TPE和TPR差异

1。外观手感

TPE亚表面吸收，亮度低，触感光滑。TPR反射光强，亮度高，触感橡胶弹性好，平滑度低于TPE

2。基材

在弹性体工业TPE中，基于SEBS改性的热塑性弹性体通常被称为弹性体，而基于SBS改性的热塑性弹性体被称为TPR，TPR弹性优于TPE。其中TPE具有饱和分子结构，耐老化、耐黄变、耐温、耐腐蚀性能优于TPR。性能

3。温度通常TPR可以在150°C左右进行热塑性加工，而TPE需要在180°C左右进行热塑性加工，当然，这取决于它们的分子量，如果分子量较高，加工温度也较高

4。燃烧和气味

热塑性弹性体燃烧产生带有芳香气味的轻烟。TPR燃烧产生的烟雾是较浓的黑色（因为SEBS是氢化SBS，氢含量高，无烟雾燃烧，味道小。）

5。化学性质

SEBS作为SBS氢化产物，其化学稳定性、耐老化、抗紫外线、耐水解和耐温度等性能均优于SBS，因此，以SEBS为基质合成的热塑性弹性体优于以SBS为基质合成的热塑性弹性体。需要指出的是，有些地方可能称之为定制原因，苯乙烯弹性体改性材料TPE，TPR称为TPR，但忽略了材料存在SEBS和SBS基材的差异

6。SEBS的性能和应用

SEBS是利用氢化使脂肪族双键饱和以扩大应用范围。饱和热塑性弹性体SEBS由于软段为饱和烯结构，其耐候性、耐热老化性优于SBS，且物理性能也更强、更坚韧，因此被广泛应用于生产高档汽车、医疗设备材料、玩具、电线电缆等领域。SEBS材料无毒，对人体组织不产生过敏、变异和排斥反应，具有良好的气密性、耐温性、耐老化性，可采用高温蒸煮和紫外线直接消毒，可作为医疗器械的基本材料，如手术套管、手术服、输液管、止血带、血液分离器、，橡胶塞等等

TPE and TPR differences

1. appearance feel

TPE sub-surface absorption, low brightness, smooth touch. TPR bright reflection, high brightness, tactile rubber elasticity, less smoothness than TPE.

2. substrate

The thermoplastic elastomer modified on the basis of SEBS is generally referred to as the elastic body in the elastomer industry TPE, and the thermoplastic elastomer modified on the basis of SBS is called the TPR,TPR elasticity better than the TPE. one TPE has saturated molecular structure, aging resistance, yellowing resistance, temperature resistance, corrosion resistance is better than TPR. performance

3. temperature

Usually TPR can be thermoplastic processing around 150°C, and TPE need to be thermoplastic processing around 180°C, of course, depending on their molecular weight, if the molecular weight is high, the processing temperature is also higher.

4. combustion and smell

TPE combustion produces light smoke with aromatic flavor. The smoke produced by TPR combustion is thicker black (because SEBS is hydrogenated SBS, high hydrogen content, no smoke burning, and small taste. )

5. chemical properties

SEBS as SBS hydrogenated products, its chemical stability, aging resistance, UV resistance, hydrolysis and temperature resistance and other properties are superior SBS, Therefore, the TPE synthesized from SEBS as substrate is better than that synthesized from SBS as substrate. We need to point out that some places may call the custom reason, the styrene elastomer modified material TPE,TPR is called the TPR,, but neglects the material existence SEBS and the SBS substrate difference.

6.SEBS Performance and Applications

SEBS is to use hydrogenation to saturate aliphatic double bonds in order to expand the scope of application. Saturated thermo-plastic elastomer SEBS because the soft segment is saturated ene structure, the weathering resistance, heat resistance aging is better than SBS, and the physical properties are also stronger and tougher, so it is widely used in the production of high-grade cars, medical equipment materials, toys, wire and cable and other fields. SEBS material is non-toxic, does not produce allergy, variation and rejection to human tissue, has good air tightness, temperature resistance, aging resistance, can use high temperature cooking and ultraviolet direct disinfection, so it can be used as the basic material of medical instruments, such as surgical sleeve, surgical clothing, infusion tube, tourniquet, blood separator, rubber plug and so on.
