GB-SR caulks | SW caulking Common name: GB flexible filler, GB plastic filler, SR flexible packing, SR flexible packing, plastic waterproofing material, elastic sealant GB flexible filler for its wide range of uses, it is usually too is known as caulking sealant, GB-CL flexible filler, GB-SR caulks, flexible putty sealant, sealing putty, SW caulks, etc., is designed for concrete panel, rockfill dam peripheral joints and expansion joints Sealing and development and production of new sealing material throughout the material, with special rubber as raw material which has a unique, high plasticity, heat resistance, cold resistance, aging resistance, but also a simple, non-toxic, odorless, water-resistant, sticky attached performance is good. GB flexible filler is designed for concrete face rockfill dam seam sealing characteristics of the development of a new type of caulking sealing material flow is the key material CFRD sealing surface can also be used as other concrete structures embedded joint surface sewing materials, alternative materials commonly used foreign joint seal CFRD IGAS-MASTIC series. GB biggest feature is a flexible filler has excellent deformability and fluidity in the water under pressure can flow, squeeze seam sealing role played excellent impermeability, capable of pores, cracks play a role in sealing closure . GB flexible filler also has good bonding properties, and concrete bonding strength greater than the tensile strength of the material itself, ensures that damage does not occur in a variety of conditions bonding interface. Meanwhile, GB flexible filler also has excellent chemical resistance, namely water, alkali salt soak, the environment has a strong applicability, resistance to freeze-thaw cycles, and have some cold resistance and temperature resistance. GB flexible filler may need to be processed into a variety of shapes and sections according to the size of the profile, to facilitate construction. In recent years, our company produces GB flexible filler, has on more than a dozen water, electricity and industrial engineering, civil engineering applications, have achieved good impermeable sealing effect.
