Plasticizers are non-volatile chemical solvents used throughout the plastics industry to increase such properties as flexibility, pliability, durability, longevity, biodegradability, and extensibility in polymers. When added to a plastic or elastomer, plasticizers affect the properties of the material without fundamentally changing its basic chemical makeup. It also helps to improve a product’s elastic modulus upon completion. By modifying the type or amount of plasticizer, properties can be tailored to meet requirements like high tensile strength or even soften the material. Read more >
Weather-resistant plastics have superior durability suited for extensive outdoor applications. These plastics have been widely adopted over the past century. The development of weather-resistant plastics has been one of the major innovations in material science, supplanting traditional materials like metal, glass, wood, and cotton. The appeal of many plastics stems from their better resistance to environmental degradation over time. The wide variety of material properties of plastics make them exceptionally adaptive for many different applications. It’s also safe for humans and is cost-effective. Read more >
The primary challenge in distinguishing an elastomer vs. polymer is that elastomers are a subset of polymers. When you hear the word ‘elastomer,’ think ‘elastic,’ for the term is in fact derived from ‘elastic polymer.’ The elasticity of elastomers is a good reason why this particular polymer is often used interchangeably with the word, ‘rubber.’ Nevertheless, an elastomer is a polymer with viscoelasticity, having properties of both viscosity and elasticity.

The manufacturing of plastic parts and products is an integral part of the global economy. A variety of plastic fabrication methods are performed to manufacture components for every industrial sector—medical and pharmaceutical, aerospace, shipping and packaging, electronics and electrical, automotive, transportation, durable goods and household items, construction, heavy equipment, agriculture, and so much more.
There are many types of plastic molding and methods used in manufacturing. Which plastic fabrication method is used depends on such factors as the product or part itself, its application, its size and shape, whether it requires thermoset or thermoplastic material, or high or low volume production rates. The following five plastic fabrication methods offer examples of the different kinds of plastic molding used for different manufacturing processes. Read more >
High heat resistance is one of the defining properties of high-performance plastics known as thermosets. Long touted for their light-weight and chemical-resistant properties, it is the high heat-resistance that makes the performance of thermoset plastics exceptional in demanding applications and environments.
Why Thermosets are the Best Temperature-Resistant Plastics
Several decades ago, the thermoplastics in use held promise as an inexpensive alternative, if not substitute, for metal, wood, or glass. Effective as the thermoplastics were, environmental factors like heat caused thermal degradation and wear. Though much lighter, the older-generation polymers could not provide the heat resistance that ceramics and metals could. Under high temperature conditions their performance was, overall, ineffective. The advance of thermoset plastics in the 1990s overcame these restraints, providing a higher degree of reliability, durability, and performance than the older polymers could. Read more >
Regarding the manufacturing costs of plastic parts, it is often noted that thermoplastic prices are lower than thermoset plastics. While this may be true to a certain degree, thermoplastics offer limited advantages when compared to their thermoset plastic counterparts. Upfront tooling costs, part strength and performance, and even appearance play an important part in determining which materials to choose, and although cost is a factor, it’s not the only one to take into account when determining which process to utilize. When it comes to material costs, without a doubt there are some key advantages to consider in using one type of plastic over the other. Upfront costs for thermoset materials are generally greater than thermoplastic, and the process takes longer to complete. Thermoplastic has the potential for rapid, high-volume production if needed. However, there are still limits to this advantage, and it’s more than just in the material costs, production time, or the many applications of either thermosetting plastics or thermoplastics. So, let’s look at the factors of thermoplastic and thermoset plastic manufacturing and some of their associated costs. Read more >
Thermoset plastic is a synthetic polymer known for its resilience, strength and durability. It is how thermoset plastics are made and manufactured that make it an ideal material for a variety of applications across many industries. Automotive, aerospace, construction, medical, military, agriculture, and corrosion control are all such industries that utilize parts made with thermoset plastic. Read more >
The usefulness of gel coating vs. paint for thermoset plastic parts is relative to the applications, needs, and requirements of the specific part. Gel coating is ideal and cost-effective for products produced via Resin Transfer Molding, because throughput is reduced when compared to a secondary painting process. However, if a part requires multiple colors or has a texture requirement, painting is a better alternative to gel coating. There are pros and cons to each. Here are a few for consideration.

In the world of material sciences and plastics, the difference between monomer vs polymer is often confused, if not confusing. Because the terms relate to plastic, they are seen in the broader, wider range of malleable synthetic or semi-synthetic organic compounds that are molded into solid objects. Nevertheless, synthetic monomers and polymers played a significant role in the history of plastics, revolutionizing material sciences in the early twentieth century and consequently emerging to play a prominent role in the modern industrial economy. The ability of chemists to engineer synthetic molecules to achieve a desired set of properties such as electrical conductivity, heat resistance, impact resistance, strength, stiffness, and density changed the world.
