Abstract
The present invention resides in a boot seal for use in sealing a joint. The joint comprises first and second relatively movable parts. The boot seal is configured in the form of a sleeve to extend between and around the vehicle relatively movable parts. The sleeve has a laminate wall which comprises at least two layers of thermoplastic elastomeric material which are bonded together. At least one of the layers is a stretch-toughenable polyester thermoplastic elastomer which has been diametrically stretched in an amount effective to increase the toughness of said one layer. The laminate wall has a percent elongation to rupture of at least 100, and a flexural modulus which is less than 100,000 psi. The laminate wall preferably has a puncture resistance of at least 50 Newtons/mm wall thickness.
