New foam gasket for sealing containers and manufacturing filters

This new product range of 200-litre drums is designed to carry materials in solid and paste form. When it comes to sealing the lid of the drum, Bayern-Fass has opted for a particularly tear-resistant and adhesive material with excellent compression recovery from Rampf Giessharze, specialists in the development, production and sale of resin systems made of polyurethane, epoxy and silicon.[image_0] Thanks to its very low viscosity, good adhesion, high mechanical strength and outstanding compression recovery, the Raku-Pur 33-1024 foam gasket from Rampf Giessharze is ideal for sealing containers and manufacturing filters. In addition, the semi-rigid moulded foam with integral skin is also very robust. The two-component system is water-repellent, has an abrasion-resistant surface and excellent chemical and ageing resistance. Due to its short pot life and curing time, the system is usually processed by two-component mixing and dispensing machines. In order to apply the foam gasket, Bayern-Fass has now integrated a new mixing and dispensing machine from sister company Rampf Dosiertechnik into its production system for new drums. The new dispensing machine applies the foam to the lids of the 200-litre drums before turning them 180 degrees and stacking them without altering the stripe dimension. The manufacturer recommends a curing time of two minutes for the moulded foam. The liquid system begins to react in 30 - 40 seconds, while the tack-free time is two to three minutes. Rampf Dosiertechnik is a leading manufacturers of low-pressure mixing and dispensing systems for processing one-, two-, and multi-component reaction resin systems. The companies in the Rampf group work together to provide the best possible material and machine solutions for their customers.
