Types of Polymers Compounded to Your Specifications

A polymer is a compound made of repeating units of monomers. Polymers Compounded are useful for making plastics and other items. These compounds can be natural or synthetic. They may have two or more monomers, and may be linear, branched, cross-linked, or sheet-like in nature. The process used to create a polymer is known as polymerization. Typically, synthetic polymers are not found in nature. Examples of polymers that are synthetic are plastics, rubber, and silicones.

Synthetic polymers

A wide variety of synthetic polymers can be made to meet your exact specifications. Many of these polymers can be used as drug carriers. One of the most popular and versatile synthetic polymers is the polyaspartamide. Polyaspartamides are created through a process called aqueous phase Michael addition polymerization. It involves two monomers with two activated vinyl groups and one primary amine. The polymer is then formed by reacting these monomers with water.

Synthetic polymers are often mixed with other ingredients to create composites. Once the compound is created, it is heated to soften and melt, and then it is shaped to your specifications. The resulting material is usually a shape-retaining compound that will keep its shape throughout its service life. Each synthetic polymer has its own characteristic melting temperature and range, and this temperature is important in determining its operating temperature and chemical resistance.

Natural polymers

Natural polymers are a class of substances composed of a mixture of several different chemical units. Each is a multiple of the simplest chemical unit, the monomer. Polymers are found in many different natural and synthetic materials. For example, proteins and cellulose are polymers. In addition, they are the basis of glass, paper, plastics, and minerals.

The polymers we commonly use everyday include plastics, rubbers, and fibers. In addition to these familiar materials, natural polymers include many bio-based materials. For example, the biopolymer alginate is used in food, packaging, and biomedical engineering. Alginate was originally used as a wound dressing, but is now used for a wide range of applications. Because its density and fibrous structure allow for control over drug release, it is also used in pharmaceutical applications.

Semi-inorganic polymers

Semi-inorganic polymers are a class of compounded materials that are entirely or partially inorganic. These materials can have varying physical and chemical properties. Many are thermally stable and have low toxicity. They can also be customized to meet your specific requirements. You can choose to modify the side groups, molecular weight, and cross-link density to achieve the desired results.

Inorganic polymers are made from a non-carbon backbone. This means that the molecules are not bonded with hydrogen or other organic side groups. However, some inorganic polymers contain side chains or pendant groups that are bonded to carbon in the main chain. Inorganic polymers have various beneficial properties.

Polysilazanes are a class of inorganic polymers with a silicon-nitrogen bond backbone. They may be crystalline, highly rigid, or completely amorphous. The advantages of this type of polymer are that they are easy to process and contain low amounts of energy. In addition, they are highly heat resistant and do not hydrolyze. However, if they are exposed to UV light, they degrade. In addition to their excellent physical properties, these materials can be used in a variety of applications.

Thermoplastic elastomers

Thermoplastic elastomer compounding involves blending melt plastics with additives to change the physical, electrical, and aesthetic properties. These thermoplastics are lightweight, chemically resistant, and have low melting points. They are also good electrical insulators and resist abrasion.

The tensile properties of elastomers describe their ability to withstand a specified amount of strain before breaking. Thermoplastic elastomer testing is typically performed in two directions, and the units are pounds per square inch (psi) and megaPascals (MPa). The higher the tensile property, the harder it is to break.

The abrasion resistance of an elastomer depends on its molecular structure. Elastomers with high abrasion resistance can withstand friction and rough surfaces. Standard abrasion tests involve fixed force on a rubber sample, which does not reflect real-world conditions. Furthermore, abrasion resistance and tensile strength are not necessarily related to each other.

TPEs are the fastest growing synthetic polymers. They can substitute for many generic polymers, including ethylene styrene-block copolymers and propylene rubbers. Their unique properties make them excellent impact modifiers for plastics and provide a unique performance application for compounded products. These compounds are UV-resistant, resistant to acids, and have good abrasion and heat stability.


Fluorocarbons are highly reactive organic compounds with water and stain-repellent properties. These compounds were previously used in Scotchgard and Teflon products, though many of those products have since been phased out, due to environmental concerns. These materials are also used in precision plastics and fishing line.

These compounds are colorless, and have high density – nearly twice as dense as water. As a result, they are not miscible with most organic solvents or hydrocarbons. They are also poorly soluble in water, which results in low solubility.

The chemical formula for fluorocarbons is C2H3C3OH, and its boiling point is approximately -27 degC, compared to 55 degC for acetone. The corresponding hexafluoroacetone is a mixture of two hydrofluorocarbons or two perfluorocarbons. Typically, C-F is added as the solvent. This produces a stable hydrate, (CF3)2C(OH)2. Ammonia is used to dehydrate (CF3)2CNH, and it is also dehydrated with POCl3.

Rubber polymers

A rubber polymer compound is a blend of base polymers, fillers, and other chemicals. These ingredients are chosen to achieve optimal performance in a particular service. The process starts with selecting the correct type of polymer, and the compounder may add reinforcing agents, coloured pigments, or curing agents.

EPDM and its variants are versatile compounds with excellent mechanical and weathering properties. It is also good at low temperatures and has good flexibility. However, its resistance to oil is rather low, and it is typically used as a viscosity modifier in lubricants. EPDM is often blended with other elastomers, such as thermoplastic elastomers (TPV), to improve the properties of the final product.

AirBoss and its subsidiaries are committed to ethical sourcing of rubber compound materials. These standards are applied throughout the company, so you can be confident that your compound meets ESG requirements.

Structured polymers

Structured polymers are complex molecules that have a particular shape and have unique properties. They can be amorphous or crystalline and may contain fibers or inorganic materials. They are typically compounded with other polymers or additives, and are used in a variety of applications.

Compounding is a critical step in the manufacturing of polymer blends, and the right additive know-how can ensure that each material has the proper morphology and properties. PC is used in a wide range of applications, including the optical media market, sheeting and glazing, and electrical and electronic markets. Other applications include packaging, appliances, and transportation.

The materials can be made from natural or synthetic polymers. The former is the most popular, as it is extremely versatile and is often used in building materials. Synthetic polymers, on the other hand, can be manufactured to your exact specifications and are often used in the textile industry.

Molecular composites

The process for making a molten composite starts with the formulation of the polymer. The polymer is combined with the reinforcing particles and the resin. The result is a polymer that is biodegradable, recyclable, and high-performance. The fiber content is measured in percent of the composite weight and is expressed in centipoises (cps). Fibers are typically placed in the same direction, providing strength.

A polymer is a solid material with a low melting point and high molecular weight. The resin bonds with the reinforcement fibers, producing the desired performance characteristics. The resin is then transferred into a mold cavity. The resin may not be heated during the process. The mold is then closed or open. The polymer used to create the mold is usually an epoxy or silicone resin.

These materials can be made of a variety of materials. For instance, a polymer can be hydrophobic or hydrolytically degradable. This can be achieved by treating the reinforcing fibers. Additives can improve the physical properties of the composite, such as plasticizers, surfactants, and starch.
