This 3 part system includes 6 base stocks which when vulcanized produce tough, durable elastomers with nominal Shore A durometers of 30, 40, 50, 60, 70 and 80. Additionally, the base stocks may be blended to produce elastomers of intermediate durometer. The 6 base stocks were developed to be compounded with ‑40 and ‑55.
