Materials Science What does 100% PET mean? January 30, 2026 by pups | Leave a Comment 100% PET means the product is made entirely of polyethylene terephthalate (PET or PETE), a strong, stiff synthetic fiber and resin belonging to the polyester family of polymers. PET is valued for its strength, gas and liquid impermeability, and recyclability, making it suitable for various applications from textile fibers to food and beverage containers. What […] Read more »
Materials Science Is polyester just a PET? January 30, 2026 by pups | Leave a Comment Polyester is a category of synthetic polymers with a wide range of properties and applications. Polyethylene terephthalate (PET) is a specific type of polyester known for its strength and stiffness, commonly used in fibers and disposable beverage bottles. While PET is the most prominent member of the polyester family, not all polyesters are PET. What […] Read more »
Materials Science Which is better, PET or PP? January 30, 2026 by pups | Leave a Comment PET (polyethylene terephthalate) and PP (polypropylene) are both popular plastics, each offering unique properties that make them suitable for different applications. PET is known for its strength and transparency, while PP is valued for its chemical resistance and flexibility. Deciding which is "better" depends largely on the specific needs of the product or application. PET […] Read more »
Materials Science Which is more flexible, polyester or nylon? January 30, 2026 by pups | Leave a Comment Nylon is generally more flexible than polyester due to its molecular structure and properties. Nylon’s elasticity and ability to stretch make it suitable for applications requiring flexibility, while polyester is more rigid and better at maintaining its shape. Both are synthetic polymers with distinct characteristics that determine their best uses. Polyester vs. Nylon: Which Material […] Read more »
