I think that pc7 is better. 1 The materials are different. The pc58 plastic cup is polycarbonate, and the pc7 is acrylonitrile-styrene resin. Different uses. PC58 is commonly used in kettles, space cups, and milk bottles. Department stores often use water cups made of this material as gifts. PC7 is used in pots, cups, milk bottles, etc. It is safe and resistant to drops, but it is not resistant to high temperatures.

3. Material difference: Number 7: Represents polycarbonate material. This material may precipitate bisphenol A at high temperatures. Long-term exposure poses a cancer risk, especially when exposed to infants and young children, which may lead to precocious puberty. Number 58: means that the polycarbonate content in the raw materials for making the cup is less than 58%. Although it meets certain health standards, it is also not resistant to high temperatures and easily releases the toxic substance bisphenol A when heated or in an acid or alkaline environment.

Who knows what cup pc58 means?

The PC58 logo on the cup means that the cup is made of PC (polycarbonate) material, and its material number is 58. PC Material Introduction PC (Polycarbonate) is a thermoplastic. Because of its excellent transparency, high strength, impact resistance and good processing properties, it is widely used in the manufacture of various products, including water cups, eyeglass lenses, CDs and DVDs.

The plastic cup bottom triangle 58 refers to the material of PC. The Chinese name is polycarbonate, and its use temperature is-20 ℃ to 120 ℃. This material is used for the space cup to ensure the safety of the cup. 58 That is to say, the polycarbonate content in the raw materials of the cup is less than 58%, so it can be filled with water or beverage with confidence and can be used normally without causing harm to human health.

The meaning of the number 58 in PC58: The "58" in PC58 means that the polycarbonate content in the raw material for making the cup is less than 58%. This means that the plastic cup is not made entirely of polycarbonate, but is mixed with other materials. This design may be designed to balance multiple factors such as cost, performance and safety. Safety of PC58 plastic cups: PC58 plastic cups meet health standards and can be used as cups.

Water cup PC58 refers to a water cup made of polycarbonate (PC) material. This material has excellent physical properties such as high temperature resistance, low temperature resistance, corrosion resistance, and wear resistance, thus giving the water cup PC58 excellent durability and safety performance. In addition, the water cup has the characteristics of non-slip, leak-proof, heat insulation, etc., and is suitable for various occasions, such as outdoor travel, sports and fitness, office and leisure, etc.

PC stands for polycarbonate. PC58 means that the polycarbonate content of the cup making raw materials is less than 58%. It meets health standards and can be used as a teacup.

Which is better, pc58 or pc7

The pure water barrel material of PC7 is relatively better. The following is a specific comparison of the materials of PC7 and PC58 purified water barrel: Material differences: PC58 is made of polycarbonate, while PC7 is made of acrylonitrile styrene resin. There are differences in chemical structure and properties between these two materials. Safety: PC58 material can easily release the toxic substance bisphenol A when heated or in an acid or alkaline environment, which may pose a risk to users 'health.

If you pay attention to the drop resistance of the product, PC7 has certain advantages; if it is a regular portable drinking water scene, PC58 is more common.

Personally, I think that PC7 is better. 1 The material is different. The PC58 plastic cup is polycarbonate, and the PC7 is acrylonitrile-styrene resin. Different uses. PC58 is commonly used in kettles, space cups, and milk bottles. Department stores often use water cups made of this material as gifts. PC7 is used in pots, cups, milk bottles, etc. It is safe and resistant to drops, but it is not resistant to high temperatures.

Is the pc58 water cup safe?

1. Safety. According to a query on Baidu Encyclopedia, PC58 is an amorphous, odorless, non-toxic, transparent thermoplastic plastic polymer. It is impact-resistant and has good toughness. It can withstand liquid temperatures of-20 to +120 degrees. It is suitable for filling and filling boiling water. However, it should be noted that if the PC58 water cup is exposed to high temperature, acidic or alkaline substances for a long time, harmful substances will be released and will affect human health.

2. PC58 water cups pose safety hazards. First of all, the safety of the PC58 water cup is not absolute. PC58 represents that the polycarbonate (PC) content in the raw material for making the cup is 58%. This material itself is amorphous, odorless, non-toxic, transparent and impact-resistant, and can withstand a wide temperature range., from-20 to +120 degrees. Under normal use conditions, such as filling warm or cold water, the PC58 water cup is relatively safe.

3. The plastic cup bottom triangle 58 refers to the material of PC. The Chinese name is polycarbonate, and its use temperature is-20 ℃ to 120 ℃. This material is used for the space cup to ensure the safety of the cup. 58 That is to say, the polycarbonate content in the raw materials of the cup is less than 58%, so it can be filled with water or beverage with confidence and can be used normally without causing harm to human health.

4. Deformation or cracks: If the water cup has been deformed or cracked, use it with caution, because these damages are prone to bacteria and may accelerate the release of harmful chemicals. Usage suggestions: Avoid high temperatures: Try to avoid using PC58 plastic water cups to store hot water and beverages, especially when heated in a microwave oven. Regular inspection: Regularly check the condition of the water cup and eliminate aging or worn water cups in time.

5. Alternative material options: Safer options include PP material (resistant to 130 ° C temperatures), Tritan material (free of bisphenol A and resistant to high temperatures), glass or stainless steel cups. These materials are more chemically stable at high temperatures and are not easy to release harmful substances. Optimization of usage scenarios: PC58 cups are more suitable for holding room temperature or low-temperature liquids (such as cold water and juice) and avoid being used in high-temperature scenarios such as making tea and coffee.
