FAQ:
Q:What is the difference between FR4 and 3240?
A:Raw materials resin and glass cloth are different.The mechanical strength and electrical properties of FR4 are higher than 3240, and FR4 has V0 flame retardancy.The price of 3240 will be cheaper and the density will be a little bit higher, the performance will be a little bit worse.
Q:What does fr4 mean?
A:FR4 material is a rigid insulation material made of imported alkali free glass fiber cloth impregnated with imported epoxy resin and added with flame retardant and adhesive.
Q:How do you cut fiberglass tubes?
A:The forming process of glass fiber tube is that the glass fiber impregnated with resin is cured in a high speed polymerization device of photoelectrothermal integration, and then formed by traction and pultruding.Because the thin wire of glass fiber tube is not easy to cut off and often has the phenomenon of connecting the wire, so can use special grinding wheel cutting machine, electric saw cutting machine, laser cutting machine to cut, the cutting cost of grinding wheel and electric saw is cheaper than laser.
Q:What are fiberglass tubes?
A:Fiberglass tube is a kind of pultrusion formed FRP composite material, which is a thermosetting elastic material formed by continuous fiberglass coarse sand and resin under the traction of pultrusion molding machine.The rich resin layer on the surface makes it have good anticorrosion.Common fiberglass tubes include FR4 G10 G11 3240 tubing.
