Short Fibers with High-Strength Results

Mix this milled glass with any resin, body filler, or casting material to increase strength, bulk, and dimensional stability for parts.

  • Milled glass helps reduce shrinkage and increase moduli for parts, so it's popular for electrical/automotive components.
  • It is often used with vinyl ester resin as a corrosion-resistant, blister repair putty for deep boat hull damage (a ketchup consistency delivers best results).
  • Both fiber length and bulk density are controlled by the screen size—116" refers to the hole diameter of the hammermill screens used to mill the fibers, and lengths may vary up to this dimension.

For similar properties, but smaller fibers, see the 132" Milled Glass Fiber, #38.

This filler is compatible with epoxy, polyester, and vinyl ester resin systems. Add filler after adding catalyst to resin.

Add fibers to resin 5% by weight.


Fillers, when ordered alone, will typically ship in a small or medium box. Where possible, we will combine ordered items to reduce the number of boxes shipped.


1/16 Inch Milled Glass Fibers These Milled Glass Fibers are available in a variety of sizes: One 1/2 gallon (#29-A) One carton (#29-B) One box (#29-C) One box (#29-D)

I used this for making a bedding paste to fuse separate components together. It's easy to blend and very - very strong.

Good product.

Great high strength filler

Milled fiberglass is a great filler for use with epoxies and fills a gap left by other fillers when it comes to strength. Consistent size, easy to work with and excellent wettability.
