p-toluenesulfonamide USES

1. P-toluene sulfonamide is an excellent solid plasticizer for thermosetting plastics. It is suitable for phenolic resin, melamine resin, urea-formaldehyde resin and polyamide resin. A small amount of coordination can improve the processability, make the curing uniform, and give the product a good gloss.

2. P-toluene sulfonamide has no softening effect of liquid plasticizer, is incompatible with polyvinyl chloride and vinyl chloride copolymers, and partially compatible with cellulose acetate, cellulose acetate butyrate and cellulose nitrate.
