UL-Certified Flame Retardant Resin
Fire Retardant Epoxy and Polyurethane Compounds
Epic Resins produces a variety of epoxies and polyurethanes designed with fire-retardant properties. This protects any encased product or part while ensuring normal, stable operation. Here are a few of the flame retardant products we’ve formulated:
UL Recognized Epoxy and Polyurethane Potting Compounds:
Epic R1000-01/H5000 - UL 94 Certified Epoxy Potting Compound
Epic R1000-01/H5000 is a filled modified epoxy, stabilized for manual batch processing or through the use of dispensing equipment. This customizable epoxy allows for room temperature or elevated temperature curing options. Often used in resistors, diodes, capacitors and more.
Epic R1055/H5083 - UL 746 Recognized Epoxy
Epic R1055 is a premium fire retardant with UL recognition that is heavy metal free with a 180°C RTI, UL 746 rating of F1 for outdoor exposure and long work life. This epoxy is an excellent choice for your high-temperature potting applications, capable of penetrating tightly wound electrical coils.
Epic S7244 - UL 94 HB Epoxy Potting/Casting System
Epic S7244 mixes at a simple 1:1 ratio and is UL 94 HB recognized. This epoxy contains less abrasive filters, which makes it ideal for use in meter-mix and dispensing machinery. Epic S7244 is the perfect solution where thermal conductivity and electrical insulation is required.
Epic S7202 - RoHS Compliant Outdoor Polyurethane Potting
Epic S7202 has over 20 years of field-tested ability in outdoor applications in charge controllers, micro-inverters and control modules. This 2 part polyurethane potting compound series can be formulated in a variety of gel times to fit your application.
EPIC S7527 - Series UL 94 V-0 Recognized Polyurethane
Epic S7527 is a UL94 V-0 recognized 2 component polyurethane potting compounds that were formulated to provide a long gel time at a medium hardness with excellent electrical properties. EPIC S7527 is an excellent choice for potting and encapsulating sensitive electronics that are exposed to harsh environments.
Epic S7475 - Soft UL Compliant Potting Compound
Epic S7475 is a two-component polyurethane compound for potting electronic control modules (ECM’s) and a wide variety of electronic devices. The low mixed viscosity of the S7475 allows the material to flow into intricate areas under printed circuit boards and other tight tolerance areas. Another key property of this product is the 4:1 by volume mix ratio that allows the system to be very adaptable for meter mix and dispense processing. The very low hardness of S7475 in combination with the low Tg provides excellent flexibility, therefore allowing delicate surface mounted devices (SMD's) to expand and contract during thermal cycling and thermal shock. For applications that generate a great deal of heat, S7475 has shown extremely low weight loss at 130°C. S7475 is UL 94 V-0 recognized at 4.8 mm and is RoHS compliant.
Epic S7524 - Transparent UL Recognized Potting Compound
Epic S7524 is a transparent, UL 94 V-0 recognized polyurethane compound. S7524 features low mixed viscosity and transparent color. S7524 was designed for potting PCB assemblies for use in white goods. The transparent color also offers this product as an ideal candidate for applications requiring indicator LED's to display through the potting.
Epic RM2018 - Mid Shore A UL Recognized Potting Compound
Epic RM2018 is a two-component polyurethane potting and encapsulating compound that carries a UL94 V-0 flammability rating. RM2018 is designed for potting DC/DC Converters, GPS Sensors, and other electronic devices that require flexibility over a wide temperature range. RM2018 also features a convenient 4:1 volumetric ratio, low Tg and excellent electrical stability over various frequencies.
The Value in UL-Certification
Underwriters Laboratories (UL) is a leader in safety sciences and is globally recognized for producing safety solutions. Epic Resins sends many newly formulated epoxies and polyurethanes to UL for testing and certification. When a flame-retardant resin is recognized by UL, it means this resin has been tested and provides safety-related certification to manufacturers and consumers.
Epic Resins has decades of experience in specialty epoxy and polyurethane resins. Our professional staff uses superior customer service to work with clients to solidify their manufacturing production process. Our expertise provides clients the ability to maximize proactive product development and supply consistency to achieve maximum value.
Is there a difference between "flame retardant" and "flame resistant"?
Yes. Although the words “flame” and “fire” can be used interchangeably, there is a difference between the words “resistant” and “retardant.”
A “flame resistant” material is inherently resistant to igniting and will not melt or drip when exposed to extreme heat. While flame-resistant materials can catch fire, they’re not likely to ignite just from being near fire and many flame-resistant materials will actually choke a fire to the point of putting it out.
A “flame retardant” material is one that has been chemically treated to self-extinguish if it catches fire. Fire-retardant chemicals are commonly used on plastics and furniture to reduce the chance of a fire spreading.
Flame Retardant Resin Uses
