Resistant to Environmentally Acceptable Lubricants

New rubber compounds resistant to Environmentally Acceptable Lubricants (EAL) The shipping industry is on its way to become greener. The US Environmental Protection Agency (EPA) issued the 2013 Vessel General Permit (VGP) part of which regulates the use of lubricants on board vessels traveling through US waters.
