STRUCTURAL REACTION INJECTION MOLDING MATS

Continuous strand glass reinforcing mats used in the SRIM process are pre-cut into a shape resembling the profile of the finished part. The mat is placed into the open half of the mold. Resin is either poured into the mold or the mold half is clamped into position dry. Two or more resins are then mixed together and injected under pressure into the cavity. Glass mats used in SRIM must be strong enough to resist resin wash out under high injection pressures and open enough to not trap air or gasses in the finished parts.

Superior SRIM Mats:

•N-751
This mat consists of dense fibers and is used to reinforce either flat or semi-contoured parts.

•N-754
This mat is more open than N-751 and is used to reinforce either flat or semi-contoured parts.

•N-764
This material is constructed to improve resin wet-thru characteristics.

All Superior SRIM mats are available with “A Type” binder formulation. This binder is a variation of our highly soluble regular binder with improved polyurethane compatibility.

And very importantly, we only use BoronFree ACR Glass in manufacturing our FRP mats. This is the top grade glass that resists corrosion and produces customer-winning quality parts.
