On these pages we offer starting point formulations for pigment concentrates for the use in Decorative Coatings, General Industrial Coatings, Wood and Furniture Coatings and Household, Industrial and Institutional Cleaners, Polishes and Laundry Detergents. The randomness of these components along the chain make two polybutene molecules difficult to pack together nicely, thus lowering the melting point of the compound. More information about CAS and the CAS registry can be found here. Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: . Along the long central carbon atom chain in a polybutene molecule, these various starting butenes create repeating units with different kinds of branches (ethyl -(CH2CH3), methyl -(CH3) and dimethyl (CH3)2). Once cooled, it turns into a soft, elastic material due to its partially tetragonal crystal structure. This enables us to improve ads and website content.
