They are classified either as thermosetting polymers or thermoplastic polymers. Spider silk, hair, and horn are protein polymers. Starch can be a polymer as is cellulose in wood. Rubber tree latex and cellulose have been used as raw material to make manufactured polymeric rubber and plastics. The first synthetic manufactured plastic was Bakelite, created in 1909 for telephone casing and electrical components. The term polymer is commonly used in the plastics and composites industry, often as a synonym for plastic or resin.
The most familiar plastic polymers including polyethylene (PE), polypropylene (PP), epoxy and polyester (PS) are derived from petroleum hydrocarbons. These materials are used in a diverse range of applications. However, they do pose an end-of-life recycling and disposal issue as they do not break down easily. Plastics and natural materials such as rubber or cellulose are composed of very large molecules called polymers. Polymers are constructed from relatively small molecular fragments known as monomers that are joined together.

EP division customizes This reaction is known as polymerization, the low-molecular compounds as " monomers," and the high-molecular-weight substance as a " high-molecular Lubrizol makes polymer ingredients that are used as rheology modifiers, efficient thickeners and Unlike solid plastic microbeads, Lubrizol's polymers are:. Aug 17, 2016 The Plastics Revolution: How Chemists Are Pushing Polymers to New Limits. Thermoplastic polymer consisting of long chains of the monomer Metal-containing polymers stand to benefit from the mechanical properties of polymers and the chemical properties of metals.

PET is also used in blends with other polymers, such as polycarbonate. Plastics. The word "plastic" is frequently used loosely as a synonym for "polymer," but the EP-Engineering Plastics. Engineering Plastics Division provides a portfolio of polymer compounds for applications in various industries.
In many plastic products, the polymer is only one constituent. In order to arrive at a set of properties appropriate to the product, the polymer is almost always combined with other ingredients, or additives, which are mixed in during processing and fabrication. Among these additives are plasticizers, colorants, reinforcements, and stabilizers. Polymer Plastics is dedicated to helping you meet your needs for high quality plastic products.
