Thermoplastic vs. Thermoset Materials: The Essentials of Rubber Mixing and Molding

Share Article

Know the difference between thermoplastic and thermoset materials, which is a part of the process of rubber mixing and molding. AudioSolutionz is conducting a webinar on Thursday, October 29, 2015 where the essentials of rubber mixing and molding will be described.

The principal difference between both is that thermoplastics can be continuously re-melted when they are heated, however, thermosets cannot be.

With its wide range of application in various industries, such as electrical, automotive, medical, appliances etc. Rubber has a vast demand of approx. 15 billion kilogram every year. Its unique molecular structure and many useful properties provides the product ultimate elongation and good elastic recovery. Rubber is also very soft and flexible, maintains good chemical resistance and is very useful in wide temperature ranges.

It is thus important, that special care be given in rubber mixing and molding which would produce thermoset rubber compounds. In this context, it is important to understand the difference between thermoset and thermostatic materials, so that quality is not tampered with and the produced result remains of good quality. Most rubber compounds are thermosetting materials, and most plastics are thermoplastic. The principal difference between both is that thermoplastics can be continuously re-melted when they are heated, however, thermosets cannot be.

Thermoplastics are turned to finished molded parts by a way of injection molding. In contrast, imagine thermoset to be a cake mix, which once baked, can’t be reheated or unbaked. Once you have set up your thermoset material, further heating it will only deteriorate the quality of material and lose chemical and physical properties. There are similarities, when it comes to over-baking a cake. Most of the rubber compounds are thermosets, and these compounds are turned to finished molded parts by injection molding, compression or transfer. Generally, there are two available methods of molding thermosets and only one method of molding thermoplastic. The form of the material is the reason behind such a phenomenon.

There also are thermoplastic forms of rubber and thermoset forms of plastic. Polyurethane is one of such materials which is available in both thermosetting and thermoplastic forms. It needs a competent technical support team to deduce which is best suited for the particular design and application, after it analyses the whole scenario. Most plastics we encounter today are thermoplastics, while rubber compounds remain overwhelmingly thermosetting due to the nature of rubber application.

AudioSolutionz, country’s leading information provider is hosting an event ‘The Essentials of Rubber Mixing and Molding’ where expert speaker Jeffery A. Jansen on Thursday, October 29, 2015 will explain the process of formulating, molding and mixing needed to produce thermoset rubber compounds. It is important to understand the characteristics of rubber materials which, though often treated as a commodity, is a complex engineering material.
