(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
耐過熱水和蒸汽性能
過氧化物硫化的氟橡膠優(yōu)于胺類和酚類化合物硫化體系，在新型高溫高壓硅烷改性聚氨酯密封膠配方設(shè)計過程中考慮了耐過熱水和蒸汽性能。
耐壓縮性及天候老化性能
改性氟橡膠具有耐壓縮永久變形性能，在高溫下的壓縮永久變形性能十分關(guān)鍵，并具有極好的天候老化性能，經(jīng)過長時間自然老化后仍保持很好的性能。
高硬度和強度
以改性氟橡膠為材質(zhì)的新型高溫高壓硅烷改性聚氨酯密封膠要求膠料有較高硬度和強度，采用了高性能的進(jìn)口補強劑和輔助補強劑組成的雙補強體系，使該膠料具有合理的成本和良好的加工工藝性。
自潤滑性能
二硫化鑰加人膠料后，使膠料具有良好的自潤滑性能，對抗摩擦的能力大大提升，非常適用于油田熱采井的工況環(huán)境。采用高壓注壓硫化工藝生產(chǎn)，成型后分段硫化，保證了內(nèi)在品質(zhì)和精美外觀。
性能指標(biāo)
為了確保研制開發(fā)的油田用新型高溫高壓硅烷改性聚氨酯密封膠膠料能夠滿足復(fù)雜井況的應(yīng)用，特委托國家橡膠密封制品質(zhì)量監(jiān)督檢驗中心西北橡膠塑料研究設(shè)計院橡膠密封制品檢驗實驗室進(jìn)行檢驗，檢驗結(jié)果表明，采用耐高溫的改性氟橡膠材料，300℃下連續(xù)媛燒永久變形率36%，拉伸強度11.8 MPa，拉斷伸長下降率31%，膠料各項指標(biāo)均符合行標(biāo)HG/T2701-199油氣田用壓縮(YS)式封隔器硅烷改性聚氨酯密封膠標(biāo)準(zhǔn)要求。http://m.hbxqtax.com/
