3842, similar to NEMA G11, made of glass fabric impregnated with epoxy resin, then heated into prepreg and rolling into the rod shape, finally put into the different diameters molds, under high temperature and pressure to cure into the rigid laminated rods. 3842 is similar to G10/FR4, with the addition of a higher operating temperature and some improved mechanical strength at elevated temperatures.
Delivery
Standard specifications: 1-2 weeks (when stock is sufficient).
Custom sizes: 3-4 weeks (requires new molds or special processes).
FAQ
FAQ
Q: What's the difference between NEMA Grades G11 and FR5?
A: Flame Resistance: FR5 has enhanced flame-retardant properties compared to G11.
Usage Context: Choose G11 for general applications requiring strength and insulation; select FR5 for environments where fire safety is critical.
Q: What is G11 rod made of?
A: G11 rod is made from woven glass fabric impregnated with epoxy resin.
Q: What are the temperature limits for G11 rods?
A: G11 rods can be used continuously at temperatures up to 130°C (266°F).
Industry trends
Market demand: The demand in the new energy vehicle and wind power sectors has grown significantly, and it is estimated that the market size will reach 60 billion yuan by 2025
