Ralph Noble was a co-founder in 1961 of Carlew Chemicals Ltd. which later became Synergies Industries, a Canadian-based company listed on the Montreal and Toronto stock exchanges. As the first Sales Manager (later Vice-President and then President), engineer by training, he brought previous vinyl ( B.F. Goodrich 1950-54) and polyolefin (CIL 1954-61) experience to this tiny company specializing in vinyl compounding and plasticizer production.

As President and CEO of Synergies Industries, he oversaw company growth from annual sales of ~$30 million (Can.) to ~$300 million divided almost equally between Canada (4 plants) and the US (2 plants). Synergistics became the dominant factor in the vinyl W&C industry.

Nobel supported research on renewable starting materials for synthesis of critical plasticizers and many other joint research programs with the Universities of McGill, Montreal, Toronto, and Waterloo, and with the National Research Council of Canada. In the business area, he supported: the construction of a marginal plant in Calgary, Alberta, although insisting on the take-or-pay contract from the major customer; the purchase of companies in Canada and the U.S.; the IPO of the company in the mid 1980’s; and the computerization of the company in the mid ‘90s.

Many of Noble's accomplishments have been summarized in an article in Plastics in Canada, April/May 1996, entitled “Ralph Noble created a Canadian revolution.” It refers, quite rightly, to Ralph’s often quote that “human capital is our most valuable capital.”

Noble served as President of the Society of Plastics Engineers (SPE) in 1970.
