E7 entered batch production and customer supply
The E7 formulation entered batch production in 2014 and began supplying domestic and overseas customers. The report links it to large wind-turbine blades, high-pressure vessels and high-performance pultruded profiles, with claimed improvements in modulus, strength and softening temperature. The batch-production and supply stage is a reported commercial milestone. The cited passage does not supply grade-specific numerical performance values or establish that every application generated revenue.
