consist of a defined number of E-Glass filaments of a certain nominal diameter, brought together to form a yarn. The structure of the yarn is fixed and protected by a size and a slight twist, generally in Z-direction

Our E-Glass fiberglass yarns are wound on plastic bobbins and supplied in a “milk bottle” shape. Vetrotex glass yarns can be also supplied on beams. The glass composition meets the certification for E-Glass as defined by ASTM’s D578-00 Standard Specification for fiberglass filaments

is a starch/ silane /oil-based size system. Due to its special composition, all fiberglass yarns sized with T63 have a high tensile strength. The size abrasion is reduced to a minimum and the electric static build up is very low, even under demanding conditions.
Starch/ oil-based size system, being suitable for a large variety of textile processes.

5312 – Starch/ oil based size systems, especially designed for high speed air jet weaving machines and applications requiring good heat cleaning properties.
Starch-free plastic size systems, containing silane bonding agents guaranteeing an excellent compatibility with different resin systems (epoxy,phenolic and unsatured polyester).
These size systems are especially designed to provide excellent compatibility with PVC plastisols.
This size system is especially designed for texturizing, providing a very good protection for a mechanically demanding process and offering a high tensile strength.
