As a new type of rubber and plastic material, thermoplastic elastomer TPE has been widely used in various industries in recent years. Some of these industries, such as food packaging industry, medical equipment industry, automotive interior decoration industry, etc., put forward more stringent requirements on the smell of TPE materials.
So, does the thermoplastic elastomer TPE have any smell, if so, where does the smell come from, and how to eliminate or reduce the smell of TPE materials? Below, the author will analyze and answer for you one by one.
1. Does 1.TPE smell
Air is odorless, but polluted air will also have flavor. TPE, as a composite polymer material, contains a variety of components such as rubber substrate, operating oil, compatilizer, other additives, etc. Even though the raw materials are carefully selected, it is unrealistic to do without any odor. In most cases, a little smell is acceptable to users.
2. How does 2.TPE smell come from
TPE, as a composite material, contains many components. Odors that may be generated are generally low molecular substances, such as white oil, compatilizers and other additives. This kind of auxiliary agent is easy to volatilize and release odorous substances in the process of TPE high-grade processing and synthesis, and if this kind of substances are not fully volatilized, TPE particles are packaged and packaged, then the residual odor cannot be released, and TPE inevitably has odor. Different quality of TPE raw materials results in different odor sizes of TPE finished products.
3. How to eliminate or reduce the smell of TPE materials.
One is to use high quality raw materials to mix them into TPE.
The second is to strengthen the treatment of volatile substances in the production process.
The application of TPE in automobile interior decoration is a growth point in the market in recent years. As a relatively independent enclosed space, the car has strict requirements for the smell of materials in the car. It is worth mentioning that the standards for odor testing are different for each automobile host manufacturer. The following are the odor testing and evaluation criteria for automotive interior trim parts by major host manufacturers!
