Product Description

SEPS is a styrene-ethylene/butene-styrene block copolymer, which is a kind of thermoplastic elastomer rubber. It is a high-performance elastomer material with a unique molecular structure consisting of a hard segment (polystyrene) and a soft segment (ethylene/butene). This structure gives it both the elasticity of rubber and the processability of plastic.
Performance characteristics
Excellent elasticity: The elastic resilience of SEPS rubber is very strong, and it can quickly return to its original shape even after a large deformation. For example, in applications such as the manufacture of sole shoes, it can provide good shock absorption and resilience, so that people feel comfortable when walking or exercising.
Good temperature resistance: it can maintain its performance over a wide temperature range. Generally speaking, it can remain soft and elastic at low temperatures, and will not harden and become brittle at low temperatures like some ordinary rubber; It also has good stability at high temperatures and can withstand a certain degree of heat without serious deformation or performance degradation.
Chemical stability: Good tolerance to many chemicals. It can resist the erosion of chemical substances such as acid and alkali, and can maintain its own physical and chemical properties in some application scenarios where the chemical environment is more complex, such as auto parts and chemical equipment seals.
Strong machinability: As a thermoplastic elastomer, SEPS can be molded like plastic by injection molding, extrusion and other processing methods. Compared with the traditional vulcanized rubber processing method, this greatly improves the production efficiency, and can produce products with complex shapes. For example, when manufacturing some small sealing rubber parts, you can quickly and efficiently produce products that meet the requirements by precision injection molding.
Production method
SEPS are usually synthesized by anionic polymerization. In the reaction process, the organollithium reagent is used as the initiator to initiate the polymerization of styrene monomer to form polystyrene chain segment, and then the mixed ethylene/butene monomer is added for polymerization, and finally the styrene monomer is added to form block copolymer. This polymerization method can precisely control the molecular structure and molecular weight of the polymer, resulting in stable SEPS products.

Hardness: YH-4010 may have a specific hardness range, which has an important impact on the feel of the product and the application scenario. For example, if it is used to make some products that require some flexibility but not too soft, such as the handle of some tools, its hardness may be designed to meet the ergonomic range, allowing the user to hold comfortably, while ensuring the stability of the tool when used.
Tensile strength: It has a certain tensile strength index. Tensile strength represents the ability of a material to resist breaking when stretched. In practical applications, such as the manufacture of products with high tensile requirements (such as elastic ropes or certain seals that need to withstand a certain amount of tension), this performance parameter is critical. The high tensile strength ensures that the product will not be easily broken during 

 

use.
Melt flow rate: As a thermoplastic elastomer, melt flow rate is important for the machining process. The melt flow rate of YH-4010 will affect the difficulty of injection molding, extrusion and other molding processes. The right melt flow rate allows the material to flow better in the processing equipment, thus more efficiently manufacturing products with complex shapes and precise dimensions.
