METHOD FOR THE PRODUCTION OF AN ELASTIC LAMINATE AND LAMINATED ELASTIC PRODUCT

A method for the production of an elastic laminate, with the following steps in a production line: coextrudeing a first web of elastic film with at least three layers, with at least two different polymer materials, to feed contemporaneously said coextruded first elastic film web and two second nonwoven webs to a thermal, binding calender, wherein the first elastic film web is arranged between said two second nonwoven webs when entering the calender; wherein said first elastic film web, during the movement from the coextrusion step to the thermal binding step, passes from a melted state, to a solidified and cold state when entering the calender, to join, through spot welding in said calender, said second nonwoven webs with respective opposite outer layers of said first elastic film web, thus producing an intermediate web, to stretch mechanically said intermediate web according to a direction transverse to the same web.

The second layer is thermoplastic and has a loss modulus at 1 hertz and 25° C. of less than or equal to 60 megapascals and comprises a thermoplastic elastomer and a polyamide. The third layer contacts the second layer opposite the first layer and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is sandwiched between the first and third layers. A method of making the multilayer film by coextrusion is also disclosed.

METHODS FOR APPLYING POLYURETHANE COATINGS TO GOLF BALLS HAVING A THERMOPLASTIC POLYURETHANE COVER
20230088331 · 2023-03-23 · ·

Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)—light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.
