Product Introduction
M1-A, M1-H and M1-N E-glass Chopped Strand Mats are composed of chopped glass fiber strands that are bonded together into mats with a highly soluble polyester powder. Chopped strand mats are used primarily for hand lay-up, filament winding and press molding of FRP parts. Their many excellent characteristics have been used to provide superior performance in a broad range of end-use markets such as marine, transportation, recreation, construction, consumer and anti-corrosion.

Product Description
M1-A, M1-H and M1-N Chopped Strand Mats are designed to be compatible in an unsaturated polyester system. To help ensure the quality of customers' products, the quality management programs of manufacturing these products is controlled under the requirements of ISO 9001. M1-A and M1-H chopped strand mats have obtained the quality certification of the Norway Boat code.

Packaging
The Chopped Strand Mat is wound into a roll on a cardboard inner tube. All densities are 30cm (12") in diameter. Each roll is wrapped with a plastic bag and placed in a cardboard box. 12 or 18 boxes are placed vertically on a pallet, which is stretch wrapped.

Storage
Unless otherwise specified, it is recommended to store glass fiber products in a cool, dry area. Temperature should not exceed 35°C (95°F) and the relative humidity should be kept below 75%. Fiberglass products must remain in packaging material until just prior to its use. If these conditions are respected, the glass fiber product should not undergo significant changes when stored for extended periods of time.

Stacking
To ensure safety and avoid damage to the product, skids should not be stacked more than two high. When stacking two pallets high, care should be taken to correctly and smoothly place the top pallet.
