Thermoplastics are any plastic polymer substance that becomes malleable or moldable at a specific elevated temperature and solidifies upon cooling. Thermoplastics encompass all plastic materials that soften and may return to a liquid state when heated but solidify and become rigid when cooled. Read More…

Thermoplastic Polymers Properties

Typically, polymers are chosen to replace metal in structural applications. However, a like-for-like substitution of a polymer component for a metallic section will often reduce weight.

Polymers can be easily molded into shapes where metals are challenging. The engineer can create a desirable shape that facilitates plastic forming, reduce cost and weight, and improve aesthetics by employing a polymer. Since the polymer portion does not need painting for corrosion protection, like the similar metal part, further cost savings is realized. The choice of a particular polymer will depend on the end-use environment's temperature, chemical composition, and mechanical needs.

Polymerization Process

The process of polymerization is used to connect monomers, or tiny molecules, to create long chains to create thermoplastics. Many thousands of monomers can be used to create a single polymer chain. While there are weak forces between chains, strong covalent bonds connect the atoms in polymer chains.

Side branches may be present in polymer chains depending on the kind of monomer. A polymer chain can form organized; crystalline areas known as spherulites only contain a few short side branches. On the other hand, the polymer is amorphous if the chain has numerous big side branches since this prevents the formation of organized regions.

Amorphous polymers include acrylonitrile-butadiene-styrene (ABS), polyvinyl chloride (PVC), and polystyrene (PS) (ABS). Since crystallites deflect light, amorphous polymers are employed in applications where optical clarity is essential. However, these amorphous polymers lack a crystalline structure and are less resilient to chemical assault and environmental stress cracking.

Before a thermoplastic polymer can be utilized, it is typically combined with additives to enhance its functionality, stability, or appearance. Additives may include stabilizers, plasticizers, lubricants, flame retardants, and colorants. Stabilizers are added, for instance, to lessen deterioration brought on by heat or sunlight. At the same time, plasticizers are used to make amorphous chain segments more mobile, lowering the glass transition temperature and reducing brittleness.

Amorphous and Semi-Crystalline

Types of Thermoplastics

The majority of thermoplastics are made from polymeric resins. These are extended chains of several smaller monomers joined by covalent bonds. Condensation polymers and addition polymers are the two primary categories of thermoplastics. Plastics that create covalent connections without losing atoms or molecules are classified as extra polymers. On the other hand, during bonding, condensation polymers consistently lose a molecule, typically water.

Based on their chemical makeup and how they form bonds, the materials within these classifications can be divided into monomers, intermediates, binders, base polymers, elastomers, and rubber materials. The unique characteristics of thermoplastics might further categorize them. To improve or change the properties of plastic material, thermoplastic makers can add additives like powders, fibers, plasticizers, and ceramics in addition to the polymerized ingredients. These are crucial in the manufacture and processing of thermoplastics.

Considerations When Purchasing Thermoplastics

Thermoplastics come in a wide range of densities and crystalline structures, and they all have unique features. Therefore, understanding a plastic's specifications concerning the finished product or application is crucial. The correct thermoplastic for a given application depends on various criteria, including additives, manufacturing, and raw material availability. Physical, mechanical, electrical, and optical characteristics, as well as melting point, size, and flexibility, are additional factors.

When considering any thermoplastic, one must specifically consider the following factors.

  • The resin viscosity needs to be low enough to penetrate the reinforcement.
  • The size of the molding: Because cure reactions are sometimes exothermic, thick moldings may require a slower rate of curvature to prevent an uncontrolled temperature rise during the curing process, which could be enough to harm the molding.
  • The speed of reaction plays a significant role in the volume of articles produced.
  • The resin needs to moisten and stick to the reinforcement to be compatible.
  • Moisture content: Some polymers do not perform as well as others in wet conditions. Ingress of moisture into a laminate might result in a serious loss of characteristics.
