Building Materials

The butyl rubber as the main part, adding a certain proportion polyisobutene, black and white carbon black, compound additive, vulcanizing agent, plasticizer, softener and other fillers makes GB flexible filler. Its main material is butyl rubber, and the finished production is similar to putty, so it is also named butyl rubber sealing putty or putty sealant.
GB flexible filler, which is designed specially for concrete panel, rockfill dam peripheral joint and expansion joint, is the new type of waterproof material. It is widely used in water conservation, electric power engineering, industry and civil construction works. And it has achieved good impermeable sealing effect in these projects.
GB flexible filler can be divided into two kinds according to appearance: stereotypes filler and non-stereotypes filler.
Features:
Good deformability and fluidity. It can flow under the pressure of water, and it has waterproof effect after squeezed into the joints. It has good impervious performance, so it works in the sealing and waterproof of small openings and cracks.
Good gluing property. The bonding strength of GB flexible filler and concrete is greater than the tensile strength of the material itself. And it can ensure that damage of bonding interface will not occur under various working conditions.
Excellent performance of resistance to medium. That is to say, it is resistant to water and alkali salt soak. It has strong suitability to environment, and it is resistant to the cycle of freezing and thawing. What& acute;s more, it has a certain cold and high temperature resistance.
GB flexible filler can be processed into various shapes and section sizes according to needs to facilitate construction.
Package:
The stereotypes filler can be processed into various sizes as customers& acute; requirements, and the non-stereotypes filler is 25kg/bag (carton).
