Epic Resins offers a broad range of polyurethanes, engineered to meet the demands of diverse applications. A common question we hear is whether silicone-based systems are a better choice.
Silicones have some advantages, like resisting degradation at high-temperatures above 200°C. However, polyurethanes deliver on formulation versatility. Urethanes can be designed with superior thermal, physical, and chemical properties. Polyurethanes offer excellent protection at a lower cost—making them the preferred solution for many potting applications.
More Economical Polymer:
Polyurethanes often offer a lower cost for the raw materials and application processes they use.
Low Water Vapor Permeability (WVP):
Polyurethanes create a superior moisture barrier, significantly reducing water migration to protect sensitive components from corrosion and failure.
Minimized Outgassing:
Our polyurethanes are engineered with quality materials to exhibit exceptionally low outgassing, critical for protecting optical surfaces and sensitive sensors in enclosed environments.
Exceptional Operating Temperature Range:
Polyurethanes offer reliable operation across a wide thermal range of -60°C to 150°C with short excursions into higher temperatures, ensuring long-term durability.
Optimal Bond Strength:
Our polyurethanes are formulated for strong covalent bond strength to various substrates and casings, including metals, plastics, and ceramics, ensuring long-term durability.
Improved Physical Attributes:
Polyurethanes offer higher strength, elongation and abrasion resistance.
Enhanced Chemical Resistance:
Polyurethanes can be formulated to resist degradation from oils, solvents, and other harsh chemicals, extending product life.
Wider Formulation Latitude:
We can formulate our polyurethanes as soft as a silicone gel and as rigid as a highly cross-linked epoxy.
Our advanced laboratory capabilities enable us to deconstruct and analyze the molecular structures of competitive polyurethanes and silicones. This enables us to:
Reverse Engineer Formulations: Precisely replicate or improve upon competitor materials for a fraction of the cost and time.
Tune Critical Properties: Precisely adjust gel and cure time, viscosity, CTE (Coefficient of Thermal Expansion), modulus, and Tg (Glass Transition Temperature) to prevent issues like over-penetration or shrinkage.
From our high-quality raw materials to our ability to engineer polymers to specific properties, Epic Resins delivers polyurethanes that are verified and reliable.
