I have some question about this material.1.Can we replace the styrene monomer in unsaturated polyester resin with any other chemical like vinyl tolooene or de allyl phthalate? 2.If we can replace it, it is a full replacement or no? 3.Is the other chemical price cheaper than the styrene monomer price? 4.Can we have a list of the producers of chemicals like styrene monomer or the replacement chemical which their location is near to our location:Iran?
