Does PET masterbatch safe to make plastic product in plastics industry ?

We all know, masterbatch are made from primary plastic, premium pigments and plastic additives. Each type of plastic will have different physical properties and chemical properties. In this article, EuP will introduce you to how PET masterbatch are applied in the production of plastic bottles.

Are PET masterbatch chemically stable at high temperatures?

It can be said that PET masterbatch are chemically stable at high temperatures (when heated at a temperature of 50 degrees C or cooled at minus 90 degrees Celsius. Good masterbatch capacity, waterproofing gas ( O2 and CO2 are much better than other types of plastics High mechanical strength, high resistance to abrasion and good firmness The product is usually made of transparent, smooth and soft surface. to easily print logo and labels.

However, if the PET color is too high (over 100 degrees Celsius), it will produce aldehyde and antimony. In antimony, there are only 2 groups: group 2B is the group that causes cancer in humans, the rest is group 3 that is not toxic in humans. This resin is used only once and should not be recycled because of the low regeneration rate (only about 20%). According to the researchers, it is recommended to recycle PET plastic at temperatures below 40 degrees C for less than 10 days and then replace it completely.

In addition to plastic bottles, which PET masterbatch are applied in?

PET masterbatch are most commonly used to make water bottles, cooking oil bottles, soft drink bottles, sometimes dishwashing liquid bottles. The reason is probably because of the cost at production stage as well as the low recycling capacity of this plastic. In addition, this material is also widely used in the production of plastic food trays, manual yarn production in the textile and bags industries. In short, PET masterbatch in plastic bottle application should only be used for a short time before replacing them.
