浅谈热熔压敏胶的耐高温特性!
 
目前,市场上大多数的热熔压敏胶都是针对室温下的某些具体胶黏性能而开发或设计的通用型产品。在真实的应用世界中,并不是每一种热熔压敏胶都需要具有耐高温的特性。今天就跟随小编一起来学习一下,希望可以帮到大家!
耐高温性热熔压敏胶对于汽车用内饰或能够粘贴在汽车内部操作的产物来讲是需要的。
 
这是由于在某些地区的炎地利代,汽车内部的空气和某些金属配件的温度可能会超出90℃。在这类高温景象中,大大都SBC基的热熔压敏胶城市初步软化。
 
由于操作的景象温度已经濒临或超出配方中苯乙烯物理性交联相的软化点,介于90-110℃。是以,在必定的剪切力浸染下热熔压敏胶会初步勾当或移动。
 
 杭州大伟胶粘剂有限公司专业生产各类热熔胶棒(粒)、热熔压敏胶。所用原料均采用于国内外著名企业,并辅以先进的生产配方、生产技术、生产出品质优良的EVA热熔胶棒(粒)及商标纸,标签,双面胶,医用,鞋材,汽车配饰,封箱,封盒等类的热熔压敏胶,产品无毒、无味、,并通过欧盟ROHS及美国ASTM--D4236认证,是理想的无毒环保型粘接材料,可广泛用于医用,印刷,汽车,卫材,建筑、玩具工艺制品、电子产品、金属制品、木制品、塑料、布料、陶瓷、纸盒包装、书刊粘合、机械等优先域。
On the high temperature resistance of hot melt pressure sensitive adhesive!
At present, most of the hot-melt pressure-sensitive adhesives on the market are general-purpose products developed or designed for some specific adhesive properties at room temperature. In the real application world, not every kind of hot-melt pressure-sensitive adhesive needs to have the characteristics of high temperature resistance. Today, I will study with Xiaobian. I hope I can help you!
High temperature resistant hot-melt pressure-sensitive adhesive is necessary for automobile interior or products that can be pasted in the interior of automobile.
This is due to the fact that the temperature of the air inside the car and some metal parts may exceed 90 ℃ in some areas. In this kind of high temperature scene, most of SBC based hot-melt pressure-sensitive adhesives are initially softened.
The operating temperature is close to or beyond the softening point of the physical crosslinking phase of styrene in the formula, which is between 90-110 ℃. Therefore, the hot-melt pressure-sensitive adhesive will initially act or move under a certain shear force.
Hangzhou Dawei adhesive Co., Ltd. specializes in producing all kinds of hot-melt adhesive bars (granules), hot-melt pressure-sensitive adhesive. All the raw materials used are used by famous enterprises at home and abroad, supplemented by advanced production formula and production technology, to produce EVA hot-melt adhesive sticks (granules) with excellent quality, as well as brand paper, labels, double-sided adhesive, medical, shoe materials, automobile accessories, sealing boxes, sealing boxes and other types of hot-melt pressure-sensitive adhesive. The products are non-toxic, tasteless and pollution-free, and have passed the European ROHS and American ASTM-D4236 certification, which is ideal The non-toxic and environmental friendly adhesive materials can be widely used in priority areas such as medical, printing, automobile, sanitary materials, construction, toy technology products, electronic products, metal products, wood products, plastics, cloth, ceramics, paper box packaging, book and magazine bonding, machinery, etc.
