Besaflex according to company standards
Besalfex® waterproofing profiles made of plasticized PVC are distinguished by many good characteristics and economic efficiency. Plasticized PVC has been used since the 20th century and is the subject of constant research. This material has not been used for waterproofing profiles until it has proven appropriate, as a result of scientific checks performed to prove positive features and, in particular, its resistance over time.
By fulfilling all the required demands, the Besaflex sealing profiles resist the largest structural forces required. They resist acidic and alkaline solutions, decompositions, as well as all natural agents.
Nitriflex® according DIN 18541
The Nitriflex® waterproofing profiles according to DIN 18541 are made of the highest quality materials and thus have very few restrictions, which far exceed the DIN standards. Nitriflex waterproofing profiles according to DIN18541 specifications are characterized by high resistance to stretch, chemical resistance and permanent elasticity to the rubber.
Elastoflex® according DIN 7865
Elastoflex® – The waterproofing profiles are made of elastomers. Elastomers are high-yield polymers bonded to bonded, vulcanised synthetic bonding parts (synthetic rubber). Due to these connections to the non-reversible coupling parts, special joints are required. Elastoflex®-Sealing Feels are ideal both in structures and in major joints, frequent load changes and low temperatures.
Polyflex according to company standards
Polyflex-sealing profiles are aimed at developing structural sealing loads. The sealing profiles have no connection deformations and can be used for sealing joints in concrete or plastic sealing covers.
Poliflex sealing profiles made of modified PE offer the advantage of good welding, aggressive chemical resistance, high durability and microbial resistance. The permanent elasticity and dilation characteristics are not affected by the decreased temperatures.
TPE according to company standards
Waterproofing profiles made of thermoplastic elastomers, designed for tear resistance, low temperature flexibility, weather-resistant and UV radiation.
