Innegra™ Frequently Asked Questions
Q: What is Innegra™ S and Innegra™ H fiber?
A: Innegra™ S, an olefin fiber, is our primary product and the lightest commercial fiber available. (.84 g/cc)Innegra™ H (patent pending) is a series of hybridized yarns containing Innegra™ S co-mingled with a high modulus fiber such as Aramid, Basalt, Carbon, or Glass. Specifically engineered to meet industry demand for lightweight, damage and impact resistant composite solutions. It can be used in most reinfocement and composite manufacturing processes and has numerous applications in a wide range of industries.
Q: Where can I buy Innegra™ fiber?
A: Contact us at or +1.864.631.2800
Q: Where can I buy Innegra™ fabric or other reinforcements?
A: Please contact our office at +864-631-2800 or so we can refer you to the most appropriate converter.
Q: What reinforcements are currently on the market containing Innegra™?
A: Innegra™ is offered in braids, scrims, off angle, spread tow, uni-directional, multi-axial, pure woven Innegra™ fabrics, hybrid woven fabrics, co-mingled woven fabrics, and felts.
Q: Why should I use Innegra™ in my composite applications and what are the benefits?
A: Innegra™ is tough, durable, lightweight and can provide versatility, value, & safety.When combined with your current materials, Innegra™ can enhance the mechanical properties of your final composite part. Depending on your application and current materials, Innegra™ can reduce weight, vibration, and cost, while improving toughness and damage tolerance.
Q: What is the recommended processing temperature for Innegra?
A: 150°C or 302°F
Q: What are the benefits of using Innegra™ in ropes, netting and webbing?
A: Innegra™S fiber is the lightest commercial fiber on the market, helping to reduce weight in ropes and netting. It is also hydrophobic, resisting water absorption, has low stretch, and floats.
Q: What is the density of Innegra™S?
Q: Is Innegra™ UV resistant?
A: Innegra™ is now offered in UV resistant white fiber as well as black Innegra.
Q: Is Innegra™ offered in different colors?
A: Currently Innegra™ is offered in only black and white. As we continue to grow our applications and customer base we will look to expand our color offerings. Being an olefin fiber, it can be more difficult to produce deep, rich colors.
Q: Is Innegra™ available globally?
A: Yes. Please refer to our table above listing the companies that offer Innegra products.
Q: What can I do to promote better adhesion?
A: Olefin fibers, such as Innegra™ can present challenges in adhesion if you are not familiar working with olefins. Resin and fabric selection can certainly improve adhesion. Lower viscosity resins are preferred. Calculations must be done based on volume and not weight. Innegra™ fibers have a larger diameter even though they are lower density. At times Innegra may require 5-8% more resin content than carbon. You can contact us to discuss what resins we have tested and best recommendations. Tightly woven, thicker fabrics are not as permeable, therefore will be more difficult to wet out and gain adhesion. Select a fabric that will help with adhesion. It may take a bit of trial and error to find the correct ratios for your application.
If you are having trouble with adhesion or delamination give us a call, we are here to help +1 864-631-2800.
Q: What type of commercial products contain Innegra™?
A: Innegra™ has been used in F1 cars, police shields, kayaks, canoes, surfboards, stand up paddleboards, windsurf boards, kiteboards, paddles, helmets, Bauer hockey sticks, HEAD tennis racquets, ropes, and more.
Q: Can I use Innegra™ to replace carbon or glass?
A: No, Innegra should be used with carbon or glass to add impact resistance, durablity, or vibration dampening. It is not a one for one replacement. Careful attention must be paid to your laminate and required mechanical strength. Because Innegra will add ductility it is important to choose the right location for Innegra in your design. If you remove too much carbon or glass you will lose stiffness. We would be happy to discuss your design and help you come up with the correct ratio.
Q: What else do I need to know about working with Innegra™?
A: Other things to know about Innegra:
It is an Olefin fiber.
There will be a learning curve because it is a new material!
Different end use products = different recipes.
Low viscosity resins are preferred.
Volume to Weight ratios are important.
Increased resin content is necessary due to the volume of Innegra
Choose fabric for best permeability of resin
Can add ductility
