ALWA PERM

ALWA MOULD P is a cold curing casting resin for the production of porous moulds, slabs and blocks for the ceramic industry. It is a porous and high-strength plastic, which is well-suited for high pressure casting applications. ALWA MOULD P can be used in various areas of the tableware and sanitary ceramics, technical ceramics, plastic mould procedure as well as various filtration processes. The high stability and defined porosity of the material allows highly accurate mould surface reproductions. With ALWA MOULD P various geometric moulds for filtration processes of suspensions can be produced. ALWA MOULD P can be used for ceramic slip pressure casting procedures. In this procedure, water is removed by a filtration process of a clay suspension (slip), so that an increasing clay layer is built on the mould wall over time. The moulds, slabs and blocks of ALWA MOULD P are easily machinable (e.g., drilling, milling).

ALWA POR is porous and has a smooth surface structure. The product is characterized by a high stability, pressure-resistance and a long-term heat resistance of over 190°C. It is especially suitable for moulds with fine and complex structures. The good air permeability leads to a uniform stretching of the foil in the process of thermoforming. With this innovative product the annoying drilling of vacuum holes becomes obsolete and thus no visible markings are left on the thermoformed foil. Larger dimensions can be achieved by screw connections. Longer and wider dimensions by gluing. ALWA POR is easily machinable: Sawing, drilling, grinding, polishing. It also remains porous after polishing. ALWA POR is especially suitable for vacuum thermoforming and vacuum forming and is additionally suitable for - aeration of aquaria, fishponds and sewage treatment plants, - venting of injection moulds and blow moulds, - any proceedings of hot steam or water steam processing, - vacuum clamping

ALWA EPT 210 is a laminate and backfilling resin. Laminates can be produced with ALWA EPT 210 in order to manufacture glass fibre plastic parts, gauges, templates, moulds and applications with diverse fillers. ALWA EPT 210 is an epoxy resin that has a low viscosity and a light yellow colour. Under exothermic reaction, it cures in connection with the light yellow hardener H 10 at room temperature. The mixture shows a low viscosity and is particularly appropriate for laminating layers of up to 8 mm. For thicker laminates the application of layers must be interrupted several times in order to avoid too high reaction temperatures in the laminate.

ALWA EPF 10 is a temperature-resistant, steel-filled gelcoat based on epoxy resin. It is used to produce temperature and abrasion resistant surfaces for vacuum, PU foam, thermionic moulds and heating plates, among others.
