E-Glass Yarn

E-Glass yarn is a natural, lustrous, white, continuous filament yarn, which is evenly twisted on supply packages. The yarns are made of glass of high stability and durability and are, with the exception of sizing ingredients, inorganic, incombustable and will neither expand nor contract with moisture changes. The glass composition meets the certification for E glass as defined by ASTM’s D578-00 Standard Specification for Glass Fiber Strands.
Yarns
Yarns are defined as a continuous strand of filaments coated with an engineered chemical coating or size twisted together and used in weaving, knitting, braiding, plying and many other forms of fabric. AGY produces a full spectrum of yarns designed to meet your most demanding performance, processing and cost requirements by varying any one or all of the following fundamental components of the yarn:
glass chemistry
coating or binder chemistry
diameter and number of the individual filaments in the bundle
level and direction of the twist
Rovings
AGY does not make E Glass rovings.
Chop
Chop is a gathering of individual filaments that have been treated with an engineered coating or size and chopped to uniform length. The coating or size has been specifically engineered to allow the bundles of chopped fibers to flow while being delivered to the matrix that is to be reinforced, and then disperse within that matrix to ensure maximum reinforcement. AGY produces a full spectrum of chopped products designed to meet your most demanding performance, processing and cost requirements by varying any one or all of the following fundamental components of the chopped fibers:
glass chemistry
coating or binder chemistry
diameter, length and number of individual filaments in the bundle
