摘要：

Rubber is mixed with glass flakes to form a mixture, which is sheared to form a preform with aligned glass flakes. The final shape of the article may be formed by cutting the article from the preform or may be formed by extrusion or moulding. The shearing may be achieved by a calendering operation. Alternatively, shearing may be achieved by milling, injection moulding or extrusion through a die. The rubber may include a vulcanizing or cross-linking agent and may be subjected to a vulcanization or curing step once it has been formed into its final shape. Rubber articles such as seals, tyres, hoses and lining sheets with glass flakes, exhibit improved fluid impermeability.
