Rubber Material

SEBS is actually a form of thermoplastic elastomer (TPE) with styrene added. Green Peace lists SEBS as an acceptable alternative to PVC in toys. Polyolefin plastics such as Polyethylene (PE) and Polypropylene (PP) are the most common building blocks for SEBS, which don't need plasticizers (like phthalates) or stabilizers (like lead) for flexibility.

SEBS is used in a wide variety of general-purpose rubber items as well as in handlebar grips, toothbrushes, sports mouth guards, diapers (as the elastic component) and teethers. The chemical resistance of SEBS is similar to natural rubber, having excellent resistance to water, acids, and bases.

Product Description

SEBS

SEBS is a linear triblock copolymer of polyethylene as terminal segment and Ethylene butene copolymer obtained by hydrogenation of polybutadiene as elastic block in the middle. Its full name is Styrene Ethylene Butylene Styrene , or SEBS for short.

1.SEBS has good uv stability, antioxidant and thermal stability, so it can also be used in roofing and asphalt for road repair.
2.SEBS is soluble in paraffin wax and can be used as a flexible surface coating on paper products.
3.SEBS is temperature insensitive when heated without obvious shear flow, so it can be used as a template for IPN. (The basic principle of IPN is that two insoluble polymers can achieve the interpenetration of the entangled chain segments, so that the two insoluble polymers can be "locked" together by covalent crosslinking.)
4. Organic solution of SEBS oil blend can replace natural latex to manufacture surgical gloves and other products. Because SEBS does not contain unsaturated double bonds and has high purity, it has the following two advantages :

(1) good antioxidant and ozone resistance;

(2) Natural rubber contains protein that can cause dangerous allergic reactions in some patients, while this blend does not.

SEBS Physical and mechanical properties

Elastomers of styrenic block copolymers SEBS polymers are among the most versatile and easy to process in the plastics material. The EB XPRENE a very good coefficient of surface friction, low permanent deformation, a tensile strength. Normally they do not require drying, have broad processing latitude and have good to excellent thermal stability. Most commercial TPE can be processed by a variety of techniques. In addition, there are many degrees of specialty formulated to suit particular processes. Other features of the SEBS polymerThey include neutral base color, resistance to aging and UV radiation, the compression set and approval for food contact. The special qualities with specific acoustic properties, modified adhesion, heat stability and flame retardancy complete the current product range.

SEBS structure

Since the rubber blocks and hard polystyrene are incompatible, a strong phase separation results in the formation of polystyrene domains. These domains act as physical cross and can rupture and reset by a combination of shear and temperature links. The amount of shear required to process SBC depends on molecular weight of polystyrene (Mw) and the type of rubber midblock. Styrene-ethylene-butylene-styrene (SEBS) SBCs are usually not hydrogenated his predecessors strongest domains.

SEBS resin is a block copolymer of styrene base and butadiene elastomer, also known as Styrene-Ethylene / Butylene-Styrene (SEBS), thermoplastic elastomers, in which the elastomeric phase is modified by hydrogenation. The hydrogenation of an SBS rubber leads to the formation of an elastomeric segment in which the alternative ethylene units with the units of which butyleneiche name SEBS. Thanks to the absence of the double bond, XPRENE EB, have an excellent resistance to oxidation and can be added with plasticizers and fillers. SEBS polymer belongs to the family of thermoplastic elastomers in which the elastic phase is constituted by the rubber of SEBS (styrene-ethylene-butylene-styrene), and the plastic phase is generally of an elastomeric polyolefin phase. Due to its structure and behavior thermoplastic elastomers are located between plastics (SEBS thermoplastics) and rubber (elastomer). The thermoplastic SEBS combine the typical advantages of rubber and plastic materials. The products included in this class are compatible with polypropylene and are used for overmolding and extrusion. Its resistance to ultraviolet rays (due to its chemical nature SEBS rubber (is saturated), and devoid of double bonds, this makes XPRENE EB is particularly resistant to the action of UV rays and weathering), then makes them the ideal option for outdoor applications that require a high resistance to oxidizing agents.
