tpe plastic raw material characteristics. TPE raw materials are believed that thermoplastic elastomers made of SEBS as a base material and other additives are collectively called TPE raw materials. To know the characteristics of TPE raw materials, first understand the characteristics of SEBS.
SEBS has excellent aging resistance, which is both plastic and highly elastic, and can be processed and used without vulcanization. The scraps can be reused. The performance degradation rate of aging in the artificially accelerated aging box for one week is less than 10%, and the performance degradation rate of ozone aging (38℃) for 100 hours is less than 10%. Widely used to produce high-end elastomers, plastic modified , adhesives, lubricating oil tackifiers, fillers and sheath materials for wires and cables.
has good temperature resistance, its embrittlement temperature is less than -60℃, the maximum service temperature reaches 149℃, and its decomposition temperature is greater than 270℃ under the atmosphere of oxygen . Good weather resistance, heat resistance, compression deformation resistance and excellent mechanical properties.
has good solubility, blending performance and excellent oil filling properties. It can be dissolved in many commonly used solvents. Its solubility parameters are between 7.2-9.6, and can be blended with a variety of polymers. It can be filled with oils commonly used in the rubber industry, such as white oil or cycloane oil . Excellent electrical properties, its dielectric constant is between 1 kilohertzhm and megahertz;
has good ultraviolet stability, antioxidant and thermal stability, so it can also be used in roofs and road construction asphalt .
Elastomer that can be used without vulcanization. Its processing performance is similar to SBS. The scraps can be reused, meet environmental protection requirements, are non-toxic, and meet FDA requirements. SEBS has a light specific gravity of about 0.91, and the same weight can produce more volumes of products.
TPEPlastic raw materialHighlights characteristics have so many advantages. Any material must have its disadvantages. The biggest disadvantage of TPE raw materials is that they are not resistant to high temperatures. Usually, the temperature resistance of TPE is around 80-100 degrees. Users must pay special attention to your product application scenarios. For more characteristics of TPE plastic raw materials, please consult Lien TPE manufacturer.
