Overview
JS-EMC300-1040 is an E01 emulsion chopped strand mat made of E-glass chopped strands, randomly and evenly distributed and held together by an emulsion binder, part of the Jushi product line in our glass fiber range. JS-EMC300-1040 is compatible with unsaturated polyester and vinyl ester resins, and is supplied with supply chain resource support for formulators sourcing an emulsion-bound chopped strand mat for open-mold and closed-mold composite processes.

Applications of JS-EMC300-1040 in Hand Lay-up and Molding Processes
JS-EMC300-1040 is designed for use in hand lay-up, filament winding, compression molding, and continuous laminating processes. Its end-use applications include ships and boats, bath equipment, automotive parts, chemical corrosion resistant pipes, tanks, cooling towers, and building components.
Why the Emulsion Binder Matters for Hand Lay-up Production
Because JS-EMC300-1040 uses an emulsion binder to hold the randomly distributed E-glass strands together, the mat offers good wet-through and fast wet-out in resins, along with no flying objects during operation. Combined with high tensile strength, this makes the mat suitable for hand lay-up production of large-area parts where consistent resin impregnation and operator comfort both matter.
Why Sourcing Consistency Matters for Buyers
Because binder distribution and glass strand quality directly affect wet-out speed, resin impregnation, and finished-part mechanical properties, buyers should confirm current specifications for this chopped strand mat against the latest technical data sheet before scheduling a production run. A supplier that consistently delivers this mat with stable binder performance reduces the need to re-qualify a lay-up or molding recipe with every new batch.
This is particularly relevant for producers making ships and boats, tanks, pipes, cooling towers, and building components, where mechanical properties and wet-out consistency are directly tied to binder distribution and glass strand quality across the mat. Buyers should confirm current batch documentation against the latest technical data sheet before finalizing a production schedule.
What to Consider When Sourcing JS-EMC300-1040
Buyers evaluating JS-EMC300-1040 for the first time should confirm that its compatibility with unsaturated polyester and vinyl ester resins matches their formulation, and should review whether their process (hand lay-up, filament winding, compression molding, or continuous laminating) matches the mat’s intended application range. Requesting the current technical data sheet is a practical way to confirm that a given batch matches the product features described above.
Packaging, moisture-sensitive storage requirements, and transport classification should also be confirmed directly with the supplier, since chopped strand mat wet-out and binder performance can be affected by storage conditions. Buyers sourcing this mat for time-sensitive lay-up or molding schedules should discuss lead time and packaging requirements before finalizing an order.
General Handling and Storage Guidance
As with other emulsion-bound glass fiber mats, this product should be stored in accordance with the supplier’s technical data sheet, typically in a dry, temperature-controlled, well-ventilated area away from moisture and direct sunlight, since humidity and contamination can affect binder integrity and resin wet-out. Packaging should remain sealed until the mat is ready for use in the lay-up or molding process.
Buyers should request and review the current technical data sheet for JS-EMC300-1040 prior to receipt, and confirm that on-site storage conditions, including humidity control, are compatible with the product’s recommended storage requirements. Proper inventory rotation helps maintain the wet-out and mechanical performance described above.
