(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.

       新版国家标准《硅酮和改性硅酮建筑MS密封胶》将于2018年8月1日实施。与旧版(2003版)相比,主要变化在于,在标准适用范围方面,新标准相比2003版在适用于单组分有机硅MS密封胶的同时,增加了多组分有机硅MS密封胶,以及单组分和多组分改性有机硅MS密封胶。新标准对“改性有机硅建筑MS密封胶”进行了定义:以端硅烷基聚醚为主要成分、室温硫化的单组分和多组分MS密封胶。技示指标方面,级别由2003版的25 , 20变更为50, 35, 25, 20;下垂度项目的垂直和水平两种要求,变更为仅垂直方向的要求;质量损失率由,10%调整为,8%;挤出性由,80 mI/min调整为)150 mI/min;增加了烷烃增塑剂要求(彻底消灭“白油”这一劣质增塑剂的危害);对多组分MS密封胶增加了适用期要求。公司解释,报告期内,国内宏观经济增速放缓,公司所处有机硅行业竞争加剧,经营面临较大挑战。原材料上游方面,在供给侧结构性改革以及环保督查的压力下,有机硅上游单体价格大幅上涨,占公司有机硅室温胶原料成本60%以上的07硅橡胶和201硅油,采购价格上涨幅度超过50%,导致公司产品成本大幅增加。下游应用领域方面,公司传统应用领域房地产行业受国家宏观调控等因素影响,行业增速放缓。www.sdyuantai.com
