(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

Information
目前，市面上常見的聚氨醋、環氧樹脂、丙烯酸醋等類型的膠粘劑，不耐強酸、強堿，固化后膠層易產生氣泡缺陷，使用不方便，抗剝離、抗開裂及抗沖擊性能較差，無法完全滿足目前汽車行業的要求，因此需研發新型的汽車用膠材料。聚硅氧烷主鏈Sl-0的鍵能為425 kJ/mol,遠大于C-C的345 kJ/mol和C-。的351 kJ/mol，穩定性好、耐候性優異。同時，聚硅氧烷分子體積大，內聚能密度低，具有優異耐沾污性、耐高低溫性、疏水性、透氣性等，能在一60一200 ℃長期使用;其力學性能如拉伸強度、撕裂強度、伸長率、硬度等因環境溫度變化而改變很小，安全可靠，使用壽命長。有機硅制品除具有耐輻照、耐高低溫性能外，還具有低吸濕性、高絕緣電阻、低介電常數、低應力、減振、環保、低毒性、難燃等優良特性，因此，有機硅聚氨酯密封膠廠家的發展前景廣闊，同時也將汽車用聚氨酯密封膠廠家的發展推向了新的高度。
有機硅聚氨酯密封膠廠家作為汽車用功能材料時，對汽車的減震、隔音、耐候、耐油等性能起決定性作用，雖然只占車用材料用量的很少一部分，但附加值高、利潤空間較大。隨著有機硅聚氨酯密封膠廠家新用途、新品種的不斷開發，預計未來其消費量仍會以較快速度發展，而動力正是來源于其在建筑和汽車領域的應用。2015年我國有機硅聚氨酯密封膠廠家產能為850 kt/a，產量約為760 kt，國內企業產量超過一半。發展中國家市場的快速成長將帶動全球需求的提升，預計2020年全球有機硅聚氨酯密封膠廠家需求量將達到1 790 kt。目前，有機硅聚氨酯密封膠廠家在汽車領域越來越受到歡迎，因此需加快加深其研究，其中的車燈膠和其它部位用膠是主要的2個研究方向。www.hryfc.com
