  • Product description

High solid content foaming high solid latex PYLX-6618 refers to the styrene butadiene latex with a solid content of more than 60%, which is mainly used in the emulsion fields of latex sponge mattress, carpet sponge backing and asphalt. The preparation of high solid content styrene butadiene latex is divided into one - step method and two - step method. Although the preparation methods are different, the key is to synthesize large size and wide size distribution of latex particles.

The one-step method is a low water ratio, high conversion, without concentration can synthesize high solid content emulsion.

Generally, semicontinuous method is used. The actual conversion rate is about 95% and the solid content is 60% ~ 63%. The advantage of this method is that latex with high solid content can be synthesized directly in one step without the need of post-concentration treatment. The difficulty is later in the reaction. To overcome the high conversion rate of high viscosity, high stirring requirements, long reaction time, low efficiency, late reaction is easy to produce more gel and other problems.
