ALMARA, a Polish manufacturer of specialized butyl compounds, will exhibit at BAU 2027 in Munich, taking place from 11 to 15 January 2027. We invite construction material manufacturers, industrial partners and distributors to visit us in Hall B6, Stand 134. As one of the world's leading trade fairs for architecture,
Vacuum Bag Sealant Tape in Wind Turbine Blade Manufacturing Vacuum bag sealant tape is a relatively small component of the composite manufacturing system, but it plays an important role in producing wind turbine blades. Its primary function is to create a temporary vacuum-tight boundary between the vacuum bag film and
Is your butyl sealant not sticking to the substrate? The cause may not be the material itself. The problem can result from inadequate surface preparation, moisture, coatings, contamination, low application temperature, insufficient pressure, trapped air, or sealant creep under load. The most important step is to determine how adhesion failed
Mooney viscosity is a standardised torque-based index used to characterise uncured rubber. Despite its name, it is not a true viscosity measurement expressed in Pa·s. For butyl compounds, Mooney viscosity can be useful for raw-material identification, batch-to-batch consistency and process control—but it should never be used alone to predict mixing,
How Butyl Rubber Became One of the World's Most Versatile Sealing Materials Most people encounter butyl rubber every day without ever realizing it. Although its name is primarily known within the polymer and sealing industries, modern life would look very different without its unique properties. Thanks to this exceptional material,
Is Crosslinked Butyl Tape Better Than Conventional? Butyl tape is widely used in construction, the automotive industry, general manufacturing, and the production of composite components. In technical data sheets and marketing materials, the term "crosslinked butyl tape" appears with increasing frequency and is often equated with higher quality, greater adhesion,
DIRECT ANSWER There is no universal winner. Select butyl for conformable, permanently plastic lap or compression seals; EPDM for elastic gaskets or membranes that must recover after repeated movement and withstand outdoor ageing; and bitumen for waterproofing details designed within bituminous membrane or coating systems. When choosing between butyl and
A butyl sealant is one of the most widely used sealing materials in construction, industrial manufacturing, and the production of windows and doors. Thanks to its exceptional flexibility, excellent adhesion, and resistance to weathering, it provides long-lasting, reliable sealing for many years. Modern butyl mastic is used wherever airtightness, moisture
Most polymer materials we encounter every day—from sealants and tapes to flooring and automotive components—are much more than just the polymer itself. Their performance depends not only on the polymer matrix but also on a carefully selected combination of additives, among which fillers play a particularly important role. Fillers significantly
Butyl Compound Manufacturing – A Process Driven by Expertise, Technology, and Precision Butyl compounds are among the most demanding materials used in modern industry. Thanks to their exceptional sealing properties, chemical resistance, and extremely low gas permeability, they are widely utilized in the automotive, construction, energy, chemical, and technical manufacturing
