Our Fiberglass Mat Products
PrimeMat manufactures fiberglass mat for industrial composite fabrication. The range covers four reinforcement types: chopped strand mat (CSM), continuous filament mat (CFM), surface tissue, and combo mat.
All fiberglass products are made to order with custom specifications, ISO 9001 certified manufacturing, and low minimum order quantities.
Chopped Strand Mat (CSM)
E-glass/ECR-glass chopped strand mat for hand lay-up, filament winding, and compression molding.
Continuous Filament Mat (CFM)
Continuous filament mat with superior mechanical properties for RTM, pultrusion, and high-strength applications.
Surface Tissue
Fine fiber surface layer for smooth finish. Perfect for gel coat backing and surface aesthetics.
Combo Mat & Core Mat
Multi-layer combination mat (CSM + woven roving + core) for sandwich construction and thick laminates.
Carbon fiber fabrics
UD and biaxial carbon fiber fabric, sourced from certified partner mills and exported with the same PrimeMat QC and documentation handling.
Carbon Fiber Concrete Reinforcement
UD CFRP wrap fabric 200–600 g/m² with matched epoxy system for column wrapping, beam strengthening, and seismic retrofit.
Unidirectional Carbon Fiber Fabric
UD carbon cloth 200–600 g/m² with 3,400+ MPa fiber tensile strength, plus biaxial options for wind, marine, and structural use.
How to Choose the Right Fiberglass Mat
Match the mat to your molding process first, then to the resin system and the laminate weight your part needs. The four product types overlap in some processes, but each has a clear home territory.
Process compatibility
- Hand lay-up and spray-up: CSM is the standard reinforcement. Emulsion-bound CSM conforms to complex shapes; powder-bound CSM wets out faster.
- RTM and closed-mold injection: CFM or powder-bound CSM. Continuous fibers give higher strength and fewer voids in injected laminates.
- Pultrusion: CFM for profiles and structural shapes that carry axial loads.
- Filament winding and compression molding: CSM, used alone or combined with woven roving.
In short, choose CFM when the part needs higher strength, better dimensional stability, or a closed-mold process. Choose CSM when cost and conformability come first.
Resin compatibility
- Emulsion-bound mats suit polyester and vinyl ester resins.
- Powder-bound mats suit polyester, vinyl ester, and epoxy. For epoxy systems, specify powder binder.
- For hand lay-up with polyester or vinyl ester, either binder works. Emulsion feels softer and more conformable; powder is firmer and less sensitive to humidity.
Weight and layer selection
- Heavier mat builds thickness faster with fewer layers; lighter mat conforms better on tight radii.
- Surface tissue in the 30-100 g/m² range is a finish or barrier layer, not a structural one.
- Combo mat pairs CSM with woven roving in one roll (configurations such as 450/300, 600/450, and 900/600 g/m²), cutting lay-up time by roughly 30-40% compared to placing layers separately. Core mat adds a 2-10 mm core between skins for stiff, light sandwich panels.

How to Order: What to Specify
To get an accurate quote, include the following with your inquiry:
- Mat type: CSM, CFM, surface tissue, or combo mat
- Weight per area in g/m² (imperial weights also accepted)
- Width and roll dimensions; standard roll inner diameters are 76 mm or 152 mm
- Binder type and your resin system (polyester, vinyl ester, or epoxy)
- Glass type where it matters: E-glass, ECR-glass, or C-glass for acid service
- Quantity, packaging, and any third-party inspection requirements
MOQ starts from 2 tons per specification. A certificate of analysis (COA) ships with every shipment, and third-party inspection can be arranged on request. If you are unsure which mat fits your process, send your part drawing or laminate schedule and our engineers will map it to a mat specification.
