SP 1068 is a thermoplastic alkylphenol resin supplied in flake form and primarily used in rubber compounding applications. It is indicated for promoting tack over extended processing periods in various synthetic and natural elastomers. The product is commonly incorporated in tire compounds, tire treads, hoses, belts, and other rubber articles where controlled tack properties are required during processing.
SP 1068 is typically added at the beginning of the mixing cycle, together with elastomers, in open mill or internal mixer (Banbury-type) systems. The resin supports process consistency in rubber formulations where extended green tack is required.
The product is supplied in standard 25 kg bags and bulk packaging options as per manufacturer specifications. Official technical documentation is available upon request.
