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.

BONDING RUBBER AND PLASTIC SURFACES DURING INJECTION MOLDING
20220347899 · 2022-11-03 ·

An injection molded composite comprising a first bonding surface of a diene rubber composition bonded to a second bonding surface of a polar thermoplastic elastomer composition. There may be no more than 25% of the bonding surfaces having an adhesive applied to them or alternatively, no adhesive is applied. Furthermore, the polar thermoplastic elastomer composition was injected against the first bonding surface to form the second bonding surface and the first bonding surface has an active halogen moiety.

Fire hose and matertal therefore

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.

A LABEL FOR A TYRE OF VEHICLE WHEELS, A PROCESS FOR MANUFACTURING SAID LABEL AND A PROCESS FOR MANUFACTURING A TYRE INCLUDING SAID LABEL

Abstract: A label (1; 50) for a tyre (100) of vehicle wheels comprises: at least a first layer (4) which is made of an elastomer material which is compatible with the elastomer material of a sidewall (102) of the tyre, an external surface (2) which is intended to remain visible when the label is coupled to the sidewall, a plurality of recesses (10) which are formed at the external surface (2) and which are capable of generally defining at least one portion of information which is set out on the label (1; 50). The elastomer material of which the first layer (4) is made comprises a quantity of a halogenated isobutylene polymer greater than 5 phr.

20220340789 · 2022-10-27 ·

Conformable, stretchable, printable films are described. In particular, films that include a film substrate, a pressure sensitive adhesive, and a hybrid solvent barrier/primer layer including a blend of two copolyamides that are not miscible are described. Such hybrid solvent barrier and primer layers may be effective as both a solvent barrier and a primer layer.

Multilayer polymeric structure

The invention relates to multilayer polymer structures having at least three layers. These layers include a polar capstock layer other than an acrylic, an olefinic substrate layer, and a tie layer. The tie layer is selected from olefinic acrylate copolymers, a block copolymer of vinyl aromatic monomer with an aliphatic conjugated diene or a derivative thereof, a copolymer of olefin and (meth)acrylic acid partially or fully in the salt form, a high impact polystyrene, and/or a vinyl cyanide-containing compound. Each layer could contain multiple sub-layers. The multilayer structure exhibits excellent structural integrity, excellent surface appearance, high impact strength, high scratch resistance, and excellent resistance to UV rays.
