Product Description

NexGen® XL75 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® XL75 can be easily compounded with a variety of fillers and oils to attain the combination of properties and economics that you desire.

NexGen® XL75 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.

Storage and Hanlding

NexGen® XL75 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. 

Processing

NexGen® XL75 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.

Safety

These materials are intended for industrial use only and the practices of good housekeeping, safety and cleanliness should be followed before, during and after use.
