NexGen® XL81 partially cross-linked butyl rubber with a moderate degree of cross linking that is designed to be easily incorporated into a variety of butyl rubber tapes and sealants to impart better creep resistance and resistance to flow at high temperatures.
NexGen® XL81 can be easily compounded with a variety of fillers and oils to attain the combination of properties and economics that you desire.
NexGen® XL81 comes in a pelletized form to make it easier to handle and measure into batches. The pellets also make it easier to disperse in a variety of solvents.
NexGen® XL81 may agglomerate over time. The agglomeration accelerates with ambient heat. Store in a cool, dry environment to prevent damage to the bags and to minimize agglomeration.
NexGen® XL81 can be compounded in most rubber processing equipment, including Banbury and Sigma blade mixers or on a two-roll mill. Pumpable sealants and adhesives can be produced by adding the pellets to an appropriate solvent in a high-speed homogenizer or disperser.
