概述

氢化苯乙烯嵌段共聚物 (HSBC)  是一系列苯乙烯类热塑性弹性体。 用于大量热塑性弹性体化合物,可以加工成多种形式。特定等级经过认证后适用于消费品、医疗、移动和油品改性应用。这些苯乙烯热塑性弹性体涵盖广泛的应用,包括化合物、聚合物改性、粘合剂、柔性 PVC 替代品和减振产品。

氢化苯乙烯嵌段共聚物 (HSBC) 由苯乙烯基硬嵌段和氢化二烯软嵌段组成。由于硬嵌段充当低于聚苯乙烯玻璃化转变温度的交联点,而软嵌段提供弹性,因此HSBC 具备类似橡胶的弹性。氢化产生优异的耐热性和耐候性。

氢化苯乙烯嵌段共聚物 (HSBC)  分为多个等级,从低到高的苯乙烯含量,以及从低到超高的分子量均有。此外,在软块结构方面更提供四种不同的类型,分别是SEP、SEPS、SEEPS 和 SEBS。

我们提供各种等级,包括从低苯乙烯含量(软)到高苯乙烯含量(刚性),从低分子量(高流动性)到高分子量(更像橡胶的特性)。每个等级具备不同的功能特性,可用于各种应用。这些产品在不同的温度范围内表现出类似橡胶的特性。与非氢化苯乙烯嵌段共聚物相比,氢化苯乙烯嵌段共聚物 (HSBC)  具有更好的拉伸强度、更好的耐热性、耐候性和耐臭氧性以及与聚烯烃更好的相容性。


SEPS 结构(SEPS;苯乙烯-乙烯-丙烯-苯乙烯)通常不会结晶并表现出优异的拉伸伸长率和低温性能。 SEPS 2000 系列硬度范围广,可用于各种产品,如粘合剂、个人电子产品、医疗和消费品(如尿布)。

The Hydrogenated Styrenic Block Copolymers (HSBCs) is a series of styrenic thermoplastic elastomers. Is used in a great number of TPE compounds and can be processed in a wide variety of forms. Specific grades are certified and used in consumer goods, medical, mobility and oil modification applications. These styrenic TPEs cover a broad range of applications including compounds, polymer modification, adhesives, flexible PVC substitutes and vibration damping products. 

The Hydrogenated Styrenic Block Copolymers (HSBCs) consist of styrene-based hard blocks and a hydrogenated diene soft block. HSBCs exhibit rubber-like elasticity since the hard block acts as a crosslinking point below the glass transition temperature of polystyrene and the soft block provides elasticity. Hydrogenation generates excellent heat and weather resistance.

  • 3D printing

The Hydrogenated Styrenic Block Copolymers (HSBCs) is offered in a variety of grades, from low to high styrene content and from low to ultra-high molecular weight. Also, in terms of soft-block structure, there are four different types, SEP, SEPS, SEEPS and SEBS.

There is a variety of  HSBCs grades, from low styrene content (soft) to high styrene content (rigid), from low molecular weight (high flow) to high molecular weight (more rubber-like properties). Each provides different functional characteristics and can be used in various applications. These products exhibit rubber-like properties over a broad temperature range. In comparison to non-hydrogenated styrenic block copolymers,  HSBC exhibits better tensile strength, better heat, weather and ozone resistance as well as better compatibility with poly-olefins.


The SEPS structure (SEPS; styrene-ethylene-propylene-styrene) generally does not crystallize and exhibits excellent tensile elongation and low temperature properties. With its broad range of hardnesses, SEPS 2000-series is used with various products like adhesives, personal electronics, medical and consumer goods such as diapers.
