汽车安全气囊用密封胶

用于密封两片织物之间的接头/接缝时提供优异的粘合性能如剥离强度和内聚衰坏。将第一片和第二片粘结在一起,然后用一个或多个缝合线缝合在一起,以提供足够的机械强度。接缝通过有机硅粘合剂缝合,以在安全气囊展开时提供足够的不透气性或压力保持。

导热凝胶继承了硅胶材料亲和性好,耐候性、耐高低温性以及绝缘性好等优点,同时可塑性强,能够满足不平整界面的填充,可以满足各种应用下的传热需求。

导热凝胶相对于导热垫片,更柔软且具有更好的表面亲和性,可以压缩至非常低的厚度,使传热效率显著提升,最低可以压缩到0.1mm,此时的热阻可以在0.08℃·in2/W – 0.3 ℃·in2/W,可以到达部分硅脂的性能。另外,导热凝胶几乎没有硬度,使用后对设备不会产生内应力。、相对于导热垫片,更容易贴合接合面,相对于导热硅脂,具有更好的密封性,不易粉化。

Positioning itself in the new energy sector, Bonte’s innovative adhesive materials are driving the industry’s green transition

Against the backdrop of the ‘Dual Carbon’ policy, the new energy industry is entering a period of rapid development, with the pace of technological iteration continuing to accelerate for products such as power batteries, energy storage equipment and new energy support components. As new energy equipment is subjected to working environments characterised by alternating high and low temperatures, high vibration and heavy loads over extended periods, this places extremely high demands on adhesives in terms of bonding strength, resistance to high and low temperatures, insulation and protection, waterproof sealing, flame retardancy and environmental friendliness. High-performance, safe and eco-friendly adhesive materials have thus become a crucial safeguard for the safe development of the new energy industry.

With over twenty years’ experience in the adhesives sector, Bonte leverages its global R&D capabilities to drive high-end manufacturing.

At a time when high-end manufacturing sectors such as microelectronics, displays and new energy are undergoing rapid upgrading, adhesives are no longer merely auxiliary consumables, but rather key core materials that determine a product’s stability, precision and durability. The iterative upgrading of high-end manufacturing is driving adhesive materials to achieve continuous breakthroughs in terms of high precision, high compatibility, environmental friendliness and high stability. Materials companies possessing core R&D capabilities and proven industry experience are becoming vital pillars of the supply chain’s upgrading, with Bonte serving as a prime example.

Empowering Precision Manufacturing: Bonte Adhesives Help the Microelectronics Industry Improve Quality and Efficiency

With the rapid development of 5G, artificial intelligence and the smart device industry, microelectronic devices are continuously evolving towards miniaturisation, high precision, high integration and high reliability. The manufacture of core components such as chips, micro-components and precision circuit boards places the most exacting demands on adhesives in terms of bonding precision, insulation properties, high-temperature resistance and stability; even the slightest deviation in materials can directly affect the performance and service life of end products. Consequently, high-end specialised adhesives have become a critical and essential material for the upgrading of the microelectronics industry.
