TIPS
RIM is the result of a reaction between two liquid components isocyanate and polyol
as they are injected into a closed mould at low pressure. The two components are
mixed together as they flow into the mould as a low viscosity liquid and the reaction, which increases the temperature and the pressure at the surface of the tool,
forms the polyurethane part in the tool cavity.
Polyurethane resins for RIM have grown into a broad range of formulations with
particular physical properties for specific performance requirements.
Rapid types can produce virtually anything from flexible elastomer substitutes,
to foam-core parts to extremely rigid, solid and thin-walled components.
Parts can be supplied primed, painted or surface treated with graphics to simulate
various textures such as carbon fibre.
