THIOKOLLP Liquid Polysulfide Polymer

THIOKOL LP(Liquid Polysufide Polymers) is a liquid elastomer with low moisture permeability and outstanding chemical/oil resistance. It is a very special polymer having a sulfur structure used as a base polymer for sealant in construction and civil engineering projects, and plays a vital role in state-of-the-art construction technologies including construction of high-rise buildings. THIOKOL LP also has applications as a modifying agent for epoxy resins and polyurethane providing them with flexibility, durability, and weather resistance.

NPS-282 is a new polymer block-copolymer of LP and polyether that was developed specifically for sealants. By using isocyanate curing agents, it ensures long durability, despite wide movements of working joints, excellent paintability and a reater variety of colors, all of which other existing polysulfide polymers are unable to offer.

We are proceeding with the development of environment-friendly methods of manufacturing THIOKOL LP, and will gradually be switched over to these new methods.
