Styrene and 1,3-Butadiene.
Temperature range of white Buna-N is -25 to +180 C. But for Black Buna-N -20 to +170 C
Any link with Texas. Bu - from butadiene Na - from natrium N - from nitrile

1. Buna-N: nitrile rubber, also known as , Perbunan, or NBR, is asynthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Trade names include Nipol, Krynac and Europrene.Nitrile butadiene rubber (NBR) is a family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers (1,2-butadiene and 1,3-butadiene). Although its physical and chemical properties vary depending on the polymer's composition of nitrile, this form of synthetic rubber is generally resistant to oil, fuel, and other chemicals (the more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material).2. Buna S: a styrene-butadiene rubber
A seal material compatability chart available at ... http://www.danamark.com/files/Chemical_Compatibility.pdf Would recommend Buna-n for Salt water service.
Buna S rubber is a type of synthetic rubber made up of two monomers put together to form a polymer. It was invented by German scientists in 1935.
