PBT crystallizes faster than PET and remains crystalline. Also, while PET can be either in the semi-crystalline state or in the amorphous state, it is not possible under normal processing conditions to produce PBT parts that are amorphous. PBT differs only slightly from PET in chemical composition but more substantially in its properties such as its higher crystallization rate and lower melting point.
The key feature that makes two polymers distinctive is the use of alcohol resulting in ester group.
Polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) both belong to the polyester family. Let’s begin by comparing apples with apples. Also do not forget, PET is one of the most recycled thermoplastics as well.Īdditionally, there have been continuous efforts to tailor PET properties for improved performance with beneficial cost profiles to meet high-end application demands.Īt the same time, polypropylene, polyethylene and polyvinyl chloride are equally popular for these benefits, so how do you find which one is suited for you? In this guide, you will find out the key knowledge to find the suitable grade among thousands of options available. For all the applications demanding lightweight and impact-resistant material, PET is of your choice. You find the polymer used in packaging, fabrics, films to molded parts for automotive, electronics and many more. PET is among those plastics which are an important part of your everyday life. Most common application include rigid and flexible packaging as it is very light weight. It has a semi-crystalline form when stable. It is widely used in everyday items and easily recyclable. It has quite low permeability to gases and humidity increasing shelf-life of products.Polyethylene terephthalate or PET belongs to the family of polyesters. Due to high sustaining capability, it is ideal for storing carbonated products. It is unbreakable, tough and incredibly convenient for production and storage. It complies with most of the food materials and do not affect the physical appearance, taste or odor. Sparkling bottles with almost glass like finish can be produced using it. PET or PolyEthylene Terephthalate is a great material for producing pure, healthy and food grade containers. Since we are also manufacturer of outstanding quality bottles, Caps.
