EDGETEK solves weight problem

16 November 2001

A custom EDGETEK high modulus compound developed by engineers at PolyOne Engineered Materials S.A. France was selected by Salomon to help significantly reduce the weight of a new model in their top-of-the-range inline skates, using a polyamide with 30 percent carbon fiber, generating a weight saving of 150g per pair while successfully maintaining the required stiffness..

The sports and leisure markets are increasingly demanding innovative materials providing better performance and weight savings, for example, while maintaining a highly aesthetically desirable finished product. Salomon develops and manufactures products that address the needs of customers with all levels of experience, while sustaining performance, safety and style.

One key challenge with the new model was to reduce the weight of the heel support frame by 10 percent, while maintaining the very high stiffness obtained with the 45 percent glass fiber-filled polyamide traditionally used.

Engineers at PolyOne Engineered Materials S.A. France developed the tailor-made EDGETEK compound using a polyamide with 30 percent carbon fiber, generating a weight saving of 150g per pair while successfully maintaining the required stiffness. However, initial testing revealed insufficient impact strength. After further research, drawing on PolyOne Corporation’s extensive knowledge of polymers, fillers and additives, a new sample was developed which provided more than double the impact performance thereby surpassing Salomon’s stringent requirements.
