Polyurethane Resin and Epoxy Systems for Structural Casting
For Filter Casting, Edge Casting, Wet Cast, Grinding Media, and Polishing Media
Rely on structural casting resins engineered for your production process, from manual operations to fully automated manufacturing. Our reactive one-component and two-component systems based on polyurethane resin (RAKU® PUR) and epoxy (RAKU® POX) are developed for wet cast, filter casting, edge casting, and grinding and polishing media.
What Is Polyurethane Resin?
Polyurethane resin is formed when a polyol (component A) reacts with an isocyanate (component B). Depending on the raw materials and additives selected, the result can be a foam, a soft and elastic material, or a hard solid. For casting materials, raw materials are added to achieve a harder texture than in foams. Under the RAKU® PUR brand, RAMPF offers a wide range of two-component polyurethane systems, including casting and bonding systems. Learn more about the chemistry in our glossary entry on polyurethane.

FAQ
Our structural casting resins are used for filter casting, edge casting of doors, school desks, laboratory furniture, and desks in trains, wet cast forms, and grinding and polishing media. Beyond structural casting, polyurethane as a material is used in many industries, including automotive, electronics, furniture, packaging, household appliances, and energy technology.
Both are reactive resins that are usually mixed from two components and cure into a solid. Polyurethane resin can be formulated from soft and elastic to hard, adheres very well to plastics, and its reactivity can be set flexibly, including systems that cure at room temperature. Epoxy resin is a thermoset that is very strong and chemically stable. Our application consulting helps you select the right material for your requirements.
Yes. We formulate hardness, viscosity, and pot life to match your application, whether you process the resin manually or on automated mixing and dispensing systems.
Yes. Alongside systems that we tailor to your requirements, our portfolio includes filter casting systems with FDA-compliant formulations.
Yes, as long as it is applied properly and suitable personal protective equipment such as safety goggles and gloves is used. In all measurements of the MDI content at RAMPF, the result was below the maximum allowable concentration (MAC), in some cases up to 100 times lower.
No. RAMPF supplies its structural casting resins exclusively to industrial users and business customers and supports them from concept development to series production. RAMPF does not currently sell to private individuals or the consumer market.
