Heveatex Graft Polymers are a unique series of products for the rubber industry. They are produced by grafting methyl methacrylate onto natural rubber latex. As such, they will exhibit a combination of elastomeric and plastic properties.

These products will yield strong adhesion between such dissimilar materials as natural and synthetic rubber, leather, polyvinyl chloride, textiles, and metals. Conventional pressure-sensitive natural rubber compounds can be tie-bonded to various plastic bases, particularly polyvinyl chloride and polypropylene. If the vinyl pyridine used in tire cord adhesives is replaced with graft polymer latex, superior adhesion can be obtained.

Three graft polymer latices are currently available. They differ only in rubber to methyl methacrylate ratio. They are compatible with a wide variety of emulsion polymers and latices. When compounding graft polymer latices, allowances should be made for calculating curative ingredient levels. A solid version is also available which can be made into solvent-based adhesives/primers.
