TPE 成为制造AZLA耳塞的优选材料

AZLA 是一家韩国音频设备企业，该公司使用凯柏胶宝® 的高品质热塑性弹性体 (TPE) 制作耳机的耳塞。作为全球 TPE 行业的领军企业，凯柏胶宝® 还将获得新产品的联合冠名权。这种材料具有出色的加工性能，可确保极佳的佩戴舒适度。

音频设备想要获得理想的音质和聆听体验，耳塞起到了非常重要的作用，它也是耳机的重要组成部分。SednaEarfit XELASTEC 耳塞是韩国耳机和音频设备制造商 AZLA 的最新产品。该公司选择了凯柏胶宝® 的高品质热塑性弹性体作为重要材料，确保在音质保真的前提下，实现耳塞的最佳贴合度。XELASTEC 是 AZLA 首款完全由热塑性弹性体制成的耳塞。

AZLA 首席执行官 Ashulley Lee 先生表示：“我们的研究显示，人们使用纯无线立体声（TWS）设备和耳机的平均时间越来越长。我们在 2019 年决定研发 XELASTEC 耳塞，可以长时间佩戴，且不会对耳朵造成压力。”

Ashulley Lee 先生补充说：“我们采购了许多种材料样品，经过深入研究后确定，凯柏胶宝® 化合物的高性能既符合国际安全标准，又契合我们的要求。在开发 XELASTEC 耳塞的过程中，我们与凯柏胶宝® 进行了紧密的合作。”

AZLA 通过分析人类耳道样本设计出了 XELASTEC 耳塞，利用这些信息找出最符合人体结构的设计，提高了隔音效果。

凯柏胶宝® 的 TPE 材料质地柔软，可塑性极强，可减少外壳振动以最大限度提高音频设备的声音表现，能完美贴合人耳，佩戴非常舒适。TPE 具备很多性能优势，包括高耐用性、高弹性、高回弹复原性、无毒、良好的抗疲劳性和出色的温度耐受性。

在 XELASTEC 耳塞的整个开发过程中共研究了大约 182,000 个耳塞，做出了 12 个试用模具。Ashulley Lee 先生强调：“我们对 XELASTEC 耳塞的开发投入了大量的时间和精力，确保满足严格的标准和要求。”

符合标准

SednaEarfit XELASTEC 使用的 TPE 材料符合美国 FDA 规定（原材料合规性）- 联邦法规（CFR）第 21 章和 EN71/3 标准以及欧盟法规第 10/2011 条，证明这种材料可以安全使用。

选择凯柏胶宝® 的材料不仅因为其独特的声学特性，还因为其材料柔软亲肤，由它制作的耳塞即使长时间佩戴，也不会伤害耳道的脆弱皮肤。

此外，由于凯柏胶宝® 的 TPE 材料具有高透明度、耐候性、耐化学性、低敏性和低压缩永久变形等特点，因此成为 SednaEarfit XELASTEC 的理想材料选择。

触感柔软，佩戴舒适

凯柏胶宝® 化合物触感非常柔软，可为佩戴者带来舒适的体验。TPE 材料的质地柔韧，弹性极佳，可以精确贴合耳朵轮廓，改善隔音效果。

SednaEarfit XELASTEC 在室温下可保持其原始形状，但将其放在耳道中后，体温会激活材料分子的活性反应，在耳道中轻微调整形状，完美契合耳道的轮廓。

此外，TPE 化合物可以紧紧包裹耳塞的出音口，最大限度减少共振，改善耳塞的贴合性。

SednaEarfit XELASTEC 耳塞易于安装在耳机上，使用非常方便。有了这些非凡的功能特点，XELASTEC 耳塞和耳机将为用户带来最舒适的聆听体验。

AZLA earpieces hit the right notes with KRAIBURG TPE

South Korea-based audio devices company AZLA has produced its earpieces from thermoplastic elastomer (TPE) compounds and co-branded it with KRAIBURG TPE. The material provides excellent processability and ensures high wearing comfort.

At the heart of the audio devices sound quality and listening experience is the earpiece, a vital component in earphones. When South Korean manufacturer of earphones and audio devices, AZLA, was seeking a material for its latest SednaEarfit XELASTEC earpiece, it selected a high-quality thermoplastic elastomer from KRAIBURG TPE to achieve the ultimate fit for the earpiece, while maintaining the sound quality. XELASTEC is AZLA’s first earpiece that is fully made of thermoplastic elastomers.

AZLA CEO Mr. Ashulley Lee said, “Based on our research we discovered that the average usage time for truly wireless stereos (TWS) and earphones is getting longer. In 2019, we decided to develop the XELASTEC earpiece that can be worn for a long period of time with no stress to the ear.”

Mr. Ashulley Lee added, “We sourced for many materials and after thorough research decided that KRAIBURG TPE’s compounds provided good material properties and comply with international safety standards. We worked closely with KRAIBURG TPE in developing the XELASTEC earpiece.”

AZLA designed the XELASTEC earpiece by analyzing samples of ear canals and utilized this information to develop a perfect earpiece fit for earphones, thus improving the sound insulation.

KRAIBURG TPE’s soft and pliable TPE material is used to maximize the performance of the audio device by reducing housing vibrations as well as providing a superb and comfortable fit for the ear. The TPEs are characterized by high durability, high elasticity and rebound resilience, non-toxic properties, good fatigue resistance and excellent temperature tolerance.

Throughout the development of the XELASTEC earpiece about 182,000 earpieces and 12 trial molds were studied. Mr. Ashulley Lee emphasizes, “We invested in a considerable amount of time and effort in the development of the XELASTEC earpiece to meet the exacting standards and requirements.”

In compliance with standards

SednaEarfit XELASTEC uses TPE that complies with US FDA regulations (raw material conformity)-Code of Federal Regulations (CFR), Title 21 and standard EN71/3 as well as EU Regulation No. 10/2011, allowing for safety of use.

Since the earpieces are in direct contact with the delicate ear canal for a prolonged period of time, KRAIBURG TPE’s materials were selected not only for their specific acoustic properties but also suitability for skin contact.

In addition, with its high transparency, resilience to weathering and chemicals as well as hypoallergenic properties and low compression set makes KRAIBURG TPE’s material is the perfect choice for the SednaEarfit XELASTEC.

Soft-touch feel for comfort

KRAIBURG TPE’s compounds feature a soft-touch feel that provides comfort to the wearer. The TPE material also provides flexibility and elasticity to allow for an exacting fit to the ear, with improved sound insulation.

SednaEarfit XELASTEC is able to retain its original shape at room temperature, but gently changes its shape when it is placed on the ear by exaggerating an active reaction of molecules with an individual’s body temperature, thus perfectly fitting the contour of the ear.

Also the TPE compound has improved the fit of the earpiece by holding the earphone nozzle tightly with minimized resonance.

The easy assembly of SednaEarfit XELASTEC earpiece with the earphone makes it convenient for the user. With all these features, the XELASTEC earpiece, together with earphone, provide for a comfortable listening experience.
