Pet Vankai (polyethylene terephthalate 821)
Wankai PET is one of the most suitable polymer materials for the production of bottles and preforms, which is sold under this brand in China. It is a unique grade of PET (thermoplastic polymer). This product is imported and sold at an affordable price.
Polyethylene terephthalate (PET) is a general purpose thermoplastic polymer that belongs to the polyester family. Polyester resins are known for their excellent combination of properties such as mechanical, thermal, chemical resistance as well as dimensional stability.
The main customers of this product are producers of carbonated soft drinks and carbonated drinks. Providing quality products to the consumer has always been our priority, so to have a higher level of quality and service in the product for production, contact Pedidan Polymer.
Features of Pet Vankai (polyethylene terephthalate 821)
This grade of PET has excellent characteristics, including the very high transparency of this polymer, and this polymer can be used to package products that want to be displayed.
This product has a very high resistance to pressure and impact, which is the feature that has made the producers of carbonated drinks able to use this product for their packaging.
Another very good feature of this product is that they can be recycled. that this product is recycled and compatible with the environment.
Applications of polyethylene terephthalate 821
PET/PET bottles currently represent the most important application of PET molding resins. The manufacture of PET bottles starts with raw materials: ethylene and paraxylene. Derivatives of these two substances (ethylene glycol and terephthalic acid) react to obtain PET resin. This resin is melted into small cylinders called pellets and injected into a mold to make a preform.
A preform—a type of test tube, shorter than the final bottle but with thicker walls—is molded. During the blow molding step, high-pressure air is blown into the preform, allowing it to take the exact shape of the mold it is placed into. The final product, thanks to the molecular structure of the material, is a transparent, unbreakable, sealable and lightweight bottle.
It is the strength of the material that contributes to the success of PET. In fact, carbonated soft drinks can create up to 6 times the pressure inside the bottle. However, such a high pressure is not able to change the shape of the bottle and cannot explode the bottle, thanks to the alignment of the macromolecules (crystallization) that occurs both during the resin spinning process and the blow molding process. Another advantage of this material lies in its physical properties, which provide great freedom in design.
Over the years, the PET industry has increasingly addressed environmental concerns and significantly reduced the amount of raw materials needed to make bottles. Today, a 1.5-liter PET container is produced with only 35 grams of raw materials.
Another notable environmental feature of PET is that it is fully recyclable. In 1977, the first PET bottle was recycled and turned into a bottle base cup. However, the fiber industry soon discovered the “new” material source and began using it to make textiles, carpets, and nonwovens. Today, although the “bottle-to-bottle” recycling process is growing, the fiber market is still the main output of recycled PET.
