Estimed Yu-Xiang water supply materials Co.LTD,

I'm Alberto, Emiflex SpA purchasing department. 
We are looking for a business partner for EMIFLEX with the following questions:

The elastomers normally we used are the following :
NN (Neoprene on both the outside and inside);
EE (EPDM on both the outside and inside);
NP (Neoprene on the outside + Nitrile on the inside
NH (Neoprene on the outside + Hypalon on the inside);
NV (Neoprene on the outside + Viton on the inside);
Do you have all these types of elastomers available?

Can you provide us with documentation attesting to the certifications you have by UL/FM.DNV,ISO,WRAS,RINA, Llyoyd Registrer etc etc..
Can you send me the price list?

I look forward to hearing from you.
Best regards,

Alberto
