Aalten/The Netherlands — In the Finnish town of Äänekoski a new manufacturing plant for bioproduct is under construction. The bioproduct mill is part of a pulp mill with an annual production capacity of 1.3 million tonnes. In addition to pulp, the new mill will produce a number of other bioproducts. This will generate more bioenergy than is used, so that no fossil fuels will be needed for powering the mill.

The manufacturer’s sealant is part of a system, which creates fire-resistant, gas-proof and smoke-proof seals in cable and pipe transits. The grey version of this sealant will be used in the Finnish bioproduct mill to seal 1,500 m of joints. Its properties include resistance to sodium hydroxide (lye). This is used at various stages of the manufacturing process and can come into contact with the sealant used in the concrete joints. The sealant is also resistant to a large number of other external influences. Moreover, the system is fire resistant, gas-proof, smoke-proof and waterproof.
