Technical Parameters
Storage
Unless otherwise specified, fiberglass products should be stored in a dry, cool and rain-proof area. It is recommended that the room temperature and humidity should be always maintained at 15C ~35C and 35% ~65% respectively. To ensure safety and avoid damage to the product, the pallets should not be stacked more than three layers high. When the pallets are stacked in 2 or 3 layers, care should be taken to correctly and smoothly move the top pallet.
Packaging
* The product can be packed on pallet or in small cardboard boxes.
Long Fiber Injection Process (PU-LFI)
Long fiber injection process (PU-LFI) is a relatively new process technology for reinforced PU composites, combining ideas from the Spray-Up and SRIM processes. In this process, the roving is chopped into 1.0-10 mm length near the mixing head of a high pressure (RIM-like) machine. The mixed polyurethane and chopped strands are sprayed in a closed mold, which is under controlled temperature and pressure or spacing. The resulting reinforced polyurethane parts can be of very low density, depending on the allowed PU foaming.
