"From everything we have learned (which isn't nearly enough), KBLB will NOT be selling spider silk. Spider silk is made from the protein spidroin. It's a single strand without any substantial coating. Silkworm silk is made from a different protein, fibroin."

taken from kblb website which looks to have been recently updated:

"These recombinant spider silk fibers are composed of a unique combination of spider silk protein and silkworm silk protein."

Material Toughness [3] Tensile Strength [4] Weight [5]

Dragline spider silk 120,000-160,000 1,100-2,900 1.18-1.36
Kevlar® 30,000-50,000 2,600-4,100 1.44
Steel 2,000-6,000 300-2,000 7.84

The Company has conducted mechanical stress analysis testing on numerous select samples of BAM-1 recombinant spider silk, demonstrating strength at or exceeding 5 times the strength of hot-rolled steel. The Company is now scaling up production and commercialization of BAM-1 recombinant spider silk."
