PVDF, also known as poly(vinylidene difluoride), is a man-made polymer of 1,1-difluoroethylene. It's most commonly used as an insulative coat for electrical cables, but because of it's diversity as a material is also widely used in the Aerospace, Chemical, Construction, Military, Fishing, Medical and Semiconducting industries in various forms including those such as coatings, piping, tubing, sheets, films, plates, foams and insulators.
PVDF has a high electrical resistivity, with a volumetric resistivity of 200,280 ohms per cubic metre, and a surface resistance of approximately 500,700 ohms per square metre, making it an ideal insulator and useful for coating fishing lines and wires.
PVdF can also be made into a membrane form used to immobilize proteins, and is a highly flexible and tensile material, with a good chemical and solvent resistance.
As far as specific dates go, I couldn't tell you much else about PVDF from my knowledge of the material, and, unless by PFA you mean Paraformaldehyde, I couldn't tell you anything about that either, sorry. I hope the information I have been able to provide helped, though!

Is it your responsibility to contact your child's father if he has a history of violent behavior and he knows how to contact you?
As custodial parent, it is your responsibility to ensure the relationship between the non-custodial parent and the child is maintained even if he can contact you. You want to maintain the "better parent" status, so that if you go to court, you have a record of the attempts you made vs. the attempts he made. Even if a PFA is in place "for you", it is still not reason for you to deny your responsibilities of attempting to maintain the other-parent/child relationship. If there is a PFA in place for both of you, then it will be presumed that any contact would be at a minimum anyways. If there is no PFA, don't just use "his past violent nature" as an excuse. If there's really "past violent nature", then get a PFA to protect yourself and/or your child. Also, an appropriate custody order should be requested from the court. Keep in mind, these can be changed. So if his nature gets better, then visitation can be improved. If his violent nature worsens in the future, then you can do another request for the PFA and a more restrictive visitation schedule.
