S7140 - 2 Component Polyurethane Casting Compound
Epic S7140 is a two component polyurethane casting compound. S7140 features a fast gel time and rapid hardness development for pattern duplication and solid casting. S7140 has a 5:2 by volume mix ratio and contains no filler thereby minimizing air entrapment while mixing.
S7149 - 2 Component Urethane Casting System
Epic S7149 is a two component, quick curing urethane casting system. This product features an easy to use 1:1 mix ratio by volume, a low mixed viscosity for duplicating intricate parts, fast demold times and a low peak exotherm of 121C in any size mass. Epic S7149 is especially suited for use in fiber reinforced composites.
S7307 - 2 Component Urethane Casting Compound
Epic S7307 is a two component urethane casting material designed to produce a rigid material in a rapid cure. With a Shore D Hardness of 60-70, Epic S7307 is not as brittle as some other rigid polyurethane polymers.
What is RIM?
Reaction Injection Molding (RIM) involves the process of mixing two parts of a polymer together in an impinging mixer where it is put under high pressure, injected into a mold and then left to cure. The polymer mixture can be adjusted by the experts at Epic Resins to make the perfect polymer for your product and specific needs. By adding certain reinforcing agents, the resulting polymer can be strengthened or weakened per your preference.
The low viscosity of RIM means large complex parts can be easily made at a fraction of the cost of other molding processes. Because the chemical expansion creates the molding pressure, the RIM process requires less clamping force than other procedures, allowing use of smaller machines, which decreases costs. The process also allows for slim but durable and strong polymer plastic products with tight tolerances and complex geometries, making it ideal for larger single-piece moldings.
What is made using RIM?
RIM is used to create everything from automotive bumpers to dashboards, MRI covers and even components in windmill blades. With RIM, you have a substantial amount of freedom when it comes to designing your product. The process doesn’t limit you as much as traditional molding might. Certain forms of polyurethane are used for their unique applications such as acoustic and thermal insulators. Epic Resins knows the diverse functions of the RIM process in detail, our strong polyurethanes make your components durable and flexible without compromising structure or size.
